Some of those counties in ID, MT, and SD that I know well don't have a hospital at all. And some that do have a BIA hospital .
One county in particular, that had ~2,500 residents at the last census and ~1,200 in 2017 expects 100 COVID-19 cases by May. Knowing the ranchers there, they are at high risk (old, comorbidities), stubborn, hard working, and shearing/lambing/calving season is coming so they have to overcome their natural tendency to practice "social distancing" and work together. I'm afraid it may wipe most of a county off the map this Spring.
