Of special concern is how the CDC has defined its low risk "green" category. Previously a county reached "low transmission" when there were under 10 new weekly cases per 100,000.
The new "low" level does take cases into account, but has raised the threshold substantially.
According to the new map, as long as hospital metrics are low, a county is green with any number up to 200 weekly cases per 100,000 people.

"It's extraordinarily high," says Malaty Rivera. "Everybody that I know in the infectious disease space is kind of gobsmacked by that shift."
