Dr. Rochelle Walensky says new mask-wearing guidance, coupled with higher rates of vaccination against COVID-19, could halt the current escalation of infections in “a couple of weeks.”

The director of the Centers for Disease Control and Prevention told “CBS This Morning” she hopes more stringent mask-wearing guidelines and other measures won’t be necessary as the country heads into the fall.

“We can halt the chain of transmission,” she said. “We can do something if we unify together, if we get people vaccinated who are not yet vaccinated, if we mask in the interim, we can halt this in just a matter of a couple of weeks.”
