Analysis of Single Respiratory Viral Infections Versus Co-infections: Prevalence and ICU Needs in Hospitalized Adults

This study aims to determine the prevalence of viral respiratory agents in hospitalized patients post-COVID-19 and to examine the clinical course of respiratory viral co-infections, which are expected to be more severe. This study will be conducted retrospectively at Kocaeli University Hospital between May 2023, considered the end date of the pandemic, and January 2024. Patients over 18 years of age will be included, and data will be accessed through the hospital automation system. Patients with SARS-CoV-2 PCR-positive symptoms and those expected to use molnupiravir due to the need for treatment will be considered as COVID-19. Respiratory tract agents will be detected by multiplex PCR from symptomatic inpatients. All patients with influenza will also receive oseltamivir. The distribution of viruses, the need for intensive care hospitalization, and whether they cause death within seven days, as well as the prevalence, clinical course, and risk factors of viral co-infections expected to be clinically more severe in the literature, will also be examined
