Zhang Wenhong, the leader of the Shanghai New Crown Pneumonia Clinical Treatment Expert Group and the director of the Department of Infectious Diseases, Huashan Hospital affiliated to Fudan University: It turns out that in our society, when everyone is infected, those people have symptoms, and you don't know he has symptoms. Therefore, there is no difference in the precautionary measures taken by healthy people to prevent symptomatic and asymptomatic infections. So whenever we are, we still have to be vigilant. Before the global epidemic is completely over, we must maintain good hygiene habits, wear masks, wash hands frequently, and maintain social distance when necessary. I think these methods should be upheld by everyone for a long time. (Source: Look at News Editor Wu Rui)
