The Health in All Policies (HiAP) approach aims to integrate health into decisions across sectors to address the social determinants of health and enhance health equity. Jurisdictions interested in implementing this approach may seek clarification about how to operationalize it. Public health legal preparedness provides useful lessons for HiAP. While there are important differences between these two areas, there are also critical similarities. These similarities are particularly important because HiAP and public health preparedness are complementary. Law has been essential in advancing public health preparedness by helping to: (1) prioritize planning; (2) allocate responsibility; (3) enhance collaboration and coordination; (4) establish responsive funding; and (5) emphasize the needs of vulnerable populations. Law can be used similarly to advance HiAP.
