104 cases of Crimean hemorrhagic fever (CHF), including 9 lethal (8.6 %) were registered in the Volgograd Region in 2000-2009. Dynamics of human incidence and its association with the level of infection in the main carrier and vector - H. marginatum tick were demonstrated. The expansion of this species habitat resulted in the natural focus borders extension. The data presented in the article allowed to make a conclusion that persistent actively functioning natural focus of CHF had been formed in the territory of the Volgograd Region. The epicenter of this focus is situated in 2 South-Western regions - Kotelnikovsky and Oktyabrsky, - and with neighboring administrative territories and green belt of the Volgograd Southern regions being actively involved in the epidemic process.
