I received a text message from the CDC, but the nucleic acid results were normal.

Don't be too flustered when you receive the text message from CDC. The nucleic acid results are normal. According to the public information of relevant information, you received a short message from the epidemic prevention and control office, suggesting that you may have been exposed to positive cases in COVID-19 or passed through high-risk areas. You don't have to be too flustered, report to your village in time, temporarily avoid unnecessary going out, and actively cooperate with the development of nucleic acid testing.
