Possibly 6 though we weren't all able to get tests.
1 of them who tested positive is a friend of a friend, she is still suffering months on.
Second was an older but healthy woman, all the classic symptoms and ill for months.
2 were young children (4/5) (but could likely be any virus as they weren't tested) both had high temp for days which was difficult to bring down, in same class at school - symptoms were about two weeks apart (one of them was mine and the second developed her symptoms just as school shut).
The other two were me and my eldest daughter. I had dry cough (lasted about a month) and breathlessness and fatigue (lasted two weeks) no temp (I'm asthmatic).
Eldest dd (teen) had really high temp and sore throat and tired - again no test, but ill for about a week - she was the first of my household to get ill at the last week of feb ( lI took her to the docs on 27th feb, three days into her illness as we thought she might have tonsillitis and need antibiotics (I know the exact date as some chump ran into the back of my car on way back from docs!).
Of the 3 in my house (DH had no symptoms etc) we were ill over the space of 6 week period and from last week in feb so could easily have been any bug but I do suspect covid, I am still using my inhaler much more than i ever did (during my illness I was taking my inhaler upto 10 times a day, 3 puffs at a time - previously I hadn't needed my blue inhaler for about a year). I now use my inhaler about 3 times a week but no cough or fatigue and all three kids have no lasting effects of whatever bug they had.
