I had the virus in March and did not know it. In fact, I was at my doctors office that day and the doc said I had a fever. Doc listened to heart and lungs and said nothing seemed out of the ordinary. I asked for a ZPac because it works well for me when I get my twice annually upper respiratory infection. Got home and had the chills from fever for 48 hours although fever never rose over 101.5. 48 hours later, fever was gone and I resumed my daily workouts that last for an hour. Loss of taste lasted for a week and cough also remained for a week. About a month later, I took an antibody test and tested positive. Knowing that tests can be less than dependable, I went for a second test at a different location and got same result. I later donated plasma at the blood center. Have a friend/neighbor a couple of years younger than me that died from it. Obviously it impacts different people in different ways. According to the experts, I was at extraordinary risk in several ways but managed to escape serious harm. Honestly, it was less harmful to me than the upper respiratory infection that I get a couple times each year.
