Why the health code turns yellow:
If you have been active and stayed near the key places where confirmed cases and asymptomatic infected people have stayed, and you may have had contact with confirmed cases and asymptomatic infected people, your health code is listed in the yellow code.
How to clear the yellow code:
What if you have completed the "three-day two-check" after the dangerous period of possible contact with confirmed cases and asymptomatic infected people? 2? Subnucleic acid detection, 2? The time interval of secondary detection is greater than? 72? Hours, and the results are all negative, the system cancels the yellow code and turns to the green code.
