What should I do if the health code nucleic acid test is negative and the hospital informs positive?

First of all, it may be because there is an error in the nucleic acid test report of the hospital, or it may be a work error and the wrong person was notified. If this happens, we should do the nucleic acid again. After all, we'd rather believe it exists than it doesn't. In this extraordinary period. We should always be vigilant. Safety is the most important thing.
