Now the better preventive measures, is to go out less, less gatherings, if you really want to go out, you need to wear a good mask. Masks can reduce contact with droplets and reduce infection. Masks are not randomly selected, but also need to be noted, whether in wearing, or in the treatment of masks, should not be careless. If not handled correctly, it can lead to hidden dangers.

For the new virus infection, we need to know that there are several ways of transmission, mainly contact, droplet, contact is a few close contact, do not close contact. Droplet is oral endocrine saliva, will be produced when sneezing, coughing and talking, wearing a mask can reduce contact with droplet, can not let the virus into the body. According to Zhong, the masks will include N95 and KN95, as well as ordinary surgical masks.

In general, it is recommended that ordinary people use medical surgical masks. People who have been infected or suspected and medical staff need to wear N95 and KN95 masks, which will have a better effect and can greatly reduce the infection by the virus. Once you have chosen a mask, you should also know the correct way to wear it. To do this, turn the dark side out and the light side in, and don't make the wrong choice. Another thing to note is that the mask will have a metal strip attached to the bridge of the nose. After wearing the mask, press on both sides of the bridge with your fingers to ensure that the mask is close to your mouth and nose.

Masks should be thrown away once they come into contact with infected people. If you have not come into contact with an infected person, you should immediately throw away your mask if it is wet or has secretions. Masks should not be reused more than five times or shared with others. For repeated use of 5 times, mainly the general population, people with special circumstances, it is not recommended to repeat use. Wear a mask for no more than four hours, and replace it immediately after that.
