RESUMEN
The role of influenza and parainfluenza viruses, respiratory syncytial viruses and adenoviruses in the etiological structure of morbidity in acute respiratory virus infections (ARVI) in children hospitalized during the 19 year period is analyzed. As the result of examination of 56,287 patients by direct immunofluorescent test, respiratory viruses were detected in 21% of cases. The seasonal character, periodicity and level of ARVI morbidity were established. According to medical records, in the 1990s ARVI took a more severe course in children than that observed in the 1980s. In addition, the data on morbidity among children regarding rotavirus infection and ARVI were found to be similar.

To determine the present-day specific clinical features of viral hepatitis A (HA) in children, observation on 447 children aged 1 year and 10 months to 14 years with verified HA monoinfection was carried out. At the season of 1993 essential differences were observed in the clinical picture of HA: the disease took a more severe course with the prevalence of medium-severe (59.3%) and severe (3.6%) forms of this infection, a tendency to a prolonged convalescence period and fermentative aggravations, an increase in the occurrence of cholestatic forms. One of the causes of this phenomenon may be attributed to changes in the properties of the infective agent.

To improve the etiologic diagnosis of acute intestinal infections in children and to identify a rotaviral infection, a solid-phase coagglutination test for the detection of a rotaviral antigen has been introduced into the complex of diagnostic tests. This method is available and simple, highly sensitive and specific. The authors describe the technique of the test and give their recommendations on how to introduce this test into practice at hospitals for infectious diseases.
