On October 20th, 20021,1,1,the faculty member had close contact with a confirmed case in Suzhou, so on the 25th, the faculty member was diagnosed as asymptomatic infected. Because of him, all the teachers and students in this school do nucleic acid tests overnight. Therefore, Bian Xiao suggested that during the epidemic period, never go out or contact patients with cough or fever at will. Because many patients are basically asymptomatic now, you can't see his physical condition, so you are easily infected if you are not careful.

How to prevent the epidemic? 1, try to reduce your outdoor activities and try not to go to some crowded public places, such as cinemas, Internet cafes and supermarkets. Because in these public places, you don't know what everyone's physical condition is. Now many COVID-19 patients are basically asymptomatic. So from the appearance, you can't tell whether the other person is infected with the virus. Even if you want to enter these public places, you must wear masks, and it is best to choose medical masks.

2. Pay attention to personal hygiene at ordinary times. For example, when you go to the toilet or come home from a public place, you must wash your hands with hand sanitizer or tap water for not less than three minutes, because only in this way can the bacteria on your hands be washed away. If you are out for a long time, you must take off your clothes in time to disinfect when you go home.

3, you can prepare a thermometer at home, and then check your body temperature for yourself and your family every day. If you have a fever or cough, you must go to the hospital in time and wear a mask on the way to the hospital.

4, you can usually do more exercise to enhance your body's resistance. Because most people infected with COVID-19 are people with weak resistance. It is recommended to exercise for about 30 minutes every day, because if you exercise for too long every day, you will easily get hurt.
