What is the purpose of calling back to Shangqiu epidemic prevention station?

Ask about the places you have been recently. It is normal to call back to Shangqiu epidemic prevention station. During the epidemic, many people received calls from the epidemic prevention and control center in order to check the close contacts. I'm just calling to ask where you've been recently and whether you've had close contact with the confirmed cases. 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.
