ABSTRACT
The paper presents data of the long-term (1975-1994) study of Q fever in Carpathian region [correction of Forecarpathia] (Ivano-Frankivs'k and Chernivtsi provinces) and dynamics of epidemiologic manifestations of this disease during the recent years. It is shown that after Q fever outbreaks in 1975-1977, people sick for it have been recorded sporadically, and a considerable decrease of epidemiological manifestations of Coxiella burnetii circulation is observed in the late years. This is accompanied by the decrease of the immune stratum among the population from 10.1% to 1.6-2.8%. In the authors opinion there is the interepizootic period now when the agent population remains in the phase of reservation that requires devoting much attention to the future appearance of its epidemiologically dangerous variants. The expediency of the purposeful examination of the profile therapeutic patients for Q fever and a necessity of special study of the chronic form of this infection are emphasized.
