For people in high-risk areas, the color of their health code is generally yellow, which will limit their travel, so it is suggested that it is best to carry out home isolation monitoring.
If it is a confirmed case, a suspected case, an asymptomatic infected person, or a person who has close or sub-close contact with it, the health code may turn red. At this time, it is necessary to conduct centralized isolation monitoring according to the requirements of prevention and control personnel.
