[The spread of the principal socially important parasitic disease on the territory of the Chukot Autonomous Okrug (ChAO)]. / O rasprostranenii osnovnykh sotsial'no znachimykh parazitarnykh boleznei na territorii Chukotskogo Avtonomnogo Okruga (ChAO).

The paper provides the examination findings of helminthiases in the population of the town of Anadyr, the settlements of Kanchalan, Krasneno, and in the reindeer-breeding teams of the Anadyr District, CAD. The children infected with enterobiasis were shown to amount to 15.1 to 22.9%, diphyllobothriasis was detected in 12.9 - 33.7% of the examinees. Single cases of ascariasis were revealed. Analysis of 232 cases with echinococcosis demonstrates that the infection is prevalent over the whole Chukotka territory. Infection with Echinococcus multilocularis is more common in the indigenous population in the north-east of the District and that with Echinococcus granulosus in the central and northern regions. High extensive and intensive parasitic contamination rates of environmental objects, such as soil, sewage, household appliances, fish, etc., were noted, indicating a constant risk for Chukotka population's infection with parasites.
