[Population migration and the epidemic process in opisthorchiasis].

A correlation between opisthorchiasis epidemic process and population migration is reviewed at the third stage of the migration process (the formation of the migration flow, resettlement as such, and settlement of migrants in a new place) in view of the prevention of infection in conditions of the population migration. The endemic situation in the areas between which there is population migration is considered as the initial point. A simplified method for the calculation of the number of infected persons among the migrants from the endemic territories is described.
