I got COVID in January after the Daytona 24 Hour race. My crew and I get tested every week because we travel so much. I had a positive PCR test and never had a sniffle. No fever, no headache, no nothing. I figured it was a false positive so I waited my 10 days and retested, positive again. After 2 weeks went and got an antibody test and it too was positive. So, I had it, and never knew it. It leveled 3 of my crew guys and one went to the hospital. 2 of us were totally asymptomatic.
My wife never isolated and slept in the same bed as me the entire time (she figured if I had she had it). She tested 4 times, all negative.
It’s hit or miss, my Aunt died from it 3 days before I was diagnosed.
