I will ask again...
HOW LONG AFTER testing positive did you receive a negative RT PCR test or PCR test? CDC advised that. Virus can live in your nose up to 90 days.
Although the OP mentioned a PCR test with regard to his original infection, he also referenced travel to the USA, and the antigen test required to travel there. That why some, including me, have responded with anecdotal experience involving antigen tests.
