[The prognosis for the opisthorchiasis situation in an area influenced by hydraulic engineering works].

Basing on the materials of many years observation, literature and their own data, the authors consider expert prognostication methodology in regard to opisthorchiasis in hydro construction regions as exemplified by the Shidertinsk focus and Irtysh-Karaganda canal. Analysis of prognostication signs and alterations connected with them showed that relatively satisfactory situation concerning opisthorchiasis for 10-year period of channel exploitation was provided by measures aiming at water bodies protection, by changes in ichthyofauna, and by breaking the connection of water voles with fish. Further prognosis puts you on guard because of releasing a strict sanitary regime in coastal region due to opening the channel for population and fishery development.
