Comrades in charge of the relevant departments of the Ministry of Industry and Information Technology: On the one hand, we have made every effort to ensure production, on the other hand, we also call on all sectors of society to correctly understand the scientific use of N95 masks. Academician Zhong Nanshan, the leader of the high-level expert group of the National Health and Health Commission, also reminded me in an interview with CCTV "News 1 + 1" that in fact, the protection of ordinary people in daily life does not necessarily have to wear N95 masks, general medical Protective masks can block most of the viral droplets from entering the respiratory tract, which is enough in public places. N95 masks are used when facing patients at close range. For example, medical staff are diagnosing and treating patients every day. You have to wear this and change them for a few hours. So you do n’t have to hoard N95 masks because of panic. After all, the current is a difficult period.
