I'll probably skip all the holiday gatherings this year. I did last year, due to similar concerns. Around October 2019 I began experiencing most of the symptoms later associated with COVID-19, other than the fever. It was miserable and went on and on for months. I wasn't sure whether it was a virus or severe allergies, so I discontinued group bike rides, monthly dinner gatherings and holidays. Turned out to be allergies, finally relieved with new inhalers this spring.
I've done a few casual small group rides since summer, with folks who are conscientious about health issues and aren't coronavirus denialists. There's still some risk but fairly small. But I've still skipped the monthly dinner gatherings and will skip indoor holiday gatherings this year. Depending on the weather we might do a small outdoor get together.
