The State Administration for Market Regulation has approved the construction of a batch of national standard substances for type A influenza virus.

Today, the reporter learned that the State Administration for Market Regulation has approved the establishment of a batch of national standard substances for type A influenza virus, providing precise measurement support for the scientific prevention and control of type A influenza epidemic. Recently, many areas in China have entered the peak season for influenza, and the activity of influenza virus has significantly increased. It is expected to become the main pathogen of acute respiratory infectious diseases in China from this winter to next spring. This batch of type A influenza virus standard substances covers various subtypes currently prevalent, such as H3N2, H1N1, H5N1, and H5N6. The preparation methods include inactivating the virus and pseudo virus, which can be used to analyze the nucleic acid concentration of type A influenza virus in samples, ensuring the effectiveness of virus monitoring data, reducing the risks of false negatives and false positives, providing a scientific basis for epidemic monitoring, virus variant tracking, early warning, and public health decision-making.
