Overview
- Peer‑reviewed analysis in Annals of Internal Medicine reports 38 of 82 CDC datasets that had been updated at least monthly went stale in 2025, with most interruptions beginning in March–April.
- Roughly 87–90% of the paused systems tracked vaccination, with additional gaps in respiratory disease and drug overdose surveillance.
- A December 2025 recheck showed only one of the 38 paused databases had resumed, signaling prolonged disruptions.
- An HHS spokesperson said dashboard and schedule changes reflect routine data‑quality and system‑management decisions, not political direction.
- The study did not determine causes; public‑health experts and the editorial call for minimum transparency standards detailing reasons for pauses and timelines for resuming publication.
