New CDC director takes over beleaguered agency amid crisis

NEW YORK — As the coronavirus swept across the globe last year, the Centers for Disease Control and Prevention sank into the shadows, undermined by some of its own mistakes and stifled by an administration bent on downplaying the nation’s suffering.

Now a new CDC director is arriving to a mammoth task: reasserting the agency while the pandemic is in its deadliest phase yet and the nation’s largest-ever vaccination campaign is wracked by confusion and delays.

“I don’t know if the CDC is broken or just temporarily injured,” but something must be done to bring it back to health, said Timothy Westmoreland, a Georgetown University law professor focused on public health.

The task falls to Dr. Rochelle Walensky, 51, an infectious-diseases specialist at Harvard Medical School and Massachusetts General Hospital, who was sworn in Wednesday. She takes the helm at a time when the virus’s U.S. death toll has eclipsed 400,000 and continues to accelerate.

While the agency has retained some of its top scientific talent, public health experts say, it has a long list of needs, including new protection from political influence, a comprehensive review of its missteps during the pandemic and more money to beef up basic functions like disease tracking and genetic analysis.

Walensky has said one of her top priorities will be to improve the CDC’s communications with the public to rebuild trust. Inside the agency, she wants to raise morale, in large part by restoring the primacy of science and setting politics to the side.
