Nowadays, thousands of citizens who live in Shanghai have been infected by coronavirus disease 2019, a kind of dangerous virus. So what should we do to prevent ourselves from being infected and stay healthy?

   When people are infected by coronavirus, some just have a fever or slight cough, some develop pneumonia, but others can become more serious or even die. If you have these symptoms, please don’t go anywhere and call your local health commission for help.

   Even if you are healthy and not infected by coronavirus, you should still take self-protection seriously. Always wear medical protective masks when you go out and avoid going to places with poor air flow. It’s also necessary to maintain good living habits, such as keeping your bedroom clean, washing your hands carefully and having enough sleep.

   Although coronavirus is frightening, I believe humans can defeat it together and we can come back to study in our school as early as possible.
