Omicron mostly mild so far, CDC chief says
Nearly every case of the omicron variant found in the U.S. has been mild, according to the chief of the federal Centers for Disease Control and Prevention (CDC).
More than 40 infections have been identified, and more than 75% of those had been previously vaccinated, according to Dr. Rochelle Walensky, director of the CDC.
“What we generally know is the more mutations a variant has, the higher level you need your immunity to be. … We want to make sure we bolster everybody’s immunity,” Walensky told Associated Press in an interview Wednesday. “And that’s really what motivated the decision to expand our guidance,” Walensky said, referencing the recent approval of boosters for all adults.
Reported symptoms have remained mostly cough, congestion and fatigue. One person has been hospitalized, and no deaths have been reported, CDC officials reported.
