COINFECCIONES VIRALES RESPIRATORIAS: UNA REVISIÓN SISTEMÁTICA SOBRE SARS COV-2, VIRUS DE LA INFLUENZA, VIRUS RESPIRATORIO SINCITIAL

Abstract

Introduction: Respiratory diseases are an important cause of morbidity and mortality in the general population, but it affects older adults, children and immunocompromised people to a greater extent, with viruses being responsible for 80% of these infections. Studies have shown that influenza virus and respiratory syncytial virus are the most commonly identified agents. Since 2019 with the beginning of the COVID-19 Pandemic, the world's population has undergone great changes, with thousands of infections, deaths and economic losses. Methods: A systematic electronic search of articles published from 2018 to July 2023 was carried out in the databases PubMed, Springer Scielo, ELSEVIER, Google Scholar. Descriptive, retrospective, prospective, observational, meta-analysis, original articles were chosen, which provided statistical information, for their search keywords such as: COVID 1, co-infection, respiratory co-infection, SARS Cov-2 infection, influenza virus, respiratory syncytial virus. Results: With the literature review, 552 articles were obtained, of which only 73 were chosen according to the eligibility criteria, excluding 52, with a total result of 21 scientific articles. Conclusions: The present systematic review provides evidence on the presence of viral respiratory co-infections in SARS COV-2 positive patients, although the incidence of COVID-19 remains high, the prevalence of respiratory viral co-infections is relatively low. Global infection control measures may have contributed to reducing the circulation of respiratory viruses.
