I had a postive Covid case 2-3 weeks ago have been out of isolation for 9 days had to go to a and e on Sunday night they asked to do a Covid test I said I’ve just had Covid and the test can stay positive for 30 days even if you won’t be able to spread it or have it nurse agreed but took the test I’m now showing as positive. I’ve only left the flat once in the 9 days too get supplies and then for my daily walk where I don’t meet anyone. Would you still isolate even if you don’t have it
