CDC Updates Public Health Data Strategy for 2024-2025: Faster Data Sharing & Threat Detection

Berlin – In a significant step towards bolstering national health security, the Centers for Disease Control and Prevention (CDC) has launched its updated Public Health Data Strategy for 2024-2025. This initiative, building on the foundation laid by the 2023 strategy, aims to modernize the nation’s public health data infrastructure, enabling faster detection and response to emerging health threats. The strategy focuses on seamless data exchange between healthcare organizations, public health authorities at all levels – state, tribal, local, territorial, and federal – and a more proactive and informed approach to safeguarding public health. The need for such modernization has become increasingly apparent in recent years, highlighted by the challenges faced during the COVID-19 pandemic and, more recently, outbreaks of measles and avian influenza.

At the heart of this effort is the recognition that timely and accurate data are critical for effective public health interventions. As CDC Director Mandy Cohen, M.D., M.P.H., stated, “Data are the oxygen that powers our ability to detect and respond to health threats. Early detection and monitoring of health threats rely on timely data in order for us to investigate and respond effectively.” The strategy directly advances the priorities of the CDC’s Data Modernization Initiative (DMI), translating broad goals into concrete, measurable milestones. This isn’t simply about collecting more data; it’s about improving the speed, quality, completeness, and accessibility of the information available to public health officials.

A key achievement highlighted in the 2023 Lookback Report, released alongside the updated strategy, is the substantial increase in electronic case reporting (eCR). More than 36,000 healthcare facilities now utilize eCR, a significant jump from the over 25,000 facilities reporting electronically in early 2023. This expansion allows for quicker transmission of crucial data to public health agencies, accelerating case investigations, outbreak identification, and exposure tracing, although simultaneously reducing the administrative burden on healthcare providers. The strategy also emphasizes expanding electronic laboratory reporting, with 90% of CDC labs now electronically sharing data with external partners, facilitating the rapid dissemination of critical information.

Accelerating Data Sharing and Modernization

The updated strategy for 2024-2025 builds on the successes of 2023, outlining priority areas for continued improvement. A central focus remains on accelerating the adoption of eCR, particularly among critical access hospitals (CAHs). Currently, 380 CAHs across the U.S. Have implemented eCR, up from approximately 300 in early 2023. Here’s particularly important as these hospitals often serve rural and underserved communities where timely data collection can be more challenging. Improved data access in these areas is crucial for identifying disease trends and implementing targeted interventions. The CDC is also prioritizing the connection of public health data systems to the broader health IT ecosystem, leveraging initiatives like the Trusted Exchange Framework and Common Agreement (TEFCA) to establish secure and efficient data sharing pathways with healthcare systems, and providers. Electronic case reporting is a cornerstone of this effort.

Beyond eCR, the strategy emphasizes expanding core data sources critical for early threat detection and real-time monitoring. This includes strengthening the exchange and sharing of data related to wastewater surveillance, hospitalizations, and hospital bed capacity. Integrating and visualizing these diverse data streams will provide a more comprehensive picture of public health trends, allowing for more informed decision-making. The CDC’s Respiratory Virus Data Channel, launched in September 2023, exemplifies this approach, offering data visualizations and up-to-the-minute findings on COVID-19, influenza, and respiratory syncytial virus (RSV). The channel has already garnered over 4 million visits, demonstrating the public’s appetite for accessible and timely health information. The Respiratory Virus Data Channel provides valuable insights into respiratory illness activity.

Addressing Health Equity Through Data

A crucial component of the updated strategy is a commitment to addressing health disparities and promoting health equity. The CDC recognizes that social determinants of health – factors like socioeconomic status, access to healthcare, and environmental conditions – play a significant role in health outcomes. The strategy includes milestones focused on increased reporting of data related to these social determinants, enabling the CDC and health departments to more effectively identify and address health inequities. This data-driven approach is essential for ensuring that public health interventions reach those who need them most and that all communities have the opportunity to achieve optimal health. The CDC’s commitment to health equity is reflected in its prioritization of data collection and analysis related to social determinants of health.

The National Syndromic Surveillance Program (NSSP) also plays a vital role in this data-driven approach. As of 2023, 78% of U.S. Hospital emergency departments (EDs) were providing data to the CDC within 24 hours through NSSP. This real-time reporting allows public health departments to detect and monitor a wide range of health threats, from infectious diseases like influenza to non-infectious threats such as heat waves, wildfires, and opioid overdoses. The ability to rapidly identify and respond to these diverse threats is a testament to the power of syndromic surveillance. The CDC continues to work with state and local partners to expand NSSP coverage and improve data quality.

Looking Ahead: Continued Investment and Collaboration

The CDC’s Public Health Data Strategy is not a static document; it is a living framework that will continue to evolve as recent challenges and opportunities emerge. The updated strategy for 2024-2025 lays out a clear roadmap for continued investment in data modernization, emphasizing the importance of collaboration between public health agencies, healthcare providers, and technology partners. The success of this strategy hinges on a shared commitment to data sharing, interoperability, and the employ of data to inform public health decision-making. The CDC is actively working with stakeholders across the country to implement the strategy and achieve its ambitious goals.

The ongoing measles outbreak, with 378 confirmed cases across 15 states and two deaths reported in Texas as of March 20, 2025, serves as a stark reminder of the importance of robust public health data systems. As Department of Health and Human Services Secretary Robert Kennedy recently stated, “The measles outbreak in Texas is a call to action for all of us to reaffirm our commitment to public health.” Effective surveillance, rapid case investigation, and targeted vaccination campaigns all rely on timely and accurate data. The CDC’s data modernization efforts are essential for preventing future outbreaks and protecting the health of the nation.

The next major checkpoint for this initiative is the release of the 2024 Lookback Report, expected in early 2026, which will assess progress made against the 2024-2025 milestones.
