“There’s increasing data that suggests that most of transmission is happening indoors rather than outdoors — less than 10% of documented transmission in many studies have occurred outdoors,” Walensky said. “We also know that there’s almost a 20-fold increased risk of transmission in the indoor setting.”

“Coupled with the fact that we now have 37% of people over the age of 18 fully vaccinated, and the fact that our case rates are now starting to come down, motivated our change of guidance.”
