Assessment of the epizootic situation of avian influenza in the North Kazakhstan region

The purpose of research is to study the spread of avian influenza in the North Kazakhstan Region of the Republic of Kazakhstan, as well as to determine the risk zones for this epizootic. The studies were carried out in 2019-2022 at the Department of Non-Contagious Diseases of Agricultural Animals of the State Agrarian University of the Northern Trans-Urals, as well as at the State Institution "Petropavlovsk City Territorial Inspectorate of the Committee for Veterinary Control and Supervision of the Ministry of Agriculture of the Republic of Kazakhstan" in cooperation with the veterinary inspectorates of the North Kazakhstan Region. In order to study the frequency and monitoring of avian influenza, a retrospective analysis was carried out based on the reports of the veterinary stations of the region, veterinary departments and veterinary inspectorates of the region. The following factors were taken into account when analyzing the risk zones for the occurrence of an epizootic of avian influenza: climatic, geographical, environmental, and anthropogenic. In the North Kazakhstan region of the Republic of Kazakhstan over the past 10 years, for the first time an outbreak of avian influenza was noted in 2010 (in 3 districts), then in 2020 (12 outbreaks) and 2021 (1 outbreak). In 12 districts and 54 settlements of the North Kazakhstan Region, outbreaks of avian influenza in 2010-2021 contributed to the warm, relative to the average seasonal temperature, spring-summer and summer-autumn period; in 6 districts, including 36 settlements, poultry became infected in reservoirs with camping and nesting sites for migratory waterfowl and semiaquatic birds. Areas of increased risk of avian influenza epizootics are 9 out of 14 districts of the North Kazakhstan Region (64.2 %): Ualikhanov, Akzhar, Magzhana Zhumabayeva, Mamlyutsky, Tayynshinsky, Ayyrtau, Yesilsky, Kyzylzharsky, Akkayynsky.
