[The structure of the geographic range of opisthorchiasis and the tasks in controlling this invasion]. / Struktura areala opistorkhoza i zadachi bor'by s invaziei.

ABSTRACT

Our own investigations in the Yenisei, Ob, Dnieper, Northern Dvina river basins and the analysis of the literary data served as the basis for establishing the relationship between the area of the pathogen dissemination and the area of opisthorchiasis distribution (the map scheme is attached). 4 degrees of endemicity characterized by quantitative indices of general affection, children's infestation, the invasion intensity and manifestation have been suggested as a criterion for division of territories into regions. The map of 3 territories in the Dnieper River basin (the Ukraine) most unfavourable for opisthorchiasis is presented. According to the endemicity, differential anti-invasion goals and measures are suggested.
