Abstract

Since the outbreak of COVID-19, SARS-CoV-2 surveillance in sewage based on sewage epidemiology has been established in many countries around the world, while there is a lack of a standard detection method for SARS-CoV-2 in sewage in China. This standard provides three methods for the enrichment of SARS-CoV-2 in sewage, namely polyethylene glycol precipitation, aluminum salt coagulation precipitation and centrifugal ultrafiltration, which are suitable for the enrichment and nucleic acid detection of SARS-CoV-2 in domestic sewage and sewage from medical institutions. This standard is of great significance for standardizing the SARS-CoV-2 detection in sewage and ensuring the scientific and effective detection of SARS-CoV-2 in sewage.
