Glad to hear you are better and Mary is doing well. Prayers do work! 
I did have Covid prior to Christmas. Luckily my symptoms were pretty minor.  Got out of quarantine Christmas Day and went to th in-laws house. My sister-in-law was avoiding me like I had the plague, but I told her I was clear.  The next morning (Saturday) she woke up with a slight fever and feeling bad. She went and got tested and was positive.  She and her family all got exposed at her husbands family Christmas on Tuesday before Christmas. Apparently someone there was asymptomatic. So, with their party and then our Christmas gathering, we ended up having about 20 total people come down positive with symptoms 

. Luckily, everyone has had minor issues, and no respiratory problems. Worst problems have been with my wife’s parents, who are mid-to-late 80’s. They have been fatigued and had stomach distress, so won’t eat like they should.  Have to make sure they get nutrition and stay hydrated.
Anyway, that’s how easy it is to spread to a bunch of people quickly, even if you have no symptoms.
