[Features of the sanitary-educational work in opisthorchiasis under conditions of migration pressure in an endemic region].

Under migration pressure, sanitary educational work is ineffective in the endemic area: newcomers' awareness of opisthorchiasis does not improve as their residence prolongs, the number of persons who recognize the harm of eating of raw fish and meat is increased. Hygienic education of newcomers is late and done only among a part of their contingent. Its unconvincing character is confirmed by late referral of those infected for being treated and struck off the register. Attention to the local population is being relaxed, which determines the low level of knowledge of what measures should be also made to prevent infection in this contingent which is an additional channel of information for new comers. The established epidemic situation in the opisthorchiasis-endemic area is largely determined by the fact that medical specialists know this problem badly.
