Don't be afraid after it turns into a yellow code. Be sure to contact the local epidemic prevention and control department in time and the other party will tell you how to deal with it.
In principle, the yellow code personnel should be isolated and centralized management, and the green color can only be restored after three negative nucleic acid tests.
If you have been to high-risk places such as Xinfadi recently or have had close contact with relevant personnel, these personnel will be included in community management after verification, that is, the health code will turn into a red code. But don't stay in the epidemic area for more than two hours, maybe it won't become red team.
