Positive lft middle of Jan, developed a cough but nothing else. Finally tested negative on lft on days 8 and 9. Three weeks without symptoms. Meanwhile covid still circulating in class (primary age) - regular letters about "A case" in your class. Bad cough this morning, did an Lft (yes I know PCR for symptoms but wanted an initial check) - positive!
With the new symptoms and the negative LFTs between positive results, it does seem like it is a new infection. But 4 weeks? So frustrating. Symptoms are mild thankfully but obviously it is now another isolation period.
