As for the virus is very infectious, according to our experience (the action in China), we strongly recommend:
1. It is better not to go where there are many people;
2. Put on the mask if go to outside, in this way it cuts the droplets from the infected people;
3. Wash hands frequently if go to the public;
4. Have food at home.
It takes unconvenience in this case. But it is very important to reduce the risk.
