As we all know, COVID-19 is mainly spread by droplets, so masks are the most effective measures to prevent virus infection. The school also requires students to wear masks during school. It is best for students to carry a second-class medical mask with them in case of emergency.

Because when you are active on campus, you may be infected once you come into contact with people. Of course, we should pay attention to changing masks regularly and don't let children wear masks in class.

2. Avoid contact with others and public goods.

During school, you must avoid contact with others and public goods. Such as tables and chairs, floors, door handles, faucets, elevator buttons, etc. In class, if a child has an argument or physical conflict with his classmates, then at this time, it is easy for children to come into contact with these public goods.

3. Learn to wash your hands correctly

(1) Before and after meals: Carefully clean your hands with hand sanitizer or soap according to the "seven-step washing method";

(2) Going out and returning: Wash your hands with running water or use alcohol-based hand sanitizer;

(3) Contact with patients: After contact with animals: Wash hands with soap or hand sanitizer before contact with eyes, nose and mouth, or after coughing or sneezing.

(4) When you are not sure whether your hands are clean, avoid pointing with your fingers and press the elevator button to prevent the spread between your fingers.
