SOME ASPECTS OF THE EPIDEMIC AND EPIZOOTIC SITUATION OF TRICHINELOSIS IN THE NOVOSIBIRSK REGION
The aim of the work is to study some aspects of the epidemic and epizootic situation of trichinelosis in the Novosibirsk region. Materials for research were data on the incidence of people (in absolute terms and per 100 thousand population) from 2001 to 2015, obtained in the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Well-being in the Novosibirsk Region. The materials of the State reports "On the sanitary-epidemiological situation and compliance with the legislation in the field of consumer rights protection and human well-being in the Novosibirsk region" for 2007-2015 were analyzed. The standard statistical data processing was using computer program called Microsoft Excel. It was revealed that trichinosis was registered almost every year in the Novosibirsk region over the last 15 years. The incidence rate of the population ranged from 0.04 to 1.93 and averaged 0.39 per 100000 population. The average annual rate of decline in the incidence rate during the studied period was 4.5%. The dynamics of the manifestation of the disease in the city of Novosibirsk and in the whole region is very similar. This disease is registered in 15 administrative districts of the region from 30. Distribution of trichinelosis in the region is uneven. Outbreaks of trichinelosis were most often detected in the Suzun, Novosibirsk and Kochkovsky districts. The maximum number of cases per one outbreak (26 people, or 159.5 per 100000) was noted in the Kochkovo region. In 65.1% of cases, the cause of infection was the consumption of pork, almost 2 times less often - 30.3% - meat of wild animals and dogs, in 2 cases (4.65%) -the cause was not identified. Among wild animals in the Novosibirsk region, the most dangerous for trichinella was the badger (18.6% of cases). In most cases, infection of people with trichinelosis occurred when meat and meat products of local origin were used (43 cases), and only 5 cases of invasion were imported. According to the veterinary and sanitary examination for 2007 - 2015 in markets, meat-packing plants, slaughter houses and personal farmsteads of citizens in the Novosibirsk region, trichinella larvae were found in 67 carcasses of pigs, 5 carcasses of badgers and one carcass of wild boar. In one case, the source of trichinosis invasion is not established.
