[The epidemiological-epizootiological subdivision of the nosogeographic range of trichinosis].

The prevalence of trichinosis was analyzed among human beings and animals in Moscow Province over 50 years (1946-1996). A total of 7022 domestic, synanthropic, and wild carnivorous animals were incompletely helminthologically dissected. Enzyme immunoassay revealed diagnostic Trichinella antigen antibody titers in 45.4% of 544 examinees during outbreaks and at their intervals, as well as in 0.58% of domestic pigs of different property forms. Trichinella larvae were found in domestic pigs (0.13%), dogs (12.3%), cats (12.9%), hunting and fur-bearing (wild boars (2.0%), wolves (38.8%), red foxes (32.0%), raccoon-like dogs (20.0%)) animals and rats (2.4%). Criteria were developed and epidemiological and epizootic division of the districts near Moscow was made. Three unfavourable (hyperendemic, mesoendemic, hypoendemic) and one favourable areas were identified. A trichinosis control programme was worked out.
