Will the health code of the dangerous area change color during the travel route? The risk of medium risk area increases in horizontal modulation. Moreover, before the adjustment, some passengers went out to take the same high-speed train, which may be the same car or an adjacent car. This data is calculated through the big data of railway passenger transport, not because they passed through a certain place, but also because close contacts of people in other high-risk areas took the high-speed rail.
Matters needing attention in dangerous areas of high-speed rail lines
At present, the division of medium and high risk areas in China is generally in a relatively small range, and most of them will not be medium and high risk areas in the city. If we only pass through one of the cities in the middle and high risk area, it doesn't mean that we pass through the middle and high risk area. However, people who may pass through high-risk epidemic areas should actively report to relevant staff.
The current epidemic situation in China is still very serious, so if it is not necessary, it is recommended not to travel abroad, especially across provinces and cities. If you must go to other places, avoid going to high-risk areas and cities. You'd better check the middle and high risk areas before going out.
