What is it?

By tick-borne infections are those diseases that a person can become infected through the bite of ticks. To date, five of medicine known infections:

  • tick encephalitis (pathogen — a virus of tick-borne encephalitis);
  • tick-borne borreliosis (disease Lyme) (pathogen — spirochete genus Borrelia);
  • Human granulocytic ehrlichiosis (exciter— Intracellular parasite Ehrlichia phagocytophila);
  • Human monocytic ehrlichiosis (pathogen — an intracellular parasite Ehrlichia muris);
  • Human monocytic ehrlichiosis (pathogen — an intracellular parasite Ehrlichia chaffeensis).

Of these the most common tick-borne infections — encephalitis and borellioz.

Sources of infection

Carriers of this infection — ticks — small arthropods without wings and antennae. Body they rise, is not divided into the head, breast and abdomen. Ticks are soft and hard (Ixodes). Just last have a nasty habit of sucking the blood of humans and simultaneously infect his infectious diseases. We iskodovyh mites have my favorite places: they prefer to hold on to the scalp, ears, elbows and knees, hands and feet. After attachment to the host may take 12 hours before mite will begin to suck blood. It is interesting that the person bitten by an infected tick, do not always get sick. Here the time factor is important. The longer mite drinking the blood, the more it stands out from the saliva that contains pathogens, and the greater the chance of infection. 24 hours spent with a mite, a chance to pick up the disease — 80%. I own infected insects do not develop the disease, but having caught one, they are carrying the pathogen life.

What way?

Recognize the tick-borne infection is difficult. After the incubation period (time from infection to the appearance of bright symptoms) in each disease yours: from tick-borne encephalitis — a month, with ehrlichiosis — about two weeks, with borreliosis (symptoms may not be at all) — from 2 to 30 days. The only solution: after the tick bite suspicious every day for at least a month to closely monitor their health. Measure temperature, and inspect the wound at the slightest indisposition — quickly run to the doctor. The best option — to visit infectionist immediately after the bite, and preferably withoffender-mite.

Diagnostics

If the patient went to a doctor in the first three days after sucking mite doctor take an insect on the survey, find out whether it some infection. It is desirable that the mite was intact, not poisoned by household tools and alive. If the tick is missing or dead, the doctor takes blood from a vein for research on the immune bodies to the virus of tick-borne encephalitis, and to Borrell Ehrlich — linked immunosorbent assay, or PCR analysis.

Emergency Assistance

Treatment should begin immediately after the detection of the infectious agent, without waiting for the development of the disease. To kill Borrelia and Ehrlichia infectious diseases doctor antibiotics are prescribed to patients. Against tick-borne encephalitis is assigned a special immunoglobulin.
