Abstract

The aim – to establish of spatio-temporal features of HFRS manifestations in the territory of the Privolzhsky Federal District (PFD) in 2012–2014.

Materials and methods. Used were materials on the HFRS incidence in 2009–2014 of the Rospotrebnadzor Administrations and the Centers of Hygiene and Epidemiology in all constituent entities of the PFD.

Results. In 2012–2014 HFRS incidence was 80% of the total one of natural focal infectious diseases in the PFD, the absolute number of HFRS cases was 18850. Carried out was epidemiological zoning of the PFD territories as regards HFRS.

Conclusion. It was found that in 2012–2014 the greatest epidemic activity of HFRS natural foci was observed in the zone of deciduous forests, where the total number of cases was 9515 (54.3%). In the zone of southern taiga and middle taiga forests, it was 4925 (25.9%), in the steppe and forest-steppe landscape zones – 3778 (20%). PFD territory was divided into 3 groups, which differ in the level of potential epidemic hazard. To the first group assigned are the Republic of Bashkortostan, Tatarstan, the Udmurt Republic. The second group consists of Penza, Samara, Orenburg, Nizhny Novgorod, Saratov, Ulyanovsk Regions, Perm Region and the Republic of Mordovia. The third group includes the Kirov Region, and Chuvash Republic. By the example of the Saratov Region shown is heterogeneity of PFD subjects according to the degree of HFRS potential epidemic hazard.
