[Expert consensus on quality management of multi-pathogen surveillance for acute respiratory infectious diseases].

Since 2024, the National Disease Control and Prevention Administration has implemented sentinel surveillance for acute respiratory infectious (ARI) diseases to monitor the epidemiology and etiology of multiple pathogens such as influenza virus and SARS-CoV-2. To ensure scientific rigor, standardized procedures, accurate and reliable data, and the efficient operation of network laboratories, a multidisciplinary expert panel-including representatives from the disease control and prevention system, sentinel hospitals, schools of public health, and research institutes-jointly developed the Expert Consensus on Quality Management for Sentinel Surveillance of ARI Diseases. The consensus was formulated through multiple rounds of discussion, investigation, and public consultation, incorporating national surveillance protocols, technical guidelines, scientific evidence, and practical experience. Focusing on establishing a comprehensive quality control system for the entire multi-pathogen surveillance process for ARI diseases, the consensus outlines key components covering all stages: target population definition; specimen collection, transport, aliquoting, and storage; laboratory infrastructure and equipment management; multiplex pathogen detection and gene sequencing; quality assurance of test results; biosafety; personnel training and assessment; and data management and analysis. This document aims to provide end-to-end technical guidance for quality control in ARI sentinel surveillance in China.
