If the personal health code turns yellow, report to the community first, evaluate the isolation situation at home or hotel according to the community, and continuously detect nucleic acid for three times within 7 days, with an interval of not less than 24 hours. If the test is negative for three times, you can apply to the streets in your jurisdiction to change the yellow code to the green code, and then you can resume your normal work and life.
During the epidemic, you need to show your green health code. When your health code inexplicably turns into a yellow code or a red code, you can't travel.
