[The problem of opisthorchiasis in Ukraine and current approaches to its treatment].

The opisthorchiasis epidemiological situation in Ukraine and the Sumy Region that has the largest natural focus of invasion has been analyzed. Its morbidity rate is 21.6 per 100,000 population, which is more than 20 times greater than that in Ukraine.

[The epidemiological efficacy of opisthorchiasis control measures in Dnieper River basin foci].

The authors assess the epidemiologic efficacy of wide-scale antiopisthorchiasis measures taken in the basin of the Dnepr River in 1984-1990. The structure of the population morbidity and the time course of this morbidity under the effect of a complex of measures taken were analyzed in low-, medium, and highly-endemic foci of the disease. Hygienic education and adequate detection and treatment of the invaded subjects were found to be the principal factors contributing to sanitation of the population.

[Opisthorchiasis at left Dnieper watersheds].

Present state of opisthorchosis infestation in the Dnieper watershed (rivers Vorskla, Psyol, Khorol, Sula, Seym, Snov, Desna water basins), situated in the Sumy, Chernigov, and Poltava regions of the Ukraine, is assessed. 7909 humans from 37 villages, 94 cats, 1134 carp fishes, 20013 mollusca and 30 soil samples were screened for the presence of Opisthorchis eggs. Opisthorchosis foci with an over 36% infection rate of population remain in the watersheds of the Dnieper left confluents (rivers Desna, Seym, Vorskla and Khorol).
