Abstract

The high significance of the problem of hemorrhagic fever with renal syndrome (HFRS) is associated with the scale of spread, damage to persons of active age, a long period of reduced working capacity and high economic damage. The work presents an assessment of biological contamination by natural - focal viral infection - HFRS in the Re-public of Bashkortostan (RB). The most active foci are associated with linden forests, which prevail in the republic. The work shows the dynamics and features of infection. Analysis of the geoecological state of the territory according to HFRS showed that in the territory of most regions of the republic there are natural-focal infections of HFRS. There is an increase in infection of rodents with the HFRS virus, so in 2016 it was 5.0 %, and in 2019 - 16.2 %. The increase in the incidence of the population has characteristic epidemiological signs for the territory of RB, and the increase in high-risk areas indicates trends in the expansion and activation of foci of infection in them. At the same time, there is an increase in incidence, and infection in 50 % of cases occurs when visiting forests. In the capital of Bashkortostan - the city of Ufa, which is located in the natural zone, the incidence of HFRS is almost 50 % of the entire territory of the republic. In connection with climate changes, the diversity of environmental aspects of natural-focal infection of HFRS should be more widely assessed to counter their spread and measures to reduce this dangerous disease in the RB should be significantly strengthened.
