Анализ заболеваемости Крымской геморрагической лихорадкой в Российской Федерации в 2017 г. и прогноз на 2018 г.

This paper presents the analysis of Crimean hemorrhagic fever (CHF) morbidity rates in Russia in 2017; summarized are the results of epidemiological survey of the territory of the natural CHF focus in the south of the European part of Russia, discussed are the results of genetic typing of CCHF virus isolates. In 2017, the Russian Federation reported 78 cases of CHF. Decrease in the incidence of CHF occurred in the Volgograd Region, Stavropol Territory, Astrakhan Region, Republic of Kalmykia, and Rostov Region. For the first time since 1967, CHF case has been identified in Crimea Republic. It is expected that the level of epizootic activity of CHF natural focus in Russia in 2018 will be at least equal to 2017. In case of favorable for Ixodidae ticks weather and climate conditions of the winter 2017–2018, as well as untimely acaricidal treatments, the number of Ixodidae ticks may increase, which along with the high scale of CCHF virus infection in ticks, will contribute to the increase in CHF incidence.
