You can use alcohol-based disinfection products to clean your hands. Covid-19 is not resistant to acids and alkalis, and is sensitive to organic solvents and disinfectants. 75% alcohol inactivates the virus, so a certain concentration of alcohol-containing disinfection products can be used as an alternative to washing hands with soap and running water.

Part 2. Face masks

1. How to choose a mask?

Option 1: Disposable medical masks, replace them for 4 hours continuously, and replace them immediately after pollution or humidity;
Option 2: N95 medical protective mask, worn for 4 hours, and replaced immediately after contamination or moisture.
Cotton masks and sponge masks are not recommended.

2.Use masks properly

How to use medical masks:

(1) The mask is dark in color on the front side, and the front side should be outward, and there is a metal clip on the nosepiece on the medical mask.
(2) The face facing the face should be the opposite side of the medical mask, that is, the side with a lighter color. In addition, pay attention to the part with the metal strip above the mask, and don't wear it upside down.
(3) After distinguishing the front, back, upper, and lower ends of the mask, wash your hands first to determine whether the mask is correct, and then hang the rope on the ears at both ends.
(4) The last step is also the metal strip problem mentioned earlier. After wearing the mask, you need to press the metal strips on both sides of the bridge of the nose with both hands to make the upper end of the mask close to the bridge of the nose, and then stretch the mask downward to make the mask. There are no wrinkles, and it is best to cover the nose and mouth.

(2) The elderly and patients with chronic diseases of the heart and lung may cause discomfort after wearing, and even worsen the original condition. Professional guidance from a doctor should be sought.
(3) The child is in the stage of growth and development, and his face is small, so choose a child-proof mask.
