From "red code" to "yellow code": the confirmed case was cured and discharged, and there was no recurrence symptom in isolation period 14 days; The suspected and febrile patients were diagnosed, and COVID-19 cases were excluded. After 14 days of quarantine, COVID-19's symptoms did not appear, and a "yellow code" was issued.
Change "yellow code" to "green code": Close contacts have no COVID-19 symptoms after flow adjustment, and the "yellow code" is changed to "green code" after isolation 14 days.
The causes and solutions of the health code turning red are as follows:
1. Close contacts need centralized isolation 14 days, and home isolation for 7 days, totaling 2 1 day. After six nucleic acid tests, if all the results are negative, red team can be published.
2. If it is a sub-close contact, it needs to be isolated for 7 days, and the nucleic acid test should be done three times. If the nucleic acid test results are all negative, the green code can be restored.
3. If it is a person in a closed control area or a person in a high-risk area, after the closure is lifted or the high-risk area is reduced to a low-risk area, the red health code will be released accordingly.
4. If you don't know the reason of red team, you can click View Reason next to red team after opening the health code to find out the corresponding situation and follow the prompts.
