Health code color conversion
When people with green codes enter the low-risk area without special circumstances, the health code will not change color, that is, it will be normal green. If the person with the green code enters the middle and high risk area and stays long enough, and the mobile phone can receive the communication roaming information normally, the health code will automatically change color from the original green code to the yellow code or the red code.
When people with code yellow or red team enter the low-risk area, they can automatically record the time of arrival in the low-risk area as long as they turn on their mobile phones. After quarantine 14 days, if the code holder does not become a secret contact or COVID-19 case, the health code will automatically change back to normal green health code.
If the health code holder becomes a secret contact or a confirmed case, and the information is reported to the coding company platform by the code holder himself, the coding platform will turn the green code of the code holder into red.
If the code holder is diagnosed as a case or a suspected case, the coding platform will change the red health code of the code holder into a green health code 28 days after the date of rehabilitation and discharge. For close contacts, if they do not become COVID-19 cases after 28 days from the date of contact, the red health code will be changed from the coding company platform to the green health code.
