      As for the part of wearing masks, there was a correct way to wear and remove masks years ago. Those who haven't read it should take out a small book to write down the key points.
For "frequent hand washing", the focus is on the word "frequent hand washing"! How important is it to wash your hands frequently during the virus? Japan's variety show "what's the best?" I did a very hard core experiment, and I was scared
The program is aimed at influenza, but influenza and the new coronavirus are similar in the way of infection, but also droplet infection and contact infection.
Droplet infection is the biggest reason why we wear masks when we go out and don't go to crowded places. In the experiment of the program group, the maximum pollution radius is 3 meters, but generally speaking, in the place with better air circulation, the droplets emitted by the coughing people can rarely infect people after more than 1 meter. But in the crowded and airtight environment, it is possible to be infected at a little distance.
