CDC director Rochelle Walensky announces shake-up of the organization, citing COVID mistakes

The head of the nation's top public health agency on Wednesday announced a shake-up of the organization, saying it fell short responding to COVID-19 and needs to become more nimble.

The planned changes at the Centers for Disease Control and Prevention — CDC leaders call it a "reset"— come amid criticism of the agency's response to COVID-19, monkeypox and other public health threats. The changes include internal staffing moves and steps to speed up data releases.

The CDC's director, Dr. Rochelle Walensky, told the agency's staff about the changes on Wednesday. It's a CDC initiative, and was not directed by the White House or other administration officials, she said.
