The disease appears after a tick bite. Symptoms and consequences of a tick bite in humans. Tick-borne encephalitis vaccines made in Germany

(Lyme disease), ehrlichiosis, anaplasmosis and a number of other diseases transmitted by ticks.

Every year up to 400 thousand Russians apply to medical institutions about tick bites, a quarter of the victims are children under 14 years old. It is not known how many tick bites citizens of our country receive during foreign trips.

Maximum amount suctions are registered in the Siberian, Volga and Ural federal districts, the minimum - in the South and North Caucasus.

The attack of ticks is characterized by seasonality. The first cases of bites are in early spring with an average daily soil temperature above 0.3 0 С, the last ones are in deep autumn. The maximum number of tick bites falls on the period from mid-spring to the first half of summer.

Not all ticks are carriers of infections. Free from pathogens on average in the regions of Russia are up to 80-90% of ticks.

However, the attack of sterile ticks (not carriers of infections) is also dangerous for humans! Mass suction is accompanied by sensitization ( allergic reactions) organism.

Ticks are potential carriers of one, and sometimes several types of microbes and viruses at once. Accordingly, the carriage of one pathogen is a mono-carrier, and two or more pathogens is a mixed carrier. In regions with high density tick populations are carriers of:

mono-infections - in 10-20% of cases;

mixed infections - in 7-15% of cases.

The tick is attached to the human body with the help of a hypostome. This unpaired outgrowth performs the functions of a sensory organ, attachment and bloodsucking. The most likely place for a tick to stick to a person from the bottom up:

groin area;

abdomen and lower back;

chest, armpits, neck;

ear area.

During a bite, under the action of tick saliva and microtrauma, inflammation and a local allergic reaction develop on the skin. The suction site is painless, manifested by reddening of a rounded shape.

The site of a tick bite in Lyme disease (borreliosis) looks characteristic - in the form of a specific patchy erythema, which increases to 10-20 cm in diameter (sometimes up to 60 cm). The shape of the spot is round, oval, sometimes irregular. After some time, an elevated outer border of intense red color forms along the contour. The center of erythema becomes cyanotic or white. The next day, the spot looks like a donut, a crust and a scar are formed. After two weeks, the scar disappears without a trace.

Signs and symptoms of a tick bite in humans

A tick bite is not accompanied by pain in humans. A sucked tick is able to go unnoticed for a long time.

Signs of a tick bite appear after two to three hours:

weakness, drowsiness;

• aches in the joints;

  photophobia.

The intensity of bite signs depends on:

the number of sucked mites;

individual features the human body to which the tick has stuck.

Strong manifestation of bite signs should be expected in the elderly, children, those with a history of chronic diseases, allergies and immunodeficiencies.

The first symptoms of a tick bite:

hyperthermia up to 37-38 0 C. against the background of a decrease in and;

tachycardia (more than 60 beats per minute);

difficult, hoarse breathing;

nervous reactions in the form of hallucinations, etc.

Temperature after a tick bite

An increase in temperature in the first hours after a bite is a sign of the development of allergic reactions to the saliva of a sterile or infected tick.

After a tick bite, body temperature must be recorded daily for ten days! Fever, diagnosed 2-10 days after the bite, is one of the signs of the onset of infectious pathogenesis.

Features of fever in major infections transmitted by ticks:

cardiovascular system - blood pressure jumps;

Bad outcome:

Persistent organic syndrome with a significant decrease in the quality of life in the form of a defect in motor functions without progression of symptoms;

A persistent decrease in the quality of life with the progression of symptoms (continuous progression, abortive - recurrent).

Contribute to the progression of symptoms: alcohol, overwork, pregnancy. Long-term persistent changes in the form of epilepsy, hyperkinesis - a reason for determining III, II, I disability groups.

Disability is determined by a special medical commission:

Disability III group: moderate paresis of the limbs, rare epileptic seizures, loss of labor skills, a significant decrease in professional qualifications;

Disability II group: pronounced paresis, hemiparesis in combination with epileptic seizures, a pronounced change in the psyche, severe asthenia, loss of labor activity and the ability to self-service;

Disability group I: severe motor disorders, frequent Kozhevnikov epilepsy (a type of epilepsy), widespread hyperkinesis in combination with epilepsy, dementia (acquired dementia), persistent loss of the ability to self-service and self-control of behavior, inability to move without assistance.

Diseases transmitted by ticks include viral, microbial (including rickettsial) and protozoan infections. Such diseases are diagnosed on almost all continents of the globe.

Human viral infections transmitted by ticks:

Tick-borne encephalitis (territory of Russia, Austria, Czech Republic, Finland, Germany, Hungary, Sweden, Switzerland, Poland, Slovakia, Baltic countries, Kazakhstan, China, Japan, Korea, others);

Tick-borne hemorrhagic fevers (Crimean-Congo hemorrhagic fever (South of Russia, China, Serbia, Bulgaria, Central Asian countries, Congo, Kenya), Omsk hemorrhagic fever (Omsk, Novosibirsk, Tyumen, Kurgan, Orenburg regions);

Rare tick-borne fevers (Lipovnik fever (European countries), Kemerovo fever (Kemerovo region).

Human microbial infections transmitted by ticks:

Borreliosis (everywhere in Russia, Eastern Europe);

Erlichioz (Russia, Eastern and Western Europe, USA, Japan, China);

Anaplasmosis (Russia, Europe, North America, China).

Microbial (rickettsial) human infections transmitted by ticks:

Marseille fever (southern Europe, South Africa, Asia, in areas with a humid hot climate, Crimea, Dagestan, the Caucasian coast of the Black Sea);

Astrakhan spotted fever (Astrakhan, Volgograd regions, Republic of Kalmykia, western Kazakhstan);

Tick-borne typhus of North Asia (Siberia, Khabarovsk, Primorsky Krai, Northern and Eastern Kazakhstan, Armenia, Turkmenistan, Mongolian People's Republic);

Tick-borne typhus of northern Australia (Queensland);

Smallpox rickettsiosis (found in Central Africa, Southern Europe, USA);

Tsutsugamushi fever (Primorsky Krai, Kuriles, Kamchatka, Sakhalin, India, Sri Lanka, Malaysia, Indonesia, Pakistan, Japan, Korea, China);

Q fever (Regions of the Volga region, Western Siberia, Central Black Earth, India, USA, France, Canada, Tunisia, Mali, Morocco, Western Ukraine, Spain, other countries);

Tick-borne paroxysmal rickettsiosis (previously in Western Ukraine, there is currently no data on the distribution).

Human protozoan infection transmitted by ticks:

Human babesiosis (Scandinavia, France, Germany, Yugoslavia, Poland, Russia, US East Coast).

The first step is to remove the stuck tick. A live tick must be stored/transported at ambient temperature, a dead (crushed) tick must be kept in a thermal container with ice.

Tests for tick infestation are carried out in the laboratories of Rospotrebnadzor (they are accredited and certified for these tests). In some regions, research is carried out by other laboratories, their addresses and phone numbers can be found on the Internet.

Antibiotics for a tick bite

Antibiotics are not always used to suppress pathogens transmitted by ticks.

In the treatment of tick-borne encephalitis (pathogen virus), antibiotics are not used.

Principles of treatment of a patient with tick-borne encephalitis:

Bed rest in a hospital for the entire period of fever and seven days after its end;

In the first three days - human immunoglobulin against tick-borne encephalitis;

Shown are prednisolone, ribonuclease, blood substitutes - reopoliglyukin, polyglucin, gemodez;

With meningitis - increased doses of B vitamins, ascorbic acid;

With respiratory failure - intensive ventilation of the lungs (IVL);

In the recovery period - anabolic steroids, nootropic drugs, tranquilizers.

Depending on the form of tick-borne encephalitis, an antibiotic may be prescribed as an auxiliary drug to suppress the microflora that caused complications in the lungs, intestines, kidneys and other organs. The type of antibiotic is selected by the doctor, based on the sensitivity of microorganisms to it.

In the treatment of borreliosis (Lyme disease), antibiotics are required! They are used to suppress pathogens. Lyme borreliosis is caused by a microorganism from the group of spirochetes.

Principles of treatment of patients with borreliosis:

Hospitalization is mandatory for neurological disorders;

At the stage of erythema (redness), tetracycline and drugs of its group are prescribed. Bacteriostatics (this group includes lincomycin, chloramphenicol, macrolides) prevent the development of later stages of the disease;

Neurological syndrome is helped to stop intravenous injections of bactericidal antibiotics of the cephalosporin and penicillin series. The group of bactericidal antibiotics also includes aminoglycosides and polymyxins;

Restoration of water balance - blood substitutes, physiological solutions, prednisolone, vitamins, drugs that normalize cerebral circulation, anabolic hormones.

As a means of etiotropic therapy in the treatment of tick-borne infections:

viral nature (see the list above), antibiotics are not used to suppress the virus, instead they use the method of specific immunotherapy;

bacterial nature (list see above) antibiotics are used;

protozoan nature (see the list above) use drugs that inhibit the growth and reproduction of protozoan microorganisms.

First aid for a tick bite

The victim must be helped to remove the tick, place it in a sealed container and sign the label accompanying the biomaterial sample.

The suction of a tick provokes an allergic response of the body, sometimes in the form.

Signs of Quincke's edema develop within a few minutes or hours in the form of:

Eyelids, lips and other parts of the face;

muscle pain;

difficult breathing.

This is a very dangerous manifestation of an allergic reaction, you must immediately call ambulance and try to help the victim before the arrival of doctors.

At home, you can do the following:

give one of (claritin, suprastin, erius, telfast, zyrtec and others);

provide access to fresh air;

introduce prednisolone (dexamethasone) at a dose of 60 mg intramuscularly.

Diagnostic and therapeutic measures for possible infections are carried out in medical institutions.

Where to go for a tick bite?

It is necessary to perform the following algorithm of actions:

remove the stuck tick;

take it to an accredited laboratory for the detection of infectious agents by PCR (see below for the address);

donate blood (if necessary) to detect antibodies to ELISA in human serum (details below).

undergo a course of treatment according to the results of laboratory tests and clinical indications.

1. Remove the stuck tick

The suction of the tick occurs after fixing it on the human body. This process takes from several minutes to several hours. Absorption of blood lasts from two hours to several days. Suction is imperceptible to humans, and a tick already drunk with blood is round and gray in color.

A sucked tick must be removed urgently, but very carefully! It is necessary to protect his abdomen from damage and leakage of hemolymph and human blood. Hands and the wound at the site of the bite should be treated with an alcohol-containing solution (vodka, cologne, alcohol solution of iodine or brilliant green).

Removing a tick with improvised means:

Throw a thread in the form of a loop around the proboscis (close to the skin), tighten and slowly pull it out with swinging movements. Instead of threads, you can use nails, two matches and other suitable items.

Place the tick inside a plastic bag, tie the neck.

Sign the label for the package (indicate the date, time, place of detection, full name of the person from whom the tick was removed, contacts for obtaining information about tick infestation).

Removing a tick with a special tool:

Use medical (manicure) tweezers or devices (Tick Twister, Tick Nipper, Pro tick remedy, Trix, Tricked off, others);

Place the tick in an airtight container (medicine bottle, for example);

Sign the label on the container (see above).

You cannot remove the tick on your own - contact the nearest emergency room, emergency department of a medical institution, surgical clinic, polyclinic. The list of institutions that work around the clock and provide emergency assistance in case of a tick bite can be found on the website of the territorial department of Rospotrebnadzor for the corresponding region.

2. Take the tick to an accredited laboratory

Analyzes are carried out free of charge, but it is imperative to clarify this information. PCR study based on ready-made diagnostic kits AmpliSens TBEV (encephalitis, borreliosis, anaplasmosis, ehrlichiosis), distributor InterLabService LLC. We need to know when the results will be ready. Usually the same day or next morning.

3. Donate blood to detect antibodies

Within 10 days after the bite of a tick, on the recommendation of a doctor, it is sometimes necessary to donate blood to detect antibodies in humans to infections transmitted by ticks. For diagnostics, the test system "VektoVKE-IgG-strip" of CJSC "Vector-Best" is used. Analysis time: 2 hours 30 minutes.

When donating blood, be sure to indicate the date of vaccination against tick-borne encephalitis (if any). The presence of vaccine antibodies gives false positive results. The information provided will reduce the time to determine the diagnosis and increase its accuracy.

According to the results of research on the tick by PCR and / or blood serum for ELISA, based on the doctor's recommendations, specific immunotherapy is carried out.

The introduction of human immunoglobulin against tick-borne encephalitis is paid!

Free gamma globulin injected certain categories citizens and on the basis of a VHI policy under the program for the treatment of tick-borne encephalitis (be sure to contact the medical institution specified in the contract within 4 days after the bite).

The time during which specific treatment is possible, the period, the frequency of administration of globulin should be found out from the attending physician. The address of the point of medical care for encephalitis is indicated:

in the VHI policy;

on the stand in the laboratory.

The likelihood of a tick attack on a person depends on:

epidemiological well-being of the territory of residence;

profession associated with frequent stay in the forest, field;

the likelihood of visiting places that are unfavorable in terms of tick-borne infections.

Prevention of the consequences associated with a tick bite is based on:

vaccinations, but preventive measure, when a person is infected, it cannot be used;

specific immunotherapy is a therapeutic measure (administration of immunoglobulin only in case of infection or suspected infection after a bite);

health insurance to pay for possible treatment;

the use of special clothing and devices to prevent ticks from getting on the body;

the use of repellents, the destruction of ticks;

limiting the number of ticks in biotopes, places where people are likely to be.

Vaccination significantly reduces the risk of disease, it is shown to all people living in disadvantaged regions, and to persons professionally associated with the forest (drillers, geologists, surveyors, foresters). If desired, the vaccination can be given to anyone who is interested in it, in the absence of contraindications.

Primary vaccination is possible from the first year of a child's life, and then at any age. Adults can be vaccinated with domestic and imported drugs, children are better with imported ones. Six variants of vaccines from four manufacturers from Russia, Germany and Switzerland are available in Russia.

Tick-borne encephalitis vaccines produced in Russia:

The concentrated inactivated vaccine is indicated for use from three years and older;

Encevir (EnceVir), Russia, shown from the age of eighteen and older.

Vaccines against tick-borne encephalitis produced in Switzerland:

FSME-Immun Junior (FSME-Immun Junior), shown from one year to sixteen years;

FSM-Immun Inject (FSME-Immun Inject), indications are similar.

Vaccines against tick-borne encephalitis produced in Germany:

Encepur Children, shown from twelve months to eleven years;

Encepur adult (Encepur adult), shown from twelve years and older.

Two vaccination schemes: prophylactic and emergency:

Preventive vaccination provides protection against ticks during the first year, and after revaccination - for three years. Re-vaccinations are carried out every three years.

Emergency vaccination provides a short protective effect. Indication - urgent trips to regions unfavorable for encephalitis.

Vaccination is carried out after a preliminary survey of the patient for allergic reactions, clinical examination, thermometry. Persons with health problems are not allowed to be vaccinated. There are contraindications and restrictions.

In Russia, "Human Immunoglobulin Against Tick-Borne Encephalitis" is produced, produced by the Federal State Unitary Enterprise NPO "Microgen". The drug contains ready-made antibodies to viral encephalitis. It is administered intramuscularly for the purpose of treatment, usually after infection or at the risk of infection. Doses and frequency of administration can be obtained from your doctor.

Recommendations for insurance of costs associated with the treatment of tick-borne encephalitis

It is advisable to recommend insurance as an addition to vaccination or as the only measure in case of impossibility of vaccination. Insurance against tick-borne encephalitis is carried out as part of VHI - voluntary medical insurance. The payments are intended to compensate for the costly treatment of tick-borne encephalitis and other similar infections. When choosing an insurance program and an insurance company, you need to pay attention to:

availability of permits for the execution of VHI by the insured;

the cost of VHI services and the reputation of the insured;

availability of documents for the right to provide medical and preventive care or an agreement with a person authorized to provide such assistance on behalf of the insured;

24/7 free telephone line emergency advice.

Going into the woods or out of town, choose the right clothes light colors:

anti-encephalitis suit;

a jacket (shirt) with long sleeves and cuffs and trousers tucked into socks;

a hood that fits snugly to the head and protects the neck.

Every hour you need to inspect clothes from the bottom up for ticks. It is recommended to inspect the body every two hours, primarily the armpits, neck, groin, chest and head. It is worth avoiding or minimizing being in tall grass at the edge of the forest, along the paths.

Available for sale various fixtures to prevent ticks from getting on the body in the form of insecticide-impregnated mosquito nets, special shoes, clothes, and so on.

Recommendations for the use of means for repelling and exterminating ticks

For these purposes, you can use repellents and acaricides.

Repellents repel ticks and insects - these products are suitable for application to exposed parts of the body and clothing. Active substance- DEET (diethyltoluamide).

Preparative forms of repellents:

Ultraton (Ultraton) USA - lotion, aerosol;

Biban (Czech Republic) - aerosol;

DEFI-Taiga - solution, pencil, lotion, emulsion, aerosol, balm, cream, gel;

Off extreme - aerosol;

Gall-RET - aerosol;

Raptor - aerosol;

DETA-prof - aerosol;

Breeze-antiklesch - aerosol.

Acaricides (destroy ticks) - have only contact action. They should be used exclusively for processing the fabric of outerwear and anti-mite treatment of territories and premises! Modern acaricides are made on the basis of permethrin and alphacypermethrin:

Raftamid-taiga - an aerosol that can be used to treat an anti-encephalitis suit, dry it and wear it over underwear with long sleeves and pants. Acaricidal action lasts up to 10-15 days;

Picnic Antiklesch - aerosol, apply the same way;

Tetrix (concentrate) - a liquid suitable for processing change houses, produced in 0.25 l bottles and canisters of 1 l and 5 l;

Recommendations for the destruction of ticks in biotopes and places where people are likely to be

To prevent the spread of ticks, you should regularly:

mow the grass on the site (ticks guard the victim in the grass, usually at a height of 0.6 m, the maximum height is 1.5 meters; in a hungry state, ticks live from two to four years, according to some sources up to seven years; development from egg to adult individuals - imago takes two to three years or more);

In addition to ixodid ticks, the class of these insects has many other varieties. An army of arachnid harmful individuals lives with us almost everywhere: in a dwelling, on household plots, in forested areas. Are ticks dangerous to humans? What do they look like, how to find them? What to do if bitten by an encephalitis tick? How to provide first aid to the victim?

Attacking Varieties

These individuals do not differ in aggressiveness, but they can bring harm. Among them:

• Argas mites. They live in burrows, caves, cracks. They can settle in the crevices of village houses, attack people at night, however, episodes of daytime attacks have also been recorded. They are the causative agents of various infections: hemorrhagic fever or relapsing fever. The infection is transmitted quickly, within a minute, the disease progresses rapidly. If you are bitten by a tick of this type, you should immediately seek the advice of a medical institution.
• Gamasid mite. Mostly they bite birds, but if there are none nearby, they are able to attack people. They live in chicken coops or bird nests.
• Subcutaneous mite. This tick on the human body can live for a long time, while not impersonating anything. It feeds on dead cells. But with a decrease in immunity, they are able to penetrate deep under the skin, provoking various suppurations and rashes. Most often they affect the scalp and face. You can get infected with this tick household way or from animals.
• bed mite. The opinion of many people that this type of tick is capable of attacking is erroneous. Its danger lies only in the fact that it can provoke allergic diseases. It feeds on purely obsolete skin cells, does not consume blood at all.
• Barn mite. From the name it is already clear that he lives in barns and food storages. Feeds on cereals. Entering the human esophagus through dirty hands or products infected with it, can provoke various food poisonings.

However, forest mites bring the greatest harm to human health. Let's dwell on them in more detail.

Bites of forest ticks

They attack both animals and people, in most cases in forest plantations. Recently, however, ticks in the Moscow region are quite often found in park areas and squares. They hibernate in fallen leaves, but as soon as the snow cover disappears, they begin their hunt. The peak of activity is noted in the middle of spring, but they can attack a person and bite in the autumn. Forest mites are divided into two groups:

1. The infected are carriers of dangerous viral diseases.
2. Sterile - individuals that do not pose a danger to the human body.

The consequences of a tick bite in humans can be extremely dangerous, since these insects are carriers of many various diseases. Upon contact with the body, this insect may not bite immediately. Before suction sometimes takes several hours.

What does a forest tick look like

A small arthropod that resembles a small beetle. It has 8 legs, the body of the tick is covered with a shell. The length of the insect is about 4 mm. It is very difficult to see with the naked eye the blood-sucking parts of it (head and trunk), since they are very miniature.

Males are even smaller. A well-fed female can reach a size of about 2 cm, since she is able to drink blood from her victim 10 times her own weight, being hungry. What a tick looks like on the body can be seen in the photo given in the article.

Attention! The tick has no eyes, but it is excellently oriented in space thanks to a highly developed sense of touch and smell. Scientists were able to prove that the tick is able to feel its prey, even being at a distance of about 10 m from it.

How a forest tick attacks a person

There is an erroneous opinion: if a tick stuck into a person’s head or stuck on his neck, then he fell from a height, for example, from a tree under which the victim was or simply passed by him. This is far from being the case, because the insect never rises above 50 cm.

General information about bites

The severity of symptoms depends on the number of bites and the physique of the bitten. The most difficult to tolerate bites are the elderly, children, people suffering from chronic diseases, allergies.

The main symptoms of a bite:

• The body temperature rises.
• There is a headache.
• In some cases, itching may occur.
• The blood pressure goes down.
• The heartbeat quickens.
• A rash appears on the skin.
• The lymph nodes are enlarged.
• There is a general weakness.

The consequences of a tick bite in humans depend on the type of insect: infected (encephalitic) or sterile (uninfected). Much more dangerous bite encephalitis tick. The symptoms are very severe and extremely dangerous:

• Paralysis.
• Stopping breathing.
• Cessation of brain activity.
• Death.

If the victim was bitten by an uninfected tick, the diseases that may appear are of a slightly different nature:

• Suppuration of bite sites.
• Allergy of a different kind.
• Edema up to Quincke's edema.

It is impossible to understand by eye which tick has stuck.

Important! If you are bitten by a tick, treatment is on early stages help protect against more dangerous diseases.

Tick ​​bites: what they look like

Insect saliva contains a biologically active substance that has an anesthetic effect, so a person may not even suspect in the first hours that he was bitten by a tick. Only after this time can the first symptoms begin to appear.

Place of the bite of an infected tick: redness of the skin and swelling. They do not appear immediately, but after a while. If the spot expands in an annular pattern, immediate medical attention is required. This is the first symptom of Lyme disease.

What to do with bites

Tick ​​bite detected. What to do if the general condition worsens? In this case, the patient should be given an antihistamine to drink. It is better if these are Zirteks, Suprastin preparations.

How to remove a tick from the body

An insect on the human body is fixed extremely firmly. The fact is that his saliva acts as a cement composition. The proboscis is quite firmly glued to the skin. Therefore, the removal of the tick should be done carefully and extremely carefully. Recommendations for this procedure:

It is not recommended to smear the affected area with kerosene, gasoline and other liquids. If the insect crawls out of the wound, then after that it simply may not be accepted into the laboratory.

Diseases from tick bites and their symptoms

The consequences of a tick bite in humans are varied - from simple redness to severe and dangerous diseases:

• Encephalitis. The initial stage is very similar to the symptoms of a common cold. Incubation period can last up to 7 days. No examination can give an accurate analysis of the infection if 10 days have not passed since the bite. For accurate diagnosis, you need to present the insect itself for examination, but only alive.
• Lyme disease (borreliosis). This disease can be formed if the tick was a carrier of the spirochete virus. Symptoms may not appear immediately, but after a few months, this is usually: an increase in lymph nodes and aching joints.

Modern medicines are able to completely cure tick-borne infections with timely detection and proper therapy.

Important! Tighten with the extraction of the tick is not worth it! The longer he drinks blood from the victim, the greater the number of pathogens enters his body.

Signs of the development of encephalitis

According to experts, the symptoms of this severe and extremely dangerous disease begin to appear only after 10-14 days from the moment a tick bite was detected in the patient. What to do? Do not panic and needlessly worry. And an increase in body temperature and discomfort, especially in the muscles, can be interpreted as a protective psychological reaction to the fear of the victim. The formation of the disease takes place in several stages:

• Sudden and short-term manifestation of chills, after which the body temperature rises to 40 degrees. By clinical picture at this stage, the signs of the formation of encephalitis are similar to a flu attack.
• After some time, the victim observed: nausea and vomiting, severe headache attacks. At this stage, the symptoms resemble food poisoning.
• A day later, the patient begins to show signs of arthritis or arthrosis. Headaches pass, they are replaced by aches in the bones and joints. Motor activity is severely limited, breathing becomes difficult. The skin on the face and body turns red and swells, purulent masses are released from the lesion.
• Further, the symptoms only intensify, since at this stage the virus that has entered the patient's blood begins its destructive activity in the body, and the consequences can become irreversible.

Therefore, if you find that a tick has stuck into the body, then you need to immediately remove the insect. This can be done on your own or you can contact the sanitary and epidemiological station. There, doctors will be able to remove it and examine it. Only laboratory analysis is able to determine what type this tick is. Treatment, if it is prescribed, must be completed in full.

Important! Take any tick bite very seriously, as it can be encephalitic.

Signs of the development of borreliosis

This disease is diagnosed more often than encephalitis. The disease is extremely dangerous, very often occurs in a latent form. In chronic forms, it can lead to disability. The incubation period can last from several days to a month. The process of formation of borreliosis is divided into several stages of development:

• The first stage is a localized flow. A typical sign is reddening of a round shape on the skin. The tick bite site, as the disease progresses, increases in diameter, especially its peripheral edges, from 2 cm at the beginning to 10 cm or more at the end. The edges of the skin in the epicenter of the focus in comparison with healthy areas rise slightly. In the center, the skin becomes bluish, the immediate site of the bite is taken with a crust, then a scar forms instead. Lasts about 3 weeks, then slowly disappears.
• The second stage is disseminated, or, as it is also called, widespread. Symptoms begin to appear several months after the bite with CNS disorders, damage to the heart and joints, and pain in muscle tissues. Arise arthritis, encephalitis, myocarditis.
• The third stage is chronic. Formed in the complete absence of treatment. At this stage, there is a rapid defeat of the central nervous system with polyarthritis, multiple sclerosis, atrophy of the skin and other symptoms.

Forecasts are favorable with timely and proper treatment. The transition of the disease to a chronic form can lead to disability.

How is the process of infection with borreliosis

Treatment for tick bites

The first is removing the tick and examining it for the presence of the virus. After a confirmed diagnosis, the patient is prescribed complex treatment. In acute forms, the strictest bed rest is prescribed in combination with intensive therapy, the purpose and task of which is to reduce intoxication in the body and suppress the activity of the virus.

The patient is administered intramuscularly "Gammaglobulin". The sooner this drug enters the body, the faster the therapeutic effect will come. The agent acts for 24 hours, after which the patient's temperature drops to normal, the symptoms of encephalitis and meningitis decrease, sometimes disappear altogether.

To reduce the symptoms of poisoning, infusion detoxification treatment should be carried out. To do this, the patient is given fluids that help restore electrolyte balance, and glucocorticoids are also prescribed.

Antiviral medications

Within the territory of Russian Federation more commonly used:

• For adults and children over 14 years old - "Yodantipirin".
• For small children (up to 14 years old) - "Anaferon" for children.

Advice! If at the right time these drugs are not at hand, then they can be replaced by Cycloferon, Arbidol or Remantadin.

• The drug "Immunoglobulin" is advisable to use only in the first three days.

Emergency prevention - take a tablet of the drug "Doxycycline", but no later than 72 hours: for an adult - 200 mg, for a child aged 8 years and older - 4 mg per kilogram of weight. Small children and pregnant women are not recommended to use the drug.

Preventive actions

Most effective method prevention of diseases from tick bites - vaccination. Especially for people at risk - living in unfavorable areas or near forest belts.

On the territory of our country, six types of vaccine are officially used, and two of them are intended for children. It is best to graft in late autumn. However, there are also urgent vaccination schemes provided for emergency situations.

In the warm season, you can also be vaccinated, but with the condition that after vaccination, a person will not visit places where insects live for a month. The effect of vaccination will come only after the specified period. After this time, re-vaccination is done. Then you can get vaccinated every three years. If for some reason the period between vaccinations exceeds 5 years, then you will have to double-vaccinate again.

How to protect yourself from bites

First of all, you need to have a clear idea of ​​​​the places and areas where ticks can most often live:

• Favorable terrain for them - wet lowlands with trees and thick grass, ditches, forest edges, especially birch, ravines, coastal areas near water bodies. Moreover, it is on the edges and forest paths that there are much more of them than inside the forest.
• Trails and paths keep human and animal tracks - these are the most attractive places for ticks.

When going to such places on vacation, it is best to dress in light-colored clothes. Against its background, the clinging insect is easy to notice. Be sure to cover your head with a cap, scarf or panama. Every 2-3 hours, carefully examine the body, clothes, especially the head. Buy special creams, ointments and sprays, use them before visiting places where these dangerous insects are likely to live.

The first 2 diseases (tick-borne encephalitis and borreliosis) are the most common, the rest are diagnosed much less frequently. Some ticks can be carriers of several infections at once, and, as a result, infect a person with several diseases at once.

How does a tick bite

Female ticks can stay on the skin from several hours to a week, while males are able to stick for a short time, making small bites. Therefore, for example, if a person saw on his skin a tick that was not attached, but simply crawling, it is likely that the tick still inflicted a bite.

Where and when are you most likely to get a tick bite?

The greatest danger of contracting a serious disease from a tick bite is people living in endemic areas for diseases, as well as those who visit these areas during a special period - from May to mid-June and from late August to late September.

But the danger of being attacked by ticks persists throughout the warm season when visiting almost any forest area, parks and other areas where there is grass and shady shelters. You can even get a tick bite in your country house or in the adjacent territory of your private house, if the grass is not mowed there.

Maximum number of bites from infected ticks
registered annually in Siberia, the Urals and the Volga region. However, a considerable number of those bitten annually seek medical help in almost all regions of Russia, including the Crimea and the Caucasus.

What parts of the body do ticks mostly bite?

Ticks are localized in the grass mainly at a height of 30 cm, and cling to the legs of those who pass by. Most often, they accumulate on the grass along the paths, smelling the people passing here. Sometimes they climb shrubs and lower branches of trees.

Once on the human body, the tick begins to look for places with thin skin, which is easier to bite through, so most often it sticks in the area:

• groin,
• abdomen and lower back,
• armpits
• chest,
• ears and neck,
• scalp.

If a tick bite is suspected and for prevention purposes, it is these places that should be most carefully examined after visiting the forest and park.

What does a tick bite look like?

Signs of a tick bite in humans are sometimes limited to only a small reddish spot and swelling in the wound area, and after a few days the skin takes on a normal appearance. Under the influence of saliva and microtrauma caused by a tick oral apparatus, on the skin there is a slight inflammation and a local allergic reaction. There is no pain, but in some cases a slight itching may be present.

Seeking a doctor is necessary in any case, even if there are no negative reactions from the body. The course of the first stages of dangerous diseases is sometimes hidden, in addition, some diseases have a long incubation period. Only a blood test will confirm the absence of the disease.

Signs of an allergic reaction to a tick bite

An allergy occurs in response to tick saliva getting into the wound. The individual reaction of the body depends on the state of health in general. The consequences of tick bites are more severe in allergy sufferers, children, the elderly and people with weakened immune systems. You can remove a moderate allergic reaction with the help of antihistamines.

Common signs of allergies:

• weakness;
• drowsiness;
• aches in the joints;
• headache;
• nausea;
• dizziness,
• temperature rise;
• itching and rash in the area of ​​​​the bite and on other parts of the body.

With a strong individual allergic reaction, anaphylactic shock may occur, which is preceded by:

• difficulty breathing;
• hallucinations;
• angioedema (rapid and massive swelling of the face, throat, or extremities);
• loss of consciousness.

Anaphylactic shock can be controlled with the administration of prednisolone and adrenaline. If the symptoms after a tick bite indicate a severe allergic reaction, an urgent emergency call is necessary, otherwise a fatal outcome is possible.

Signs of the development of tick-borne encephalitis

The incubation period for tick-borne encephalitis can last from 4 to 14 days. During this period, the infected person does not have any external health problems. Then the temperature rises sharply to 38-39 ° C, the patient has a fever, appetite disappears, muscle and eye pain appears, nausea or vomiting, severe headache.

Then comes remission, during which the patient feels some relief. This is the second phase of the disease, during which the nervous system is affected. Subsequently, meningitis, encephalitis, paralysis may develop. If left untreated, death is likely.

The problem is that the signs of the disease in the initial stage are often confused with the flu and acute respiratory infections, so they do not go to the doctor, but self-medicate. When a high temperature appears after a detected or suspected tick bite, time should not be missed - a blood test and hospital treatment are necessary.

Symptoms of borreliosis

If a tick carrying borreliosis has bitten, the bite site takes on the appearance of a specific erythema, which gradually increases to 10-20 cm, and sometimes up to 60 cm in diameter. The erythema patch may be round, oval, or irregular shape. The victim may experience burning, itching and pain at the site of the bite, but more often the first signs are limited to erythema alone.

After some time, a saturated red border forms along the contour of the spot, while the border itself looks slightly swollen. In the center, the erythema becomes pale white or cyanotic. After a few days, a crust and scar form in the bite area, which disappear without a trace after about 2 weeks.

The incubation period before the onset of the first symptoms ranges from several days to 2 weeks. Then comes the first stage of the disease, which lasts from 3 to 30 days. During this period, the patient experiences muscle aches, headache, weakness, fatigue, sore throat, runny nose, stiffness of the neck muscles, nausea. Then, for some time, the disease can go into a latent form up to several months, during which the heart and joints are affected.

Unfortunately, erythema is often mistaken for a local allergic reaction, without giving it special significance. And the malaise during the first stage of the disease is attributed to a cold or overwork at work. The disease flows into a latent form, and openly declares itself after a few months, when serious harm has already been done to the body.

Signs of the development of other diseases

An increase in temperature to 38°C and above may indicate the beginning of the development of any of the tick-borne infections. It is important to remember that a symptom such as fever does not occur immediately after a bite. The incubation period of some diseases can last up to 14 days (ehrlichiosis, hemorrhagic fever), or up to 21 days (tularemia).

Against the background of a high temperature, the following symptoms may indicate the onset of the disease:

• heart palpitations and pressure surges;
• sore throat, tongue lining and runny nose;
• anorexia, nausea and vomiting;
• swollen lymph nodes and a rash on the face (typhus);
• nosebleeds, abdominal pain, diarrhea (tularemia);
• chills, sweating, clouding of consciousness, lower back pain (hemorrhagic fever).

After a tick bite, it is necessary to measure the temperature daily for 2 weeks and monitor the state of health: any changes that appear cannot be ignored.

First aid for a tick bite

You should also consult a doctor if a trace of a possible tick bite has been found on the skin or if the signs of infection of any of the tick-borne infections described above appear. If necessary, after the examination, the doctor prescribes an appropriate course of treatment with the use of anti-inflammatory and antibacterial drugs or recommends immunotherapy.

Taking antibiotics after a tick bite is not always justified. If it is impossible to immediately consult a doctor, for the purpose of emergency prevention, it is better to take immunomodulators (for example, iodantipyrine). Allergy sufferers can take antihistamines.

Blood-sucking mites are carriers of numerous infections and belong to the class of especially dangerous ones. Infection occurs directly through the bite of an arthropod. The most serious infections carried by ticks are encephalitis and borreliosis.

The peak of registration of bites falls on the first half of summer, but the activity of ticks is observed until late autumn. A tick can get caught on clothing and then make its way to exposed skin. Often penetration dangerous tick occurs through the sleeves, at the bottom of the trousers, in the collar area.

Tick ​​classification

In size, these representatives of arthropods rarely reach 3 mm; in general, the size of mites ranges from 0.1 to 0.5 mm. As befits arachnids, ticks lack wings.

Ticks are classified into two main groups:

• Sterile - those individuals who are not carriers of any infections;
• Infected ticks that are carriers of viral, microbial and other diseases (, encephalitis).

It is worth noting that most often ticks begin to bite in early spring and late autumn. Please note that not all ticks are carriers infectious diseases. Despite this, even a sterile tick can lead to serious consequences. That is why it is so important to know what to do in specific situation when attacked by a tick.

Tick ​​bites - the first signs in humans

As a rule, the first sign of a bite is the presence of an insect attached to the body of the victim. Most often, this is exposed to areas of the body hidden under clothing and places with a well-developed capillary system.

A tick bite is usually painless, and this fact goes unnoticed even after the tick has finished drinking blood and falls off the skin.

The first signs after a tick bite may appear after 2-4 hours. These include:

• headache;
• weakness;
• photophobia;
• drowsiness;
• chills;
• aches in the joints;
• pain in the muscles.

If redness occurs during the bite, this may be a normal allergic reaction. But red spots that have reached a diameter of 10-12 cm can be a symptom. May appear, both after 2 days, and after weeks.

Overly sensitive people may feel signs of a tick bite, such as:

• nausea;
• vomiting and indigestion;
• Strong headache;
• dizziness;
• wheezing breathing;
• hallucinations.

If you are bitten by a tick, measure your body temperature daily for 10 days! Its increase 2-9 days after the bite may indicate that you have contracted an infectious disease!

Symptoms of a tick bite

Most often, the first symptoms begin to manifest themselves 7-24 days after the bite. There were cases when a sharp deterioration in the condition was observed after 2 months. Therefore, health needs to be monitored.

If the tick has not been infected, then the redness and itching quickly pass without a trace, no other symptoms appear. If the insect was infected, then after the tick has bitten, signs such as general weakness, chills, drowsiness, body aches, joints, photophobia, neck numbness appear.

Please note that the affected area is painless, there is only a slight round redness.

The severity of symptoms may vary. How tick bites manifest themselves depends on the age, individual characteristics, general condition of the person, and the number of sucked insects.

The main symptoms of an encephalitic tick bite in humans:

• Body aches
• Increasing headaches,

If there are such symptoms, nothing can be postponed, you should immediately contact the clinic.

The earlier treatment is started, the better the prognosis. Therefore, it is important to vaccinate on time, insure against tick-borne encephalitis, so that injections with immunoglobulin and subsequent therapy are free.

What does a tick bite look like on a person's body

The tick is attached to the human body with the help of a hypostome. This unpaired outgrowth performs the functions of a sensory organ, attachment and bloodsucking. The most likely place for a tick to stick to a person from the bottom up:

• groin area;
• abdomen and lower back;
• chest, armpits, neck;
• ear area.

Bites can often manifest themselves in different ways. Let's look at the photo of what a tick bite looks like on a human body:

If, after removing the tick, a small black dot remains at the suction site, this means that the head has come off and must be removed. To do this, the affected area is treated with alcohol and the wound is cleaned with a disinfected needle. After removing the head, you need to lubricate the wound with alcohol or iodine.

Be sure to save the tick (put it in a plastic bag) so that you can test it in the laboratory and determine whether it was an encephalitis tick or not. The severity of the consequences for the bitten person or animal and further therapy depend on this.

It must be understood that a small tick bite can lead to serious health problems. So, encephalitis can cause paralysis of the limbs and lead to death.

If you are close to the city, contact the emergency room immediately, specialists will remove the tick without unnecessary risk. And there is a risk of crushing it during self-extraction, and if the crushed tick turns out to be infected, a large amount of the virus will enter the body.

The further course depends on how quickly the person reacted to the defeat. If he ignored the symptoms and did not go to the doctor, the prognosis is extremely unfavorable. The fact is that tick bites can manifest themselves only after a while.

Consequences for the body

A tick bite can cause a number of diseases in humans. Naturally, if you do not pay attention to this, serious consequences are possible.

Below is a list possible consequences tick-borne infections, in the form of lesions:

• nervous system-, encephalomyelitis, various types of epilepsy, hyperkinesis, headaches, paresis, paralysis;
• joints - arthralgia, arthritis;
• cardiovascular system - arrhythmia, jumps in blood pressure;
• lungs - a consequence of pulmonary bleeding;
• kidneys - nephritis, glomerulonephritis;
• liver - digestive disorders.

In severe forms of these infections, there may be a loss of the ability to self-service, a decrease in working capacity (up to disability of group 1), epileptic seizures and the development of dementia.

Diseases that can occur with bites

• Tick-borne encephalitis
• Tick-borne typhus
• Hemorrhagic fever

• Borreliosis. The causative agent of this disease are spirochetes, which spread in nature, including ticks. The disease proceeds in a chronic form, affects almost all organs and systems. In the treatment of borreliosis (Lyme disease), antibiotics are required! They are used to suppress pathogens. Lyme borreliosis is caused by a microorganism from the group of spirochetes.
• Tick-borne encephalitis. infectious viral disease transmitted through tick bites, characterized by fever and damage to the central nervous system. The consequences of a bite from an encephalitis tick can be very deplorable. In some cases, after suffering encephalitis, people become disabled.
• Tick-borne typhus. The rash of typhus is often initially called pink, although this first symptom appears only on fair skin. The next stage is the blanching of the rash, and later it turns red and dark again. In severe cases of typhoid, where hemorrhagic elements are visible, bleeding into the skin (petechiae) often develops.
• Hemorrhagic fever. The danger lies in severe and sometimes irreversible damage to vital organs. All people suspected of hemorrhagic fever are subject to hospitalization in the boxed department of the infectious diseases hospital.

Prevention

1. It is best to get vaccinated earlier, because after infection, the vaccine is prohibited. The vaccine is indicated for those who live in a disadvantaged region, professionally associated with the forest.
2. First of all, going to the habitat of ticks, you need to dress properly. Clothing should be with long sleeves, trousers, you also need to put something on your head, preferably a hood. Thermal underwear can be very convenient, as it fits perfectly to the body and does not allow the insect to crawl into secluded places.
3. Recovering to the area in which there are ticks, be as "armed" as possible, grab all the necessary things that will be needed in case of a tick bite.
4. When moving through the forest, stay in the middle of the paths, avoiding tall grass and bushes.

In the summer, there is a high probability of getting a tick bite. This topic must be treated with extreme scrupulousness. To date, tick bites in humans are quite common. This combination of circumstances can lead to serious consequences and even a threat to life. Going on a picnic in the forest, you must follow some rules of conduct there. If a tick is found, submit it for examination. These and many other questions will be discussed below.

ICD-10 code

Incubation period after a tick bite in humans

Infection occurs directly through the bite of an arthropod. It is the tick that is the carrier of many dangerous diseases for humans. There have been cases where infection occurred through gastrointestinal tract. No, you don't need to eat the tick. But cases of tick ingestion, thus, in the body were recorded, but only in animals. It is enough for a person to simply consume the milk of an animal that is infected. The incubation period in humans after a tick bite can last up to 30 days. In some cases, it is delayed for 2 months.

Most often, the first symptoms begin to manifest themselves 7-24 days after the bite. There were cases when a sharp deterioration in the condition was observed after 2 months. Therefore, health needs to be monitored. The incubation period is completely dependent on the blood-brain barrier. The weaker it is, the faster the disease will manifest itself, if any. You need to pay attention to all strange symptoms, including an ordinary headache. This will allow you to quickly identify the disease and eliminate it.

Symptoms of a tick bite in humans

If the bite was made by an infected tick, then the person has a risk of getting serious diseases. One of them is tick-borne encephalitis. With rapid development, it leads to damage to the nervous system and can lead to inflammation of the brain. Disability and death are not ruled out. The main symptoms after a tick bite begin to pester a person after a week.

Symptoms after a bite are very similar to the onset of an acute respiratory disease. A person feels a general malaise, body temperature rises, body aches appear. All this may indicate the presence of an infection in the body. A slightly different symptomatology is observed in the disease with borreliosis. The whole danger lies in the fact that there may not be any signs until six months. Then the bite site begins to turn red and all the above symptoms appear.

Vomiting, migraine, chills can act as auxiliary symptoms. The human condition is rapidly deteriorating. On the fourth day after the onset of the manifestation of the disease, sluggish paralysis may develop. Sometimes it affects the larynx and pharynx, because of this it becomes difficult for a person to swallow. There were cases when the reaction was so strong that there were violations in the work respiratory system and hearts. Epileptic seizures are possible.

What does a tick bite look like on a human?

Attachment of the tick to the human body occurs through an organ - the hypostome. It is an unpaired outgrowth capable of performing the functions of the sense organs. With the help of his tick is attached and sucks the blood. Most often, a tick bite in humans is observed in places with delicate skin, and looks like a red spot, with a dark dot in the middle. It is necessary to look for it on the abdomen, lower back, groin, armpits, on the chest and in the ears.

Allergic reactions may occur at the suction site. After all, flare saliva and microtrauma negatively affect skin person. Suction is painless, so a person does not feel it. The bite site is reddened, and has a round shape.

The bite of a tick, a carrier of the disease borreliosis, looks more pronounced. It is characterized by the appearance of a specific patchy erythema. The speck is able to change size and reach up to 10-20 cm in diameter. In some cases, all 60 cm were recorded. The spot has a rounded shape, sometimes it takes the form of an irregular oval. Over time, an elevated outer border begins to form, it acquires a bright red hue. In the center of the spot, the skin becomes bluish or white. The stain is somewhat reminiscent of a bagel. A crust and scar gradually form. After a couple of weeks, the scar disappears on its own.

Signs of an encephalitic tick bite in humans

It must be understood that a small tick bite can lead to serious health problems. So, encephalitis can cause paralysis of the limbs and lead to death. There is no need to panic ahead of time. You should be able to distinguish the symptoms and, if they appear, immediately consult a doctor. The likelihood of a favorable outcome is high if a person has signs of an encephalitis tick bite at an early stage.

The first thing is chills. A person thinks that he has an ARVI or flu. Therefore, he begins treatment on his own standard scheme but it doesn't help. An increase in temperature is added to the chill, sometimes its indicator is 40 degrees. At the next stage, a headache and nausea appear, sometimes all this is supplemented by vomiting. The person is still sure it's the flu. Severe headaches are replaced by body aches. Breathing gradually begins to be difficult, a person is not able to move normally. His face and skin are rapidly reddening. This indicates that the virus has begun its harmful activity. After that, irreversible processes begin in the body. Paralysis or death is possible.

Diseases after a tick bite in humans

A tick bite is safe, but only if the tick was not a carrier of any disease. The whole danger lies in the fact that most diseases manifest themselves over time. A person forgets about bites and continues to live as before. Meanwhile, the disease begins to actively progress, all this is accompanied by certain symptoms. Therefore, it is worth noting that after a tick bite, a person may develop the following diseases: tick-borne encephalitis, borreliosis, tick-borne acarodermatitis and dermatobiasis. The first two diseases are of particular danger.

Ehrlichiosis in humans from a tick bite

This is a dangerous infection that can enter the body after a tick bite. It can be cured with effective treatment. If it is not started, the person will die. Ehrlichiosis is caused by bacteria that are transmitted by a tick bite into the body. The likelihood of getting such a disease increases if a person is often in areas where ticks are spread. It is worth noting that a person can develop ehrlichiosis from a tick bite. However, not all ticks are carriers of the disease.

Borreliosis in humans from a tick bite

Lyme disease is caused by spirochetes of the genus Borrelia. The phenomenon is common on all continents, so avoiding infection is not so easy. A person who has Lyme disease is not dangerous to others. Bacteria, along with saliva, enter the skin of a person, after a few days they begin to actively multiply. The danger lies in the fact that from a tick bite a person can develop borreliosis, with further damage to the heart, joints and brain. Bacteria can live in the human body for years and gradually lead to a chronic form of the disease.

The incubation period is 30 days. On average, symptoms begin to manifest themselves after 2 weeks. In almost 70% of cases, this is reddening of the skin, the so-called erythema. The red spot can change its size and change. Ultimately, the bite site becomes covered with a crust, the skin may remain pale or become cyanotic. A red hill appears around the site of the lesion, all this visually resembles a donut. After a couple of weeks everything disappears. But the danger has not passed, after a month and a half, damage to the nervous system and heart may occur.

Tick-borne encephalitis from a tick bite

Tick-borne encephalitis is a natural focal infection that in most cases affects the human nervous system. This can lead to disability and even death. Infection occurs from a tick bite, which can provoke tick-borne encephalitis. People who like to spend a lot of time in nature are subject to such influence. They need to take extra care and constantly inspect their body for the presence of a tick.

The first signs after a bite can manifest themselves after a week. Sometimes it takes a whole month. First of all, chills begin, accompanied by an increase in body temperature and a feverish state. A person sweats intensely, he is plagued by a severe headache and body aches. If the symptoms do not manifest themselves for a long time, even slight muscle weakness can serve as a cause for panic.

It is necessary to seek help with a sharp increase in body temperature, strong head pain, sleep disturbance. Often the disease can cause hallucinations and convulsions. All these symptoms should be a reason to go to the hospital.

The consequences of a tick bite in humans

A tick bite can cause a number of diseases. Naturally, if you do not pay attention to this, serious consequences are possible. So, most often from a tick bite, a person can develop irreparable consequences. They arise due to untimely treatment of encephalitis, borreliosis, acarodermatitis and dermatobiosis.

• Encephalitis can lead to serious consequences. Often it affects the central nervous system and heart. A person may develop difficulty breathing, eventually paralysis appears. If treatment is not started on time, the victim may remain disabled or die.
• Borreliosis. The danger of defeat lies in the fact that the disease can be "silent" for six months. During this period, irreparable changes can occur in the body. So, borreliosis manifests itself in the form of erythema. Redness may appear at the site of the bite, progress over time and eventually disappear. The most terrible thing begins later, a month later, serious disorders of the central nervous system and heart develop. Lethal outcome is not excluded.
• Acarodermatitis. There are no consequences after such a defeat. A person can be bothered by local allergic reactions, but all this passes with time. The disease does not affect internal organs and systems.
• Dermatobiasis. The disease is especially dangerous for children. If the eggs from the abdomen of the tick begin to hatch in the body, a fatal outcome is possible. The child's body is not able to cope with this problem, even with high-quality treatment.

, , ,

Complications after a tick bite in humans

After a tick bite, various complications can develop. First of all, the central nervous system suffers. Perhaps the development of epilepsy, headaches, paralysis. The cardiovascular system is also affected. It is not excluded the appearance of arrhythmia, constant jumps in blood pressure. The lungs also suffer, pneumonia can develop, and as a result of this, pulmonary bleeding. Under Negative influence enter the kidneys and liver. In this case, after a tick bite, a person develops complications, in the form of nephritis and digestive disorders.

Encephalitis is of particular concern. At best, everything will end in chronic weakness. The body itself is able to resume after a couple of months. In severe cases, the process can take up to six months. In the worst case, a person will develop defects that will interfere with his normal life. Persistent changes in the body lead to epilepsy and disability.

, , ,

Temperature when bitten by a tick in humans

A sharp increase in body temperature a few hours after the bite indicates that the body responded to such an invasion with an allergic reaction. This happens due to the saliva of a sterile or infected tick getting under the skin. Therefore, when a tick bites, a person needs to constantly record the temperature, moreover, it is necessary to monitor the victim for 10 days. Body temperature must be constantly measured. Fever can manifest itself 2-10 days after the bite. This symptom indicates the beginning of infectious pathogenesis.

With tick-borne encephalitis, the temperature may rise 2-4 days after the bite. It lasts for two days and then normalizes on its own. Repeated increase is fixed on the 10th day. with borreliosis, body temperature does not change so often. With ehrlichiosis, fever appears on the 14th day. Moreover, it can be increased for 20 days. Therefore, for temperature indicators must be followed as a matter of course.

Redness after a bite

This symptom is characteristic of Lyme disease. The place where the tick is sucked is redder and resembles a ring. This can happen 3-10 days after the defeat. In some cases, there is a skin rash. Over time, the redness after the bite changes size and becomes much larger. For borreliosis, the appearance of erythema is characteristic. It is accompanied by severe fever, headache, and fatigue. Motor restlessness, muscle and joint pains are not excluded. Often there is swelling of the tonsils.

Over the next 3-4 weeks, the rash begins to gradually disappear and the stain may disappear completely. A person, as a rule, does not pay attention to all this. The danger still remains. So, after a month and a half, severe complications from the central nervous system may appear. Therefore, redness and, in general, tick bites must be monitored without fail!

Lump at the site of a tick bite

Often the human body responds negatively to the introduction of a tick into it. So, the bite site begins to turn red, in some cases a seal appears. What is causing all this and is there any danger in it. It should be understood that an ordinary allergic reaction can cause a bump at the site of a tick bite. It occurs due to the piercing of the skin with a proboscis and the ingress of saliva into them. Moreover, it is not necessary that the saliva be infected, even in a sterile form, it can provoke an allergic reaction. Itching, redness and slight induration are normal reactions of the body. But, it's not worth it to relax.

If the tick was submitted for examination, and it confirmed the absence of dangerous bacteria in it, there is no reason to worry. When a bump appears after a while, and the tick has not been checked, there is a reason to worry. You need to go to the hospital immediately. This may indicate an infection. Diseases caused by ticks have been described above.

A bump may occur due to improper removal of the tick. In some cases, the body of the tick is safely removed, but its proboscis remains in the skin. Therefore, the removal process must be monitored carefully. If a bump appears and additional symptoms in the form of fever and headache, you should immediately go to the hospital.

Diarrhea after a tick bite

Intestinal upset is not so common, but it can be one of the signs of a serious damage to the body. Each person is individual and even the bite of an uninfected tick can lead to a number of negative reactions. The site of the lesion may turn red, with time itching and a rash appear. The intestines are also able to react negatively after a tick bite, causing diarrhea.

This symptom is twofold. In one case, it may indicate the weakness of the body, in the other - to talk about its infection. Therefore, if negative symptoms appear, including intestinal upset, you should go to the hospital. Even if the person became better after a while. Many diseases carried by ticks begin to manifest themselves 2 weeks after the bite. During this period, the infection can develop in the body and lead to irreversible processes.

, , ,

Consolidation after a bite

Compaction after a bite may indicate an infection has entered the body. If this symptom appears along with redness, itching and a rash, you should immediately consult a doctor. This can be both improper removal of the tick, and the development of a serious disease. Often, after a bite, a seal forms, its development provokes an allergic reaction. Perhaps this is the most harmless thing that can happen.

Piercing the skin with its proboscis, the tick begins to stick. This process can cause itching, redness, and even rawness. Often, after removal, a seal appears. True, this symptom is not so harmless. It is likely that an infection has begun to develop in the human body. It could be encephalitis or borreliosis. You should immediately seek help from the hospital.

Often people incorrectly remove the tick itself. This causes its proboscis to remain in the skin. In this regard, the inflammatory process begins, there is a strong irritation and compaction. To cope with this problem, doctors will help.

Treatment after a tick bite in humans

The first step is to remove the tick. You can do this both on your own and by contacting the hospital. A live tick must be preserved and taken for examination. If it was killed during removal, it is worth placing it in a container with ice. In any case, the tick must be submitted for examination! After all, bites can cause a number of dangerous diseases. It is important that after a tick bite a person is correctly diagnosed with a disease and an effective treatment is prescribed.

The bite is treated with antibiotics. True, they are not always used to eliminate the causative agent of infection. To eliminate encephalitis, antibiotics are not used.

• Tick-borne encephalitis. First of all, a person needs to provide bed rest. It is desirable that it be at least a week. In the first three days, the victim should take human immunoglobulin. It is recommended to resort to the help of such means as: Prednisolone, Ribonuclease. Blood substitutes are also suitable, these are Reopoliglyukin, Poliglukin and Hemodez. If meningitis is observed, an increased dose of B vitamins and ascorbic acid is recommended. In case of respiratory failure, intensive ventilation of the lungs is used.
• The treatment regimen for borreliosis is somewhat different. The first step is to hospitalize the patient. At the stage of manifestation of erythema, he should use Tetracycline. Bacteriostatics play a special role in the treatment. It can be Lincomycin and Levomycetin. If a neurological syndrome is observed, then it is stopped by intravenous injections of bactericidal antibiotics. It can be Azlocillin and Piperacillin. The water balance is restored by means of blood substitutes such as Reopoliglyukin and Poliglukin

Where to go for symptoms of a tick bite in humans?

When bitten by a tick, you need to follow a special algorithm. The first step is to remove the tick. After that, it is handed over to a special accredited laboratory. This will allow him to identify the presence of infectious agents. The study is performed by PCR, directly in the body of the tick. A person needs to donate blood to detect antibodies. After all, bites can cause serious consequences. The victim is recommended to undergo a course of treatment based on the results of laboratory tests. When symptoms of a flare bite appear in a person, you need to know where to go.

Where can you take a tick and how to check it. It is necessary to find a hospital that does such research. The address of laboratories and phone numbers can be found on the Internet. Just visit the Ukrpotrebnadzor website. In fact, ticks should be taken in every hospital that has a laboratory. Most importantly, the study is completely free! This information is recommended to be corrected. The results are provided on the day the tick is taken or the next day.

How to treat a tick bite in humans?

If a tick is found on the body, it must be removed immediately. An experienced specialist can help with this. In the hospital, the tick is immediately submitted for examination, because a tick bite in a person can provoke the development of serious diseases, so you need to know how to treat the affected area. In an outpatient setting, a person is recommended to use immunoglobulins. The most commonly prescribed remedy is Rimantadine. It is taken for 3 days, one tablet in the morning and in the evening.

At home, the tick is removed with oil. It is necessary to drop a lot of it on the head of the tick. Alcohol is also used for these purposes. After 15 minutes, you can start removing. In most cases, the tick crawls out on its own. It is much easier to remove it this way, just use tweezers and pull out the tick in a circular motion. The bite site is recommended to be treated with hydrogen peroxide. Further advice can be obtained from the hospital. Usually, the site of the lesion is not treated with anything else.

Tablets from a tick bite in humans

If there is a risk of a person developing encephalitis or the diagnosis has been confirmed, start taking human immunoglobulin. It can be Prednisolone and Ribonuclease. Blood substitutes are actively used, such as Reopoliglyukin, Poliglukin. All these tablets from a tick bite do not give infection, spread throughout the human body and lead to serious lesions in the body.
