What is it?

Lyme borreliosis, or disease Lyme— An infectious disease transmitted by ticks.

The causative agent of Lyme disease — a type of Borrelia (Borrelia burgdorferi), from the family of Spirochetaceae. This — the only kind of Borrelia, pathogenic to humans and is widespread in the temperate zone.

In Russia you can get infected with Lyme disease after a tick bite in the forests of the Leningrad, Tver, Yaroslavl, Kostroma, Kaliningrad, Perm, Tyumen regions. In the Urals, Western Siberia and the Far East ticks that carry Lyme disease are found in the pastures. Depending on the season, the probability of disease after the tick bite varies from 5 to 90%.

What's going on?

Infection occurs through the bite of an infected tick. Borrelia tick saliva enter the skin and propagated for several days, after which they spread to other areas of the skin and internal organs (heart, brain, joints, etc.). Borrelia for a long time (years) can be stored in the body, causing a delayed onset of the disease, chronic course disease or refunds borellioz after apparent recovery.

What is shown?

The bite before the first symptoms can be from 2 to 30 days, on average — 2 weeks. A characteristic feature of disease onset in 70% of cases is redness of the skin at the site of the bite. Red Spot has gradually increased, reaching a 1-10 cm in diameter, sometimes up to 60 cm or more. Spot shape is round or oval, rarely wrong. The outer edge of a red inflamed skin, a few rising above the level of the skin. Over time, the central part of the spot fades or becomes cyanotic hue creates a form ring. In place of the tick bite, the center spot, you can first see the crust, then wound scars. Stain persists without treatment 2-3 weeks, then disappears. Through 1-15 months develop signs of damage to the nervous system, heart and joints.

Diagnostics

Great luck to be considered a diagnosis of Lyme disease at the stage of cutaneous manifestations. Unfortunately, often disease possible suspect it's too late, when fully operational apparent damage to internal organs. Confirm the diagnosis of Lyme disease is possible by means of a special blood test. These studies are carried out in specialized laboratories for infectious hospitals.

Treatment

Treatment of the disease Lyme conducted at the Infectious Diseases Hospital, where, first of all, therapy is aimed at the destruction of Borrelia. Without such treatment, the disease progresses, becomes chronic, and in some cases leads to disability. Been ill are under medical supervision for 2 years and examined at 3, 6, 12 months and 2 years. The bite of a tick next day should come to an infectious diseases hospital with a remote mite for his research on the presence of Borrelia. In order to prevent Lyme disease after being bitten by an infected tick doxycycline is recommended to take 1 tablet (0.1 g), 2 times a day for 5 days (children under 12 are not assigned). However, before taking the antibiotic should consult a doctor — a drug contraindicated! In Moscow, the Institute of Rheumatology, there is a special group to study Lyme disease [tel. (495)114-3429].
