Your RT PCR test is positive after 1 month of the covid infection and at the same time you are asymptomatic at present according to your statement and not even a single symptom according to your message. My first question is why you repeated the RT PCR test after 1 month. Patients who had infection even after the recovery from the infection also the RT PCR test comes positive sometimes because of the presence of the dead virus in the nose. Try to confirm by doing the covid-19 antibody test and if the antibody test is positive then you are not suffering from any infection.

If you are asymptomatic, no need to repeat the test
