Title: Clinical evaluation and prognosis of respiratory viruses in adult patients admitted to a reference university hospital between 2013-2020.

Abstract: Viral infections of the lower respiratory tract are an important cause of mortality worldwide and led to serious pandemic outbreaks seen centuries before the current COVID-19. Thus, the objectives of the current study were: to evaluate clinical and epidemiologically severe viral infections in the adult population from 2013 to 2020; assess risk factors associated with patients' prognosis; and measure the epidemiological impact of the COVID-19 pandemic in a reference hospital-university service in the region. Based on these purposes, an observational retrospective study, cohort type, was developed about the medical records of patients admitted to the Hospital Puc-Campinas between January 2013 and June 2020 with diagnostic criteria for Severe Acute Respiratory Syndrome (SARS). In this study, we observed the numerical impact and the severity of the COVID-19 pandemic compared to respiratory viruses in previous years, caused by other viral agents such as Influenza and Respiratory Syncytial Virus (RSV). It was also highlighted the expressiveness of the factors of risk/comorbidities in the face of the COVID-19 pandemic, which determined not only greater probability of infection, as well as the patient's prognosis. In this way, the study of patients from a public referral hospital was able to show clinical features and prognosis associated with several acute viral respiratory infections.
