The epizootic situation of avian influenza in the Kaluga region

Abstract

The article discusses the problems associated with increased virulence of strains due to the high representativeness of the sample of susceptible organisms, the spread of avian influenza and its natural reservoirs. Currently, avian influenza virus strains are divided into HPAI (highly pathogenic) and LPAI (low pathogenic). Registered outbreaks among wild and domestic birds and cases of human infection with influenza viruses of subtypes H5N8, H7N9 and H9N2 indicate an active mutation of the virus and the appearance of “aggressive” strains that can infect not only poultry, but also humans. This article analyzes the current epizootic situation of avian influenza in the Kaluga region for 2022-2023.
