contagious disease

If you've been closely following the pandemic from the beginning (I hope you're enjoying the Prozac), it should be obvious how little we really knew about COVID a year ago. Social distancing? Did it really work? Maybe.
For those of you clinging to the idea that COVID-19 is nothing more than "the flu," an unfortunate (but entirely predictable) "experiment" in a bar in Florida should disabuse you of this myth.
As if winter isn't bad enough. Perhaps a visit from Santa might cheer you up, especially if you've already had a visit from Satan (note the brilliant juxtaposition of letters!).
The flu reminds us that humans, as social creatures, are more susceptible to contagious disease than more solitary species. But do other social species treat contagion differently and could there be evolutionary insights to discover?
