Epidemiologic Characteristics of Combined Natural Focus of Lyme Bоrreliosis and Tick-Borne Encephalitis

Abstract

Epidemiologic patterns of spread of TBE and Lyme Borreliosis in the Kemerovo region within 23 years (1993 - 2015) have been studied. It has been established that sickness rate of TBE has reduced while sickness rate of Lyme Borreliosis has increased. Risk groups and risk areas of distribution of tick-borne infections have been detected. Borrelia DNA has been detected in 35,46 ± 6,26% of ticks, TBE virus antigen has been detected in 2,2 ± 0,28% of ticks. Sickness rate of tick-borne infections and rate of detection of infected ticks differentiate in different areas of the region which therefore should involve differential approach to organization preventive measures.
