Some federal health websites restored, others still down, after data purge

Scientists and public health leaders are taking stock of the Trump administration's abrupt decision to pull down web pages, datasets and selected information from federal health websites. Some of the pages on the Center for Disease Control and Prevention website that went offline have since reappeared. The Atlas Tool, used by policymakers to track rates of infectious diseases such as HIV and STIs, disappeared but now is back. Pages that explained the Youth Risk Behavior Surveillance System, which monitors adolescent health, were gone but can now be seen again. And the CDC's data site, which was taken offline over the weekend, is back up with datasets available for download. But there is uncertainty about what may be different.
