Why do companies need to conduct nucleic acid testing every day?

Nucleic acid is produced every day, because COVID-19 spreads quickly and is concealed. So as to detect the virus infection more closely and prevent the virus from spreading.

First of all, most epidemic infections are caused by Omicron mutants, which spread quickly and have strong concealment. After infection, most patients are mild or asymptomatic, and the virus is easy to spread among people, and the mode of transmission is more subtle. In order to prevent the infection from getting worse, it is necessary to do nucleic acid screening every day and isolate the infected patients in time.

In addition, COVID-19 usually has a certain incubation period after infection, and there will be a window period from the infection of new coronary pneumonia to the detection of the virus, so the virus is not easy to be detected, which may easily lead to missed detection.
