[Hydrological dangerous natural phenomena as cause of aggravation of an epidemiological situation]

Materials dealing with the specific features of the territory of Southern Russia, appearing as a consequence of natural, technogenic and some other factors, are presented. These materials indicate that, due to the high flood in summer of 2002, a real danger of a sharp aggravation of the epidemiological situation in acute enteric infections, as well as other infections, arose on a vast territory. As the result of the timely evaluation and analysis of changes in the factors of the natural and social environment, occurring as the consequence of the high flood, prophylactic measures were urgently carried out, thus making it possible to prevent the aggravation of the epidemiological situation.
