[Possible influences of climatic changes on the spread and intensity of foci of some human helminthiases].

Climatic changes on the Earth and in some of its regions have caused and will cause alterations in the natural and social factors which may influence the circulation of causative agents of helminthiases that develop both on land and in water with the participation of hydrobiont. These include changes in the size of the first and second intermediate hosts, in the hydrological conditions of water reservoirs, in the amount of precipitation, soil moisture, heat, etc. Therefore, the expected global warming may alter the areas of some helminths, the intensity of foci, etc.
