Is it normal for the epidemic public security bureau to call people and say that it is screening?

This is normal, in order to check the secret contacts during the epidemic.

Many people have received calls from the epidemic prevention and control center. As long as you have been to high-risk areas and then returned to your place of residence or other places, big data will be fed back to the government, but only the places and telephone numbers you have been to, and then the Social Affairs Department will send someone to call to ask about your situation. Under normal circumstances, you will only be asked to provide information such as your ID number and specific place of residence when you control or call the staff's jurisdiction. In fact, if you don't trust yourself, you should report it to the community. You have to do nucleic acid, and you have to isolate it at home.
