Government-wide takedown wave: CDC surveillance data, HIV tools, and survey materials go dark

Racing the OPM deadline, agencies removed or altered thousands of pages and datasets. At CDC, removals included BRFSS and YRBS data files, questionnaires, and codebooks; the AtlasPlus interactive tool (15 years of HIV, viral hepatitis, STD, and TB surveillance); historical HIV surveillance reports; HIV-prevention and LGBTQ-health topic pages; the Social Vulnerability Index and Environmental Justice Index; and NIAID's "HIV Language Guide." Census Household Pulse Survey files disappeared from FTP downloads; PEPFAR data dashboards, USAID's entire website, foreignassistance.gov, and the USAID-supported DHS international survey databases went offline. Contemporary analyses counted at least ~146 datasets removed from data.cdc.gov and well over 1,000 CDC pages affected; some pages returned February 1-2 bearing the banner "CDC's website is being modified to comply with President Trump's Executive Orders." The Williams Institute documented that within 10 days of January 20, BRFSS/YRBS datasets, Household Pulse data, and years of HIV/AIDS monitoring results had been deleted.
