Wearing a mask is an important measure to prevent the spread of novel coronary pneumonia. New coronary pneumonia is highly contagious, and its transmission is mainly through person-to-person droplet transmission and contact transmission. Wearing a medical protective mask can effectively reduce the possibility of droplet transmission.
In addition, while wearing a mask, we also need to take preventive measures such as reducing parties, reducing unnecessary travel, and washing hands regularly to reduce personal exposure and the chance of infection. However, masks should be selected with protective functions, such as medical surgical masks, N95 masks, etc.
