Zhejiang health code is not very accurate.

Don't go out. The health code turns yellow. The main consideration is that the confirmed or suspected patient has walked around nearby, which will also lead to the yellowing of the health code. If everything is normal, but the health code is yellow, it may be caused by the false alarm of the health code system. You can contact the relevant personnel for handling. Don't panic if you find that your health code has changed. This is a normal phenomenon for safety during the epidemic. What the yellow code personnel need to do is to contact the community at the first time to verify the information about the epidemic; After the report, you need to conduct self-examination to see if you have a history of contact with officially announced cases, or have a recent history of living in high-risk areas. If the investigation confirms that there is no such situation, you can contact your community in time to apply for transcoding; Or appeal through the "Online Appeal" function at the bottom of the health code display page. If it is fast, it will turn green in about 24 hours.
