Im 99% certain I had the rona in August. I cannot prove it. I am always healthy, always. I got a funk last august that working in the hots southern sun, I nearly fell out. I could not catch my breath, had an unproductive cough and took about 3 weeks before I was good again.
The people i were around, all got the same shit. Everyone in my house got it, we all thought we caught a funk from mold.
