RSV in Acute Respiratory Infection Surveillance Among Community-Dwelling Elderly Aged ≥50 Years in China

This is a multicenter, prospective, observational, community-based study designed to evaluate the incidence of respiratory syncytial virus (RSV) infection among community-dwelling elderly individuals in China, as well as their cohabiting older adults and children, over a 24-month period. During the study, home visits will be conducted to collect nasopharyngeal (NP) swabs from all community residents aged ≥50 years who report symptoms of acute respiratory infection (ARI). Pathogen detection will be performed using both point-of-care testing (POCT) and centralized laboratory analysis.
