There are tens of thousands of anti-epidemic measures, and the first is to wear a mask. Wearing a mask is extremely important to reduce the infection of the new coronavirus.

According to research, if the infected person does not wear a mask and the healthy contacts wear a mask, the infection rate is 70%; if the infected person wears a mask and the healthy contact does not wear a mask, the infection rate is 5%; If everyone wears a mask, the infection rate is 1.5%. Wearing masks correctly can effectively reduce the risk of new coronavirus infection.

How to wear a mask correctly:

Masks should be washed before wearing and after taking them off;

When wearing a mask, pay attention to the front and back and up and down. The mask should cover the mouth and nose, and adjust the nose clip to fit the face;

Avoid touching the inside and outside of the mask with your hands during wearing, and take off the mask by removing the strings at both ends;

Wearing multiple masks cannot effectively increase the protective effect, but instead increases the breathing resistance and may damage the tightness;

There is no evidence to prove the effectiveness of various measures such as cleaning and disinfection of masks;

Disposable medical masks and medical surgical masks are for limited use, and the cumulative use does not exceed 8 hours. Occupational exposure personnel should use masks for no more than 4 hours and cannot be reused.
