Didn't Caoqiao, Pinghu, Zhejiang, receive a notice from the community to do nucleic acid?

Nucleic acid detection is the "gold standard" to judge COVID-19 infection at present. The mutant of Omicron is highly contagious, fast and concealed, which further increases the difficulty of epidemic prevention and control.

In the case of community transmission, we should race against the virus. First, we should conduct a large-scale comprehensive screening in the crowd, find out every infected person, especially asymptomatic infected person, through the whole process of testing, and conduct isolation treatment to prevent the virus from spreading.
