Lex - 12 people I know died of Covid in the last 2 years. 3 from my immediate family. Nearly whole my family got a virus - in Poland, U.K. and USA. <br>My question is - we can say when person is getting Covid. How we can say when the person DOESN’T have it anymore? If for 3 months after getting Covid the testing is useless, as it can always come back positive?
