Flying Blind: Public Health Without Population Data
On January 31, 2025, federal health agencies began removing thousands of webpages and datasets from public access in response to executive orders from the Trump Administration targeting "gender ideology" and diversity, equity, and inclusion initiatives. By February 1, over 8,000 federal webpages and 450 government domains had gone dark, including critical public health resources from the Centers for Disease Control and Prevention (CDC), National Institutes of Health (NIH), and Food and Drug Administration (FDA).
Immunologist and microbiologist Dr. Andrea Love, Executive Director of the American Lyme Disease Foundation, minced no words regarding the executive actions: "If you weren't clear: a President ordering a Federal health and disease agency to delete pages on its website is a public health crisis." The scope of removed content spans decades of population health data, from the 40-year-old Youth Risk Behavior Surveillance System to current HIV surveillance statistics. Many pages that have returned now display banners warning of further modifications, creating uncertainty around the future availability and integrity of federal health data.
This sudden removal of public health information echoes similar challenges faced during the early COVID-19 response, when limited access to comprehensive population data hampered the ability to identify and address emerging health disparities. As we examine the current situation, the key question becomes: How can evidence-based public health function without access to the very data that drives decision-making and ensures equitable health outcomes?
Scale of Impact
The removal of federal health datasets represents an unprecedented disruption to public health surveillance and research capabilities. According to KFF analysis, key resources taken offline include:
The CDC's Youth Risk Behavior Surveillance System, which for 40 years has tracked critical health indicators among high school students. This dataset has been instrumental in identifying emerging health crises, including the rise in youth mental health challenges and substance use patterns.
CDC's AtlasPlus tool, containing nearly 20 years of surveillance data for HIV, viral hepatitis, sexually transmitted infections, and tuberculosis, is no longer accessible. This platform has been essential for tracking disease trends and designing targeted prevention strategies.
The Social Vulnerability Index and Environmental Justice Index - critical tools for identifying communities at heightened risk during public health emergencies and environmental disasters - have also been removed. These resources help public health officials allocate resources effectively during crises and natural disasters.
Public health researchers report that the loss of demographic data collection and analysis capabilities particularly impacts their ability to identify and address health disparities.
As Dr. Jennifer Nuzzo, director of the Pandemic Center at Brown University School of Public Health notes, "Health equity is basically all of public health."
The ability to analyze health outcomes across different populations is fundamental to developing effective interventions and ensuring equitable access to care.
The CDC's healthcare provider resources have also been affected, including treatment guidelines for sexually transmitted infections and HIV prevention protocols. This loss of clinical guidance materials creates immediate challenges for healthcare providers working to deliver evidence-based care.
Beyond individual datasets, this wholesale removal of public health information disrupts the interconnected nature of federal health data systems. Many of these resources inform each other, creating compounding effects when multiple datasets become unavailable simultaneously.
Research and Care Delivery Impact
The removal of federal health data creates immediate challenges for both research and clinical care delivery. The Infectious Diseases Society of America (IDSA) warned that removing HIV and LGBTQ+ related resources from CDC websites "creates a dangerous gap in scientific information and data to monitor and respond to disease outbreaks."
This impact is particularly acute in STI prevention and treatment. Including gender and demographic data in research helps identify populations at elevated risk for infections like syphilis, which has reached its highest levels in 50 years. Without this data, developing targeted interventions becomes significantly more challenging.
For HIV prevention specifically, the loss of CDC's AtlasPlus tool removes access to critical surveillance data that guides prevention and treatment strategies. Healthcare providers report that missing CDC clinical guidance on HIV testing and PrEP prescribing creates uncertainty in delivering evidence-based care.
David Harvey, executive director of the National Coalition of STD Directors, emphasizes the immediate clinical impact: "Doctors in every community in America rely on the STI treatment guidelines to know what tests to run, to know what antibiotic will work on which infection, and how to avoid worsening antibiotic resistance. These are the guidelines for treating congenital syphilis, for preventing HIV from spreading, and for keeping regular people healthy every time they go to the doctor."
The loss of demographic data collection capabilities also threatens to undermine decades of progress in understanding and addressing health disparities. Research requiring analysis of health outcomes across different populations may face delays or compromised results without access to comprehensive federal datasets.
This disruption extends beyond immediate clinical care to impact long-term research projects and clinical trials. FDA guidance documents about ensuring diverse representation in clinical studies are no longer accessible, potentially affecting the development of new treatments and their applicability across different populations.
Historical Context and Implications
The current removal of federal health data follows concerning precedent. During the COVID-19 pandemic, similar actions to restrict access to public health data hampered effective response. In July 2020, hospital COVID-19 data reporting was moved from CDC control to a private contractor, leading to significant gaps in data access and accuracy that impeded pandemic response.
As Harvard epidemiologist Nancy Krieger notes, "There's been a history in this country recently of trying to make data disappear, as if that makes problems disappear... But the problems don't disappear, and the suffering gets worse."
This observation proved accurate during COVID-19, when limited access to comprehensive demographic data delayed recognition of disparate impacts on communities of color.
Early COVID-19 response efforts were hampered by insufficient data about how the virus affected different populations. This information gap contributed to delayed identification of emerging hotspots and slowed targeted intervention efforts. The result was preventable disparities in COVID-19 outcomes, particularly among Black, Hispanic, and Native American communities.
Today's wholesale removal of federal health data risks recreating similar blind spots across multiple public health challenges. Without demographic data to identify disparities and guide interventions, public health officials lose the ability to effectively target resources and measure outcomes. As Dr. Jennifer Nuzzo emphasizes, this data is "really important for us to answer the essential question of public health, which is, Who is being affected and how do we best target our limited resources?"
Legal Response and Policy Challenges
On February 4, 2025, Doctors for America filed suit against multiple federal agencies including the Office of Personnel Management (OPM), Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), and Department of Health and Human Services (HHS).
The lawsuit challenges two key actions: OPM's directive requiring agencies to remove webpages and datasets, and the subsequent removal of critical health information by CDC, FDA, and HHS. The complaint argues these actions violated both the Administrative Procedure Act and the Paperwork Reduction Act of 1995 (PRA).
Under the PRA, federal agencies must "ensure that the public has timely and equitable access to the agency's public information" and "provide adequate notice when initiating, substantially modifying, or terminating significant information dissemination products." The complaint alleges agencies failed to provide required notice before removing vital health information and datasets.
The legal challenge emphasizes the fundamental role these datasets play in public health. According to the filing, "The removal of the webpages and datasets creates a dangerous gap in the scientific data available to monitor and respond to disease outbreaks, deprives physicians of resources that guide clinical practice, and takes away key resources for communicating and engaging with patients."
Nine out of twelve public health researchers on CDC's advisory board signed a letter to the agency's acting director seeking explanation for the data removal. These scientists expect to face consequences for speaking out but emphasize the critical nature of maintaining public access to health data.
Data Preservation Efforts
As federal health datasets disappeared, researchers and institutions launched rapid preservation efforts. Harvard University organized its first "datathon" to archive website content through the Wayback Machine, while other academic institutions worked to preserve datasets locally.
The Kaiser Family Foundation reports having downloaded significant portions of CDC data prior to removal. While some CDC data files have been restored, they currently lack essential documentation like questionnaires and codebooks needed for analysis.
For healthcare providers needing immediate access to clinical guidelines, medical associations are working to provide archived copies of treatment protocols. The Infectious Disease Society of America and HIV Medicine Association are coordinating with members to ensure continued access to critical clinical resources.
State health departments maintain some parallel data collection systems that may help fill gaps in federal surveillance. However, these systems often rely on federal frameworks for standardization and analysis, potentially limiting their utility as standalone resources.
These preservation efforts, while necessary, cannot fully replace the coordinated federal data infrastructure needed for comprehensive public health surveillance and research.
Recommendations
Healthcare providers and public health officials should consider these immediate steps to ensure continued access to vital health information:
Data Access and Preservation
Download and securely store copies of restored CDC datasets, including documentation
Maintain offline copies of current clinical guidelines and protocols
Establish relationships with academic institutions archiving federal health data
Alternative Data Sources
Connect with state and local health departments to access regional surveillance data
Utilize medical society and professional organization resources for clinical guidance
Consider participating in alternative data collection networks being established by research institutions
Advocacy Actions
Support ongoing legal efforts to restore data access
Document specific impacts of data loss on care delivery and research
Engage with professional organizations coordinating preservation efforts
Future Planning
Develop contingency plans for maintaining essential health surveillance
Build redundant data collection systems where feasible
Strengthen partnerships with academic and nonprofit research organizations
These steps cannot fully replace federal health data infrastructure but may help maintain critical public health functions while broader access issues are resolved.
Bipartisan Hepatitis C Elimination Plan Presents Critical Lame Duck Opportunity
The presidential election results have created an urgent six-week window for advancing the National Hepatitis C (HCV) Elimination plan. With significant changes to federal healthcare policy likely under the incoming administration, Senators Bill Cassidy (R-LA) and Chris Van Hollen (D-MD) see the lame duck session as a critical opportunity to secure this public health initiative. The legislation's prospects benefit from Senator Cassidy's likely chairmanship of the Senate Health, Education, Labor and Pensions (HELP) Committee in the next Congress, providing potential continuity for implementation oversight despite the broader administrative transition.
The Congressional Budget Office's analysis provides compelling economic justification for swift action. Current estimates indicate between 2.5 and 3.0 million people in the United States are living with HCV, yet only one in three people diagnosed receive treatment within 12 months. This treatment gap resulted in over 14,000 deaths from HCV-related complications in 2020 alone - deaths that could have been prevented with existing curative treatments that demonstrate 95% effectiveness.
The scope of this crisis demands federal intervention. State-level efforts, while demonstrating potential, have proven insufficient for achieving elimination goals. The Cassidy-Van Hollen legislation addresses fundamental barriers beyond medication costs, including provider education, treatment infrastructure, and implementation support. These comprehensive elements, combined with projected long-term savings, position this bill as a rare opportunity for bipartisan achievement in public health policy during a period of political transition.
Economic Analysis Reveals Complex Implementation Challenges
The Congressional Budget Office's June 2024 analysis examines two treatment expansion scenarios among Medicaid enrollees, revealing both significant savings potential and implementation complexities. Under a conservative 10% peak increase in treatment rates, averted healthcare spending would reach $0.7 billion over ten years against $0.5 billion in testing and treatment costs. A more aggressive 100% peak increase could generate $7 billion in averted costs against $4 billion in treatment expenses.
These projections, however, exclude critical implementation costs that could significantly impact program effectiveness. The CBO notes successful expansion requires substantial investment in outreach activities, provider education, and infrastructure development. As treatment rates increase, identifying and engaging people who need treatment becomes progressively more complex and costly - a challenge demonstrated by state-level experiments with subscription models.
Louisiana's program illustrates both the potential and limitations of cost-focused approaches. While reducing projected costs from $760 million to $35 million annually and treating over 1,600 people since 2019, treatment rates have steadily declined. Washington state's experience proves more concerning - treatment rates fell below pre-subscription levels, dropping from 6,649 prescriptions in 2017 to 2,409 in 2021.
The CBO's analysis particularly focuses on Medicaid enrollees, noting this population includes many people at elevated risk for HCV, including people who inject drugs and people who have been involved with the criminal justice system. This targeted approach allows for more precise cost projections while addressing a key demographic in HCV elimination efforts. Notably, the standard 10-year budget window may undervalue long-term benefits, as many health complications from untreated HCV develop over decades.
State experiences reveal important lessons for federal policy design. Washington's planned initiatives - including emergency room screening programs, mobile testing units, and expanded clinic access - remained largely unrealized due to budget constraints. Louisiana's model, despite demonstrating viable cost-control mechanisms, approaches expiration without renewal funding. These outcomes emphasize the need for sustained federal support rather than relying on state-level innovation.
Carceral Settings Reveal Critical Implementation Lessons
Treatment access in prisons provides critical insight into healthcare system readiness for HCV elimination. Despite controlled environments ideal for treatment delivery, systematic failures in carceral settings expose fundamental weaknesses in current approaches. Between 2014-2019, 1,013 people died from HCV-related complications while incarcerated, with the prison death rate reaching 10.0 per 100,000 people by 2019 - more than double the 4.3 per 100,000 rate in the general population.
State-level data reveals how policy choices, rather than medical constraints, drive treatment disparities. Florida reported 7,000 untreated cases in 2021 despite court-ordered treatment expansion. Texas provided treatment to only half of its known HCV-positive population of 11,301-15,563 people. Oklahoma's statistics prove particularly alarming - its prison death rate of 71.9 per 100,000 exceeds its general population rate by more than five times, despite the corrections department requesting nearly $100 million for increased treatment.
Recent investigations have catalyzed improvements in several states' treatment protocols. The FDA's 2024 approval of point-of-care testing technology enables rapid diagnosis and treatment initiation in carceral settings. However, implementation remains inconsistent across state systems, with many maintaining restrictive eligibility criteria that delay treatment until people develop severe liver damage. Texas, for example, still lacks universal screening protocols at intake facilities, leaving countless cases unidentified and untreated.
Legal challenges have prompted some progress. Florida, under court order, treated over 3,000 people between 2018 and 2021. Texas agreed to treat at least 1,200 people annually following a 2020 settlement. However, these court-mandated improvements highlight both the potential for rapid treatment expansion and the need for comprehensive federal policy to ensure consistent care delivery.
These systemic failures in controlled environments underscore broader implementation challenges. If consistent HCV treatment proves difficult in settings with stable populations and established healthcare infrastructure, addressing treatment gaps in the general population requires even more robust support systems and sustained funding commitments.
Implementation Barriers Demand Federal Solutions
Provider engagement represents a critical barrier beyond cost reduction. Despite HCV treatment's relative simplicity compared to managing diabetes, primary care providers often hesitate to initiate treatment. A recent study found that while 94% of specialists prescribe HCV treatment, only 23% of primary care providers do so. Insurance authorization processes exacerbate this reluctance - a single prior authorization request consumes 35 minutes of staff time responding to questions often designed to find denial justifications rather than facilitate treatment.
Geographic barriers particularly impact rural communities. In Louisiana, people in certain parishes travel 50-70 miles to reach HCV treatment providers. This distance barrier disproportionately affects people receiving Medicaid who often lack reliable transportation. Rural provider shortages compound these access issues - many rural clinics lack staff trained in HCV care, while others face chronic understaffing that limits capacity for managing complex prior authorization requirements.
Louisiana's experience highlights how workforce challenges undermine treatment expansion even when medication costs are controlled. The state's STI, HIV, and Hepatitis Program struggles with chronic understaffing due to uncompetitive wages and complex contracting arrangements. These staffing limitations directly impact program effectiveness - outreach activities decrease, patient engagement suffers, and treatment initiation rates decline despite medication availability.
The proposed federal legislation addresses these systemic barriers through targeted investments in:
Provider education and ongoing support programs
Infrastructure development for treatment expansion
Resources for patient engagement and retention
Support for innovative delivery models including mobile clinics
Integration with existing healthcare systems and substance use treatment programs
Workforce development and training initiatives
Early state experiences demonstrate that successful implementation requires simultaneous investment across these domains. Washington's inability to realize planned initiatives - including emergency room screening programs and mobile testing units - despite cost controls highlights the need for comprehensive federal support beyond medication access.
Political Window Demands Swift Advocacy Action
The lame duck session presents a rare confluence of political factors favoring HCV elimination policy. Senator Cassidy's likely ascension to HELP Committee chair in the next Congress, combined with his partnership with Senator Van Hollen, bridges current and future implementation efforts. The CBO's projection that a national elimination program could prevent 24,000 deaths and save $18.1 billion in healthcare costs provides compelling economic justification for swift action.
Recent developments strengthen the case for immediate passage. The FDA's approval of point-of-care testing technology enables rapid diagnosis and treatment initiation, particularly in high-impact settings. Louisiana's subscription model expiration creates urgency for federal intervention to sustain successful state initiatives. These factors, combined with potential changes to federal healthcare policy under the incoming administration, make the current legislative window critical for securing comprehensive HCV elimination policy.
The evidence from state experiences demonstrates both the promise and limitations of isolated initiatives. Federal legislation can build on these lessons, providing comprehensive support for implementation while ensuring sustained political commitment through bipartisan leadership. With only weeks remaining in the current congressional session, advocates must emphasize the unique opportunity this moment presents for achieving significant public health progress.
Conclusion
The opportunity for action is narrow, but the potential impact is immense. The bipartisan momentum behind the National Hepatitis C Elimination plan is a chance to advance public health policy at a time when it is desperately needed. The barriers are clear: implementation challenges, provider hesitancy, and geographic and economic obstacles. Yet the solutions are within reach, and the economic and human benefits are undeniable. Federal intervention can address the systemic gaps that state efforts alone cannot fill, providing comprehensive support to save lives and reduce costs.
However, uncertainty looms over the future of public health funding and support under a second Trump Administration, which looks to bring significant changes to federal healthcare priorities. This adds urgency to the current push for bipartisan action.
As advocates, the time to push is now. The lame duck session represents a rapidly closing window to secure funding, address legislative gaps, and ensure continuity into the next Congress. Swift passage of this legislation would not only demonstrate the power of bipartisan collaboration but also offer a meaningful legacy—one that saves thousands of lives and sets a precedent for effective, equitable public health initiatives in the United States. We cannot afford to let this window close without taking action.
