“The Delta variant is showing every day its willingness to outsmart us,” Walensky said at a news conference.
The president of the United States also spoke about the change. Joe Biden said increased use of masks and more vaccines in areas affected by the Delta variant of the coronavirus are the best ways to prevent a return to the lockdowns the country faced last year.
The change comes at a time when the Delta variant causes an increase in cases, especially in regions that register lower rates of vaccination. More transferable, the variant represents 90% of new infections in the United States.
