Explains why Utah has less than 1% confirmed case fatality ratio while KY has 4.98%
In the article accompanying the map:
"In collaboration with Microsoft Healthcare NeXT and CareJourney, Dartmouth Atlas has also issued data about the regions in the U.S. with Medicare beneficiaries over the age of 65 who have two or more chronic conditions—the people most vulnerable to developing severe cases of COVID-19."
I believe the map is color-coded to show general public over age 65 with 2 or more chronic conditions, AND NOT (covid) patients with two or more underlying conditions. I believe the writers are inferring that those areas could see high death rates among that population should covid get a toe-hold in those commnities.
