I bet there are Millions if not BILLIONS who have had it and never knew it. I tested positive two weeks ago today. I am STILL positive but past the contageous point. Through it all, I never once had any symptoms that made alarmed. The night after I tested positive, I felt REALLY tired but the night before I had maybe 4 hours of sleep and then went on a very long walk the next morning. The big thing is "CHECK YOUR TEMPERATURE!" My Wife, who even lost her taste and smell (It's still gone a week after testing Negative again) and I both never once had a temp that was even close to high. I have had allergy attacks that were FAR worse. I KNOW we were the lucky ones and both have said that we were blessed to not be in a Hospital or dead. It makes me stand by what I said months ago....You REALLY cannot stress over it. Even with the vaccine and now variants of Covid out there, it's gonna be a LONG time before concrete findings come along.
