Will people who contact the yellow code turn to the yellow code?

It depends. If the other party is a person who has stayed in a key epidemic area for more than 40 minutes and has not been tested for nucleic acid, it may turn into a yellow code if it comes into contact with him. If the other party just passes through the epidemic control area and comes back with negative nucleic acid test, it will not turn into a yellow code when it comes into contact with him.

The health code is a personal health QR code, which is generated by WeChat applet. As the health certificate of the code holder during epidemic prevention and control, it is used to judge the health risk level and dynamic health certification of personnel.

The background is displayed in red, which indicates that the code holder belongs to home quarantine personnel, centralized quarantine personnel, close contacts, suspected patients, confirmed patients, nucleic acid positive personnel or those who arrive in key epidemic areas in Guangzhou, and needs to be subject to epidemic prevention and control management according to relevant regulations. The background is yellow, which reminds people at risk of the epidemic in COVID-19. People don't have to be overly nervous, just go to the nearest temporary sampling point (or medical institution) for nucleic acid testing as soon as possible to reduce unnecessary going out. After the nucleic acid test result is negative, the health code will return to the green code. The background is displayed in blue, which is generated by the code holder's own application, indicating that the health risk status of the code holder is normal. The background is displayed in green, which is generated by someone else's application, indicating that the health risk status of the code holder is normal.
