LONG covid? COVID Pneumonia?

It seems to me the first variant was the worst especially for taste and smell. For 54 hours I had the worst headache I’ve ever had in my life. I picked it up at my small church. Tonight is the anniversary of when it was passed around at our church at a week before thanksgiving service. I will be going again tonight. We just moved into our present location and only have 30-50 at this time on any Sunday. Last Sunday a gentleman that was there for his first time was coughing his head off and got up and walked out for 10 minutes and came back. After church I was in my car across the street when he walked out. He was coughing so hard I think he puked. As he walked down the street he was spitting out mucus. I couldn’t help but think here we go again but I’m sure I would know by now if I picked up anything. Three days seems to be the magic number.
