How do eight healthy horses become red horses?

Are you asking what happened when the health code became red team? 1, confirmed case, suspected case, asymptomatic infected person. 2. Close contacts and sub-close contacts with confirmed cases, suspected cases and asymptomatic infected persons. 3. People living in high-risk areas in recent 14 days. 4, all centralized isolation medical observation and home isolation medical observation personnel. All these situations will become red team.

The method of changing the red code to the green code: the health code red code personnel need to complete the centralized isolation medical observation for 14 days, and do nucleic acid detection on the isolated 1, 4, 7 and 14 days respectively. If all the nucleic acid test results are negative, the isolation can be lifted and the health code can be changed to green code. However, if the nucleic acid test results are positive twice, COVID-19 will be diagnosed and then treated. After the treatment is completed, the isolation can be lifted and the health code can be restored to green code.
