The type of information that has been withheld has previously been vital to hospitals, health officials and local leaders on the front lines providing updated guidance on how to treat, test and slow the spread of the illness, which has claimed over 200,000 American lives. A source told ABC News that includes additional “guidance on who should be tested and when,” adding, “That stuff won’t get updated.”

From at least Sept. 24 to Sept. 30, the CDC has stopped updating new health guidance and recommendation information, according to the sources. An ABC News review of the CDC website shows a timeline that supports the lack of information being updated.

­­A CDC source familiar with the COVID response called the halt in information flow to the American public a “moratorium,” adding, “Scientists are prevented from updating the CDC website with new information, recommendations and policies surrounding COVID.” A separate source confirmed CDC guidance updates are not currently being published, but disagreed with the categorization of a “moratorium” and instead insisted “agency leadership is just ensuring the review process is being followed.”
