Approximately three weeks ago my 5 year old daughter had a cold and a bit of cough. She had a temperature at around 100.5f on the first day and no fever after that. My wife and I too started having cough and cold. I had fatigue but no obvious fever as such. During the same time my 70 year old father in law started having same problem but he had bouts of fever which lasted for 2-3 days. After taking Azee for 5 days all of us were fine. My daughter did good without antibiotics. I was infected with covid during the first wave. My wife and father in law have received first dose of vaccination. I keep wondering if it was covid. Can I confirm this without doing any tests?
