The paper considers topical problems in the scientific and methodological provision of epidemiological surveillance of rotavirus infection, such as the significance of different routes of pathogen transmission, a trend in the development of an epidemic process, and mechanisms of its self-regulation. The virological and epidemiological data suggest that the role of rotavirus transmission via water is insignificant (contact transmission is typified by the age-related structure of morbidity; water basins and drinking water show noninfectious viral markers, the resistance of which is much higher than that of the pathogen). A total of 8556patients aged 0 to 14 years with acute enteric infections, who were treated at the Children ’s Infectious Diseases Unit, City Hospital One, Rostov-on-Don, were examined for rotavirus in the period from February 2006 to January 2009. Group A rotaviruses were detected in 34% of the patients. Examination of variations in the trend of rotavirus incidence in children of different ages revealed a set of epidemiological parameters reflecting the dynamics of an epidemic process -phasic development and a change in epidemic infection cycles in the urban population. There was a continuous alternation of epidemic cycles every 2-2.5 months. The developed methods for monitoring the epidemic process make it possible to accurately assess the current epidemiological situation and to predict higher morbidity among infants.
