The Public Health Funding Restoration Act aims to significantly bolster national investment in public health by fully funding the Prevention and Public Health Fund (PPHF). This legislation amends the Patient Protection and Affordable Care Act to mandate an annual appropriation of $2,000,000,000 for the PPHF, effective for fiscal year 2026 and all subsequent fiscal years. The bill emphasizes that the PPHF is crucial for supporting core prevention efforts at federal, state, local, Tribal, and territorial health departments. These funds are vital for preventing and controlling infectious diseases, injuries, and chronic conditions, as well as for evidence-based initiatives such as tobacco cessation, nutrition, mental health, and immunizations. Congress finds that investments in prevention are highly effective, reducing healthcare costs and saving lives, with every dollar spent on prevention potentially saving nearly six dollars in health spending. By restoring and sustaining this funding, the Act seeks to enable the Centers for Disease Control and Prevention and other health agencies to invest in innovative, evidence-based public health programs, thereby enhancing the nation's capacity to respond to public health threats and help avoid future pandemics and epidemics.
