Wearing a mask is an effective means of blocking the spread of respiratory secretions. At present, the masks that can be seen on the market mainly include medical protective masks (such as N95 masks), medical surgical masks, and ordinary disposable medical masks. In addition, there are cotton masks, sponge masks, etc. often worn by various stars in the market.
Citizens choose medical surgical masks for daily protection. N95 masks have better anti-illness effects, but have poor breathability and large breathing resistance, and are not suitable for long-term wearing.

6. How to use masks reasonably
Disposable medical masks: recommended for the public to wear in non-intensive public places;
Medical surgical masks: It is recommended to be worn by passengers of the Department of Public Transport, sanitation workers, taxi drivers, and service personnel in public places;

When wearing a mask, fully unfold the folded surface, completely cover the mouth, nose, and jaw, and then compress the nose clip to make the mask fit the face completely.
Wash your hands before wearing a mask, or avoid touching the inside of the mask during wearing the mask to reduce the possibility of the mask being contaminated. The inside and outside of the mask must be clearly distinguished. The light color is the inside. The inside should be attached to the mouth and nose, and the dark side should be outward.
Masks should be changed regularly, not on the inside or outside, not on both sides.

Mask expiration is not recommended in principle. For medical surgical masks are disinfected and sterile, bacteria may grow if expired. Now the situation is special.

If this is not the case, it can be used as a backup.

9. Can I wear a mask without a dense crowd?
Go to a crowded place, because there are many people and there is no ventilation, there may be pathogens around you, then wearing a mask is necessary. However, in a densely populated area, if the environment is open, the pathogens are diluted and not enough to infect people, and they may not wear masks. However, if you have symptoms such as cough or fever, you need to wear a mask to prevent infection.

10. Is there a shortage of masks?
Medical surgical masks cannot be reused. The same is true of the N95 protective mask in principle.
But the actual situation is special. For ordinary people, masks are now scarce. If there is no fever or catarrhal symptoms (runny nose, sneezing, nasal congestion, etc.), it can be reused, and the repetition cannot be more than 5 times.
But we have to emphasize that reuse is dangerous.

Washing hands with soap and flowing water for more than 20 seconds can effectively kill pathogens and protect them.
