Clinical Multimodal Surveillance of Respiratory Syndrome Pathogens

Overview

This nationwide, multicenter observational study will establish and improve a hospital-based clinical surveillance and early warning system for respiratory syndrome pathogens. Clinical data and biospecimens generated during routine care will be collected from participating medical institutions every two weeks to monitor pathogen trends, support risk assessment, and provide evidence for prevention and control measures.

This study will enroll eligible patients with respiratory syndrome from fever clinics, emergency departments, outpatient clinics, and inpatient wards in participating hospitals across seven administrative regions in China. Standardized clinical data, including demographic information, symptoms, diagnoses, laboratory tests, medication orders, oxygen therapy, hospitalization, ICU admission, and outcomes, will be reported through encrypted data channels every two weeks. For eligible participants meeting the tiered diagnostic criteria, respiratory samples and clinically remaining biospecimens will be tested using routine pathogen testing, multiplex PCR or targeted sequencing, metagenomic next-generation sequencing, antibody testing, cytokine testing, and exploratory multi-omics assays as clinically appropriate. The study aims to generate national and regional surveillance reports and support early warning, pathogen identification, and prevention and control strategies.
