If we want to prevent COVID-19, the first thing is to ban going out, because this kind of COVID-19 is very easy to spread, and its transmission channels are very extensive. As long as you can touch the human mucosa and combine with the receptor, you can enter your body, so as long as you try to avoid going out, you won't be infected by the virus, and you should disinfect it every time you go out.
Be sure to wear a mask when you go out and keep a safe social distance from others. This is very important. After all, there is always a life to live and it is impossible to be isolated at home all the time. But you must take protective measures when you go out. You must wear a mask, because it can help you stop the virus in the air. Keeping a safe social distance is to prevent others from carrying the virus and infecting you. As long as you can avoid some physical contact, there is no way for the virus to appear out of thin air and infect you. And don't touch the outside of the mask with your hands after wearing it, because the outside of the mask has been in contact with the air. If your hands touch it, you may be infected with a virus with germs.
Secondly, we must do more exercise. After all, it is best to have a strong body no matter what disease you face. For example, a player just infected COVID-19, isolated himself at home, and continued to exercise. I recovered the next day. This is because players often exercise in the body shop, so they are stronger. In the face of virus invasion, its own defense system can kill the virus in time and then let itself recover.
