Is it positive to receive the short message from Taizhou CDC now? No nucleic acid positive report?

Now I have received a short message from Taizhou CDC, which is positive and has a nucleic acid positive report. According to the relevant public information, this is to remind him that there may be a risk of infection. He must do personal protection and go to the nearest nucleic acid testing institution for testing immediately, that is, your nucleic acid test may be positive and needs to be rechecked.
