I received a message from 14+7 for no reason.

Recently, the Ministry of Industry and Information Technology released data personnel accompanying time and space. If you receive a SMS reminder from the Epidemic Prevention and Control Office, or find that your health code is abnormal, you don't need to be too flustered. You should report to your community (village) in time, and compare the action trajectories of relevant positive infected people under the guidance of the community to see whether the positive infected people have had contact with themselves and whether they are at risk of being involved in the epidemic. Health management measures of "14+7" shall be implemented for those with contact history or epidemic risk; If it is clear that there is no contact history and no epidemic risk, the individual shall implement the "14+7" health management measures after signing the letter of commitment.
