What does it mean to send text messages after receiving epidemic prevention and control?

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.

"2+ 14": check the negative proof of nucleic acid test within 2 days (48 hours) and conduct daily health monitoring 14 days.

"14+7": that is, 14 days of centralized isolation +7 days of home health observation.

Health management measures for nucleic acid positive patients after sub-closed inoculation;

If the nucleic acid detection results of close contacts were negative at 1 and 3 days, and those of sub-close contacts were negative at 1, 3 and 7 days, the sub-close contacts were released from centralized isolation medical observation on the 7th day.

If the close contact's nucleic acid test results are 1 and 3 days positive, the second close contact will be transferred to close contact management. Close contacts took 14 days of centralized isolation medical observation and 7 days of home health observation.
