All people in the United States deserve the same level of public health protection, making it crucial that every health department across the country has a core set of foundational capabilities. Current research indicates an annual cost of $32 per person to support the foundational public health capabilities needed to promote and protect health for everyone across the nation. Yet national investment in public health capabilities is currently about $19 per person, leaving a $13-per-person gap in annual spending.To "create the conditions in which people can be as healthy as possible" and to protect national security, this gap must be filled. The Public Health Leadership Forum convened national experts in the public health, public policy, and other partner sectors to develop options for long-term, sustainable financing. The group aligned around core principles and criteria necessary to establish a sustainable financing structure.Informed by the work of the expert panel, the authors recommend a Public Health Infrastructure Fund for state, territorial, local, and tribal governmental public health, that would provide $4.5 billion of new, permanent resources needed to fully support core public health foundational capabilities.
