How long will it take for Shanghai to turn yellow after receiving text messages?

Generally, the nucleic acid will turn yellow within 48 hours if it is not reported according to the SMS requirements.

At this time, it is necessary to report to the community, neighborhood Committee, unit or hotel where you live in time. Then immediately carry out nucleic acid detection, which needs to be completed twice within 72 hours, with an interval of 24 hours. We need to be isolated at home until the results come out. If the results are all negative, notify the community of their own sexual report, submit the nucleic acid test report online, and then apply for "transcoding" to return to normal.
