EPIDEMIOLOGICAL CHARACTERISTICS OF A FOCUS OF TICK-BORNE ENCEPHALITIS IN PRESAYAN (IRKUTSK OBLAST)
Abstract
The following peculiarities were exposed in the contact of the population with the natural focus of tick-borne encephalitis in the territory of the forest belt of Presayan: For the population of settlements belonging to lumbering enterprises, the daily living factor lay at the basis of this contact; for the population of settlements belonging to the chemical-lumbering trusts the industrial factor played a significant role; however, its significance was spread to all the groups of the population, which specified the approximately similar conditions of contact with the focus for the entire population. It is expedient to differentiate the system of prophylactic measures in respect to the inhabitants of populated points of different types: For the settlements belonging to the chemical-lumbering trusts they should include the compulsory general vaccination of the population and the creation of tick-free zones around the populated points; for residents of the settlements belonging to lumbering establishments, along with the mass immunization of the population, it is necessary to carry out tick exterminating measures at the sites which are most frequently visited by the inhabitants in the performance of their everyday tasks. A correlation was revealed between immunological indices (based on the complement fixation reaction) and the zoo-parasitological indices of the intensity of the natural focus (numerical strength and virus carrying ability of the ticks in nature) in various years.
