Summary
This study will look at 5,900 hospitalized adults aged 60 and older to find out which viruses cause severe lung infections. Researchers will test respiratory samples to track common and emerging viruses like flu, RSV, and COVID-19. The goal is to better understand how often these infections occur and how they affect older people.
