So, if you visit two thanksgiving gatherings, and you’ve seen none of the people involved in weeks, your odds of transmitting a contagious disease from one gathering to another is very low to nonexistent?
I suppose that would depend on fomites on clothing and such, wouldn’t it.

That depends on the virus, but generally speaking, COVID and other respiratory viruses don't seem to survive longer than 3 days on surfaces in ideal conditions and degrade much, much faster in the natural environment. There is even some evidence your skin naturally serves somewhat of a disinfectant and kills flu virus pretty rapidly ( https://academic.oup.com/cid/article/48/3/285/304169).
That being said, you should still wash your hands.
