After the meeting, Zhong Nanshan was interviewed on issues of concern to the public.
Regarding the recent increase in the number of patients with respiratory diseases, Zhong Nanshan believes that there are two main reasons why respiratory diseases have entered the high incidence period, one is the conventional reason, that is, after the weather is dry and cold, the immune function of the nasal mucosa is reduced, so the virus is easy to enter the respiratory tract. The second reason is that wearing a mask for a long time will also make the autoimmune system unable to function normally, weakening the ability to resist diseases.
Unless there is a time of a pandemic, or when you go to a place where people gather, long-term wearing of a mask is not particularly recommended. Zhong Nanshan said.
