Epidemiology and course of infectious diseases during the covid-19 pandemic. Report 2. Interference engaged between SARS-COV-2 and acute respiratory viral infections

Abstract

The analytical review, based on the analysis of literature and own materials, outlines the features of the interaction of a new coronavirus infection (COVID-19) and acute respiratory diseases. Particular attention is paid to the combined course of SARS-CoV-2 and the influenza virus, a comparative characteristic of the severity of the clinical picture. An assessment of the epidemic situation against the background of the COVID-19 pandemic in foreign countries and the Russian Federation made it possible to establish the presence of the phenomenon of SARS-CoV-2 interference with other viral respiratory agents, based on the facts of a sharp suppression of the circulation of influenza viruses, respiratory syncytial virus (RSV) and other pathogens of acute respiratory viral infections (ARVI) during the period of active spread of pandemic coronavirus. The results obtained confirm the need to ensure effective surveillance and additional diagnostic capabilities for monitoring SARS, which can significantly affect the decision-making on appropriate preventive measures and clinical management of relevant diseases.
