Features of the dynamics of hemorrhagic fever with renal syndrome incidence in the Republic of Bashkortostan

Abstract

It was established that 17008 HFRS cases were reported in 53 (out of 54) administrative districts and 12 cities (out of 14) of the Republic of Bashkortostan in 2009-2018. The most intense epidemiological situation (a long-term incidence rate of 48,5 per 100 thousand of the population) was observed within the boundaries of the forest-steppe landscape zone, where. more than 86 % of all cases of infection are recorded of the Republic of Bashkortostan in 2009-2018. The share of infections among the urban population was 64.0 %, the rural one – 36.0 %. In the long-term aspect, according to the conditions of HFRS acquisition, short-term visits to the forest area prevailed – up to 80 %, in household settings – up to 14 % of all cases of the disease. Seasonal increases in the incidence of HFRS take place in May-June – up to 15 % and in September-December – over 46 % of the annual incidence. The presence of synchronicity in the dynamics of HFRS morbidity in rural and urban populations within the boundaries of the administrative district was detected. It has been substantiated that in order to reduce the level of HFRS morbidity among the rural and urban population, it is necessary to provide for an increase in the volume and frequency of preventive (anti-epidemic) measures in the vicinity of rural settlements, regional centers, urban-type settlements and large cities located near forests, within the boundaries of the entire area of the administrative district.
