Widespread human SARS-CoV-2 infections combined with human–wildlife interactions create the potential for reverse zoonosis from humans to wildlife. We targeted white-tailed deer ( Odocoileus virginianus ) for serosurveillance based on evidence these deer have angiotensin-converting enzyme 2...

Been sitting on this paper after reading it last week. Some unexpected findings in there that bring up a lot of questions and concerns.
-The paper shows that white tailed deer populations in the northern US states have a very high prevalence of sero-positivity to SARS-COV-2. Meaning that they caught SARS-COV-2 in the past.
-They looked at historical blood samples and the seropositivity correlates well with the start of the pandemic in 2020, so cross-reactivity is not likely. Still makes me wonder, because these are not PCR tests where they specifically identified the virus, but the identification of antibodies that bind SARS-COV-2. But that correlation in time is hard to overlook.
-We're talking about high prevalence here: 67% of deer in MI, 44% in PE, 31% in NY and 7% in IL.
-So what the fuck is going on? How did deer catch this? And then how did they spread it to each other or did they? They spend their time outside and are mostly solitary. Could there be a common infection source, say drinking water? And what the hell, Michigan?
-Biggest issue with this is that there is now a documented natural source for SARSCOV2. So even if we eradicate in humans, it can always return. Are there other animal reservoirs? Minks come to mind.
