How to protect yourself from novel coronavirus infection?

(1) Wash your hands frequently. Wash your hands with soap or hand sanitizer and tap water, and wipe your hands with disposable paper towels or clean towels. Wash your hands immediately after contact with respiratory secretions (such as sneezing).

(2) Maintain good respiratory hygiene habits. When coughing or sneezing, cover your mouth and nose with paper towels and towels. Wash your hands after coughing or sneezing, and avoid touching your eyes, nose or mouth.

How to use medical masks correctly;

1. Wash your hands before and after wearing a mask. You should wear the mask according to the packaging instructions, including the tether that firmly fixes the mask, so that the mask is close to your face. If the mask is worn too loosely and does not fit the face, air will enter from the side gap, and the preventive effect cannot be achieved.

2, be sure to cover your mouth and nose, some people just cover your mouth is not correct, because the nose is the main way of human air in and out.

3, masks can not be worn on both sides in turn, because the outward side is easy to absorb germs. If you don't clean it, put the outward side in, which is easy to get infected with germs.
