Résumé
Norovirus, as one of the main pathogens causing non-bacterial gastroenteritis, can cause serious public health problems and economic losses around the world. In recent years, the outbreaks caused by the virus in China are on the rise. Human Norovirus (HuNoV) can hardly be cultivated in-vitro. The nucleic acid detection method (such as RT-qPCR) has the highest sensitivity and specificity, but it was not established that the correlation between the detected viral genome and viral infectivity, which leads to inaccurate judgment of safety risks. Here, the in-vitro and in-vivo culture models, viral genome integrity and capsid protein integrity were cut into three aspects. The research progress and characteristics of infectious Norovirus identification technology in recent years were reviewed and discussed, and the future development trend of this technology was prospected. The aim is to further improve the accuracy of Norovirus quantitative detection and provide a theoretical basis for its application in the field of food safety testing.
