Just stay at home, and the prevention and control center should call you again. No, they should also contact your community or village office, and these departments will come to know the situation. Don't panic, getting sick and catching a cold is still allowed. Then tell the truth, don't hide it.
Just do a good job in air defense and epidemic prevention. Wear a mask when going out, wash your hands frequently and do a good job of personal hygiene. Don't go to crowded places. If you don't get a call from the air defense center, they will call you again. It's okay. I missed the call. They should pay a return visit At present, no one is missing in the epidemic, and the staff will be very responsible for implementing the regulations.
Don't worry too much about this. If you catch a cold, you should pay attention to wearing a mask to reduce contact with people. If you can't call the relevant staff, they will call again. Just wait carefully. If you are worried, you'd better go to the hospital for a related examination and make a definite diagnosis.
