@Leeroy Jenkins , you had posted about a local uptick in COVID cases in your orbit. Have all or most of those people's COVID cases run their course by now? Know anyone that was bad off from a recent case of COVID?

I thought this was interesting. We've heard about deer catching and spreading COVID amongst themselves. We've also known that humans and deer can spread it to each other, cross-species. What's weird, though, is cross-species spread without contact -- people not around deer catching deer-incubated sequences (at least if I'm reading the article correctly).
Researchers also found humans have likely spread the virus to deer at least hundreds of times.

From the article:
Several of these viruses appear to still be mutating and spreading between deer, including the Alpha, Gamma, and Delta variants of concern that drove an increase in deaths earlier in the pandemic, long after these lineages were subsumed by the wave of Omicron variants that continue to dominate nationwide.
Eighteen of the samples had no "genetically close human SARS-CoV-2 sequences within the same state" reported, foiling efforts to track down a precursor variant in humans.
"Overall, this study demonstrated that frequent introductions of new human viruses into free-ranging white-tailed deer continued to occur, and that SARS-CoV-2 VOCs were capable of persisting in white-tailed deer even after those variants became rare in the human population," the study's authors wrote.
Three had mutations that match a distinctive pattern of first spilling over from a human to deer, and then later another so-called "spillback" from deer back into humans. Two of these spillback variants were in North Carolina and one was in Massachusetts.
An investigation with the Centers for Disease Control and Prevention was able to track down three people who were infected by a variant with this hallmark deer mutation, as well as a handful of zoo lions who were also infected by the same strain.
None of the humans said they had close contact with either deer or the zoo.
