My brother had Covid a month ago and was pretty sick for a few days (O2% of 87 the first night and difficulty breathing). He feels fully cured now but is still testing positive. His doctor told him he might continue to test positive for up to two months, but to ignore it. WTH?! Something’s very wrong here!
Is he testing with snot or spit?
Spit clears faster, usually within a day or two.
Snot can have traces for weeks.
