Travel codes and health codes are usually prompted by SMS.

This means that you may have had direct or indirect contact with infected people in COVID-19 recently, which needs further verification.

Taking Nanjing as an example, Chen Xuemei, deputy director of Nanjing Civil Affairs Bureau, said that citizens who received the text message should not be nervous. This only means that you may have had direct or indirect contact with infected people in COVID-19 in the near future and need further verification. Also pay attention. After receiving the SMS prompt, if the health code still shows the green code, please don't go out, report to your community immediately, and actively cooperate with the community to check the itinerary.

After verification, those who have been tracked and crossed with the confirmed cases, have a history of living in a medium-high risk area or have been identified as close contacts or sub-close contacts will be arranged for centralized isolation medical observation by their respective districts. People outside the above categories should receive self-health monitoring for 3 days. During this period, under the premise of personal protection and not taking public transportation, we will go to the nearest nucleic acid sampling point for two nucleic acid tests. The interval between 1 and the second nucleic acid detection is more than 24 hours.
