All traffic stations and highway epidemic prevention checkpoints should carefully check the negative certificates of Shanxi health code, travel card and nucleic acid test for entry-exit personnel within 48 hours, and immediately conduct another nucleic acid test for those with life history of epidemic areas and those with abnormal Shanxi health code and travel card, register information and push it to the local prevention and control office to implement corresponding control measures. In principle, the epidemic prevention checkpoint of the expressway will dissuade those who have lived in the epidemic area and have no fixed residence in our city. According to the latest epidemic prevention regulations in Yuncheng, entry and exit from low-risk areas in China can only be released by showing the health code and green code of the travel card, while entry and exit from medium and high-risk areas in China need to be quarantined 14 days on the basis of showing the health code and green code of the travel card and providing negative proof of nucleic acid test.
Health codes are based on actual data and can be generated by citizens or people who have returned to work through online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The promulgation of the Health Law aims to make the resumption of work more accurate, scientific and orderly.
