CDC Director Dr. Rochelle Walensky tested positive for COVID-19 again on Sunday, 10 days after initially contracting the virus.
Walensky, who is up to date on her vaccines, started a course of Pfizer’s antiviral drug Paxlovid when she first started developing symptoms on Oct. 21.
Her symptoms improved and she tested negative, but she tested positive again in an apparent rebound case on Sunday.
