Will the health code in the dangerous area change color when the train passes by?

When passing through high-risk areas by train, the health code will not change color. However, if there are passengers in the car who have been to the middle and high risk area, the health code may change color. So the safest thing to do now is to reduce unnecessary travel, otherwise any mode of transportation may be desperate.

The itinerary card will mark the cities in the middle and high risk areas with *, but this will not affect the itinerary, regardless of the health status, as long as the health code is green. However, it should be noted that if you are a time companion, it may happen that you have never been to an epidemic area, but your health code has changed color. If you see yourself marked as a space-time companion, you need to report to the community and conduct self-health monitoring for 14 days.

Precautions for using health codes:

Using scanning code to verify the flow trajectory of managers. For places or units that need to record the information of people entering and leaving, health codes are encouraged to be used as electronic health certificates for individuals entering and leaving. By scanning and verifying the presented health codes, a traceable track can be formed, and the risk of epidemic spread caused by personnel flow can be reduced.

Strengthen the verification and management of people coming to the spring in key areas. For people entering the spring in key areas, it is necessary to organize the application for health codes, and make full use of the information of nucleic acid detection and serum antibody detection within 7 days after the integration of health codes for verification management.
