The Centers for Disease Control and Prevention resumed publishing its weekly scientific report Thursday after an unprecedented pause, but information about the bird flu virus that was supposed to appear remained on hold even as the outbreak spreads.

The CDC on Thursday published its famed Morbidity and Mortality Weekly Report for the first time since the Trump administration ordered the nation’s various health agencies to freeze public communications.

Jan. 31, the CDC's chief science officer sent an internal email that informed the agency’s division heads that all papers written or co-written by CDC scientists are being withdrawn and that agency scientists should take their names off of papers they are collaborating on with external scientists, Reuters reported.

Scientists are struggling to respond to a Trump administration order to review papers already submitted for publication for content now banned by the federal government, according to interviews with six researchers.
