The CDC has ordered a mass retraction and revision of submitted research across all science and medicine journals to remove certain banned terms.

The banned terms include 'gender,' 'transgender,' 'pregnant person,' 'LGBT,' and other related terms.

The policy affects manuscripts that are in the revision stages or already accepted for publication but not yet published.

The scale of the policy's impact is unclear, but it could affect many manuscripts that include demographic information.

The policy requires approval by a Trump political appointee for any public health communications, potentially causing delays.
