[The prognosis of the diphyllobothriasis situation in water reservoirs under construction (the Adyche and Sakhalin reservoirs)]. / Prognozirovanie situatsii po difillobotriozom na proektiruemykh vodokhranilishchakh (Adychanskoe i Sakhalinskoe).

The investigations conducted in the construction area of Adyche and Sakhalin water reservoirs made it possible to work out the prognosis for the changes in the situation on diphyllobothriasis. In the area of Adyche water reservoir the population invasion with D. latum is likely to increase, while in the area of Sakhalin water reservoir the situation on D. klebanovskii sp. no. will remain unchanged.

[The spread and evaluation of the potential for the formation of new foci of opisthorchiasis and diphyllobothriasis in the Yenisei basin]. / Rasprostranenie i otsenka vozmozhnostei formirovaniia novykh ochagov opistorkhoza i difillobotrioza v basseine Eniseia.

Current epidemiological situation on opisthorchiasis and bothriocephaliasis and possibility of its alteration due to hydro construction is characterized. Construction of the Bratsk and Krasnoyarsk reservoirs led to development of new large foci of bothriocephaliasis. There is a possibility of developing new foci near other operating reservoirs or near those under construction and design. Foci of bothriocephaliasis on the Yenisei reservoirs are supposed to be more intensive than foci on the Angara reservoirs. Some opisthorchiasis foci are found in the Biryusa basin, local cases of human invasion are registered in regions on the Taseyeva river, down the Angara, and in one of the Yenisei regions where invasion foci of low intensity are supposed to exist. Reservoir construction on the Yenisei and Angara will not promote the development of new opisthorchiasis foci.
