Abstract

Objective. To identify the specific features of the development of the epidemic process of acute respiratory viral infection (ATVI) in relation to the pathogen etiology attribution. Materials and methods. The weekly results of PCR diagnosis of the causative agents of influenza and ARVI were analyzed using the database of the A. A. Smorodintsev Research Institute of Influenza, Ministry of Health of Russia, in 4 cities (Yekaterinburg, Kazan, Rostov-on-Don, and Saint Petersburg), as well as data from the Virology Laboratory, Center for Hygiene and Epidemiology in the City of Moscow. Results. In 2014-2018, the largest proportion of the causative agents of influenza and ARVI were parainfluenza virus types 1, 2, and 3 (25.5%), influenza A (H1N1) 2009 (25.2%), and influenza A (H3N2) (24.3%) viruses in Moscow, rhinoviruses (24.6%) and influenza A (H1N1) 2009 (21.2%) virus in Yekaterinburg, rhinoviruses (26%) in Kazan, rhinoviruses (19.6%) and adenoviruses (18.2%) in Rostov-on-Don, and influenza B (20%) and influenza A (H3N2) (19.3%) viruses in Saint Petersburg. By and large, the epidemic process of influenza and ARVI in the 5 cities began with parainfluenza infection and ended with influenza infection caused by the influenza B virus. Unlike influenza viruses, non-influenza etiological agents were characterized by longer activities. Conclusion. The manifestations of the epidemic process of influenza and ARVI are largely determined by the specificity of causative agents and have developmental features in both different territories and different population groups.
