Etiology of respiratory virus infections among 1699 hospitalized patients (HP) was determined by PCR during the period of increased influenza activity in 2012 - 2013 season. The rate of accidence of influenza virus in dependence of gender, age, social and demographic factors and previous vaccination was analysed. Young children dominated in the age structure of HP, while the elderly were hospitalized very rarely. According to results obtained rate of influenza detection in HP was significantly higher among adults in comparison with children (63,5 and 30,7% of investigated patients, correspondingly). Respiratory syncytial virus and rhinoviruses were detected the most regularly (8.7 and 3.1%, correspondingly) in children, parainfluenza and adenoviruses were registered rarely (1.4 and 2.1%, correspondingly). Rate of detection of coronaviruses and bocavirus was low and varied in the range 0.3 - 0.6%. Indicated above ARI agents among hospitalized adults were detected rarely (0 - 1.5%) with exception of RSV which was detected among elderly (75 - 84 years) in 5.9% cases. No metapneumovirus cases were detected among HP in indicated period. Although males dominated (58%) among HP influenza cases, regardless of the type/subtype, were registered more frequently among girls in comparison with the boys of the same age groups. Influenza cases were registered more frequenly as well among smoking than in not smoking patients. Young children dominated in the age structure of HP, while the elderly were hospitalized very rarely.
