No it's been too long since I've had it. Medical people say you'll show positive up to 90 days after having covid.
Antibodies no one knows yet for sure how long they last.
Talking antibodies I had a very bad case of the Hong Kong flu back in the late 60's 12 years old.
I was very sick for two weeks.
I've never had the flu or really sick since until I had my covid case December 2020.
