Is COVID-19 Fuyang infected again?
It's possible.
COVID-19 relapse refers to that the nucleic acid test turns from negative to positive again after the patients diagnosed in COVID-19 are discharged from hospital, but relapse does not mean that the patients are infected again. Whether it is reinfected or not needs to be judged according to COVID-19's nucleic acid gene sequencing. If the nucleic acid gene sequences that were all negative before are the same, it means that it is not a secondary infection. However, if the viral gene sequencing of the patients infected twice is different and no antibody can be detected in the body, it can be considered that the nucleic acid is positive due to the secondary infection after rehabilitation, rather than recurrence.
In addition, the recurrence of COVID-19 may also be due to the false negative results of two nucleic acid tests before discharge or the false positive results of nucleic acid tests after discharge. At this time, the occurrence of false positive or false negative can be reduced by sampling the limbs many times.
Can people who have regained their crowns still be infected?
It depends.
COVID-19's recurrence means that COVID-19 was found to be positive again after discharge, while COVID-19's recurrence may be due to COVID-19's incomplete recovery due to the patient's poor immunity and weak resistance, or secondary infection after discharge, which led to the recurrence of nucleic acid.
