How do you know whether to rule it out after receiving a short message from the Shanghai Prevention and Control Office?

Report to the community and cooperate with the epidemic prevention work, and the community will tell you.

Received a short message from the Office of Epidemic Prevention and Control, suggesting that you may have been exposed to positive cases in COVID-19 or high-risk areas. You don't have to be too flustered, report to your community in time, temporarily avoid unnecessary going out, and actively cooperate with the development of nucleic acid testing. If it is confirmed that you have no intersection with positive cases or high-risk areas in COVID-19, and the nucleic acid test is negative, you can resume your daily life.
