Chronological and chorological features of the epizootic process of echinococcosis in the conditions of the novosibirsk region

The article discusses some aspects of the epidemic and epizootic situation of larval echinococcosis in the Novosibirsk region. It has been established that the region is unfavorable for echinococcosis of farm animals and humans. A retrospective analysis of the long-term dynamics of infection of farm animals indicates the uneven development of the invasive process with a significant downward trend. The average annual rate of decline was 13.9 %. For the period from 2009 to 2020 the average infection of farm animals with the echinococcosis pathogen was (0.58 %), while this indicator in cattle and sheep does not have significant differences - 1.16 and 1.15 %, and in pigs it is registered at the level of 0.36 %, which 3 times lower than in ruminants. Long-term observations of the dynamics of the incidence of agricultural animals with echinococcosis in space indicate that, against the background of a significant decrease in the overall incidence of animals in the region, the mosaic pattern and dissemination of invasion increases. The epidemic situation is characterized by significant fluctuations in incidence from 0.04 to 0.75 per 100 thousand of the population and has an unreliable downward trend. The average long-term incidence rate of the population for the analyzed period (1999-2020) was 0.265 per 100 thousand, which is 2 times lower than the same indicator in the Russian Federation (0.365).
