Researchers are conducting a nationwide, multicenter observational study to establish and improve a hospital-based clinical surveillance and early warning system for respiratory syndrome pathogens. The study will include patients with respiratory syndrome from various hospital settings across seven regions in China. It aims to monitor pathogen trends, support risk assessment, and provide evidence for prevention and control strategies over several years. Participants diagnosed with respiratory syndrome will have clinical data collected every two weeks, including demographics, symptoms, diagnoses, lab tests, medications, oxygen therapy, hospital stays, ICU admissions, and outcomes. For those meeting specific diagnostic criteria, respiratory and other biospecimens will undergo a range of tests including routine pathogen tests, multiplex PCR, targeted and metagenomic sequencing, antibody and cytokine testing, and exploratory multi-omics analyses. During the study, data and specimens will be collected routinely from participants receiving clinical care. Researchers will generate national and regional surveillance reports to support early warnings and prevention efforts. The main outcomes measured include detection rates and types of respiratory pathogens and immune responses after infection or vaccination, tracked over three years. Participation involves regular data reporting through secure channels without additional treatment interventions.
