[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.

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.

[Current state of epidemiologic surveillance of natural foci of plague of North Caucasus].

Information on the epizootic situation in plague in the natural foci of North Caucasus and on the influence of a number of anthropogenic and natural factors on this situation is presented.
