General health codes are divided into three colors: red, yellow and green. Code yellow and red team are impassable, and medical treatment or observation is required according to regulations. Only the green code can pass when the body temperature is normal. Moreover, the yellow code means that there is a risk of infection and it may be transmitted to others. Therefore, after the health code turns yellow, it will be restricted from traveling, and it will become a green code after nucleic acid detection, and it will be possible to resume normal traffic after the health code turns green. It is recommended to reduce unnecessary travel during the yellow code period.
It should be noted that all personnel from overseas and domestic high-risk areas who have not completed the medical observation period (including centralized isolation and home isolation, etc. ) are not allowed to go to the yellow code personnel dedicated core.
