title: [An opisthorchiasis epidemic in Ukraine].
abstract: Based on the parasitologic evaluation of 3926 individuals in different climatic and geographic areas of Ukraine it has been ascertained that levels of affection of people with opisthorchiasis depend upon natural as well as social conditions, age of the examinees (but not sex of those infected), remoteness from riverbeds. It has been shown that high levels of contamination of soil with eggs of helminths and cysts of intestinal protozoans in those foci of opisthorchiasis having very high incidence rates of this invasion make for formation in the population of multicomponent intestinal parasite cenoses.
