To reauthorize the Kay Hagan Tick Act, and for other purposes.

H.R. 4348, introduced July 10, 2025, would reauthorize key programs under the Kay Hagan Tick Act focused on tick- and vector-borne disease prevention, surveillance, and public health capacity. The bill extends and clarifies authorizations for two main elements: (1) the National Strategy and Regional Centers of Excellence in Vector-Borne Disease (under the Public Health Service Act, section 317U) and (2) enhanced support to health departments addressing vector-borne diseases (section 2822(c)). It updates who may participate in related activities by replacing a reference to a specific Tick-Borne Disease Working Group with the broader phrase “appropriate individuals,” and it broadens language to emphasize increasing capacity to identify, report, prevent, and respond to vector-borne diseases. Importantly, the authorizations are extended from the 2021–2025 window to 2026–2030, signaling continued federal support for tick- and vector-borne disease initiatives through 2030. In short, the bill aims to ensure ongoing federal funding and direction for coordinated national strategies, regional centers of excellence, and state/public health department support to combat tick-borne diseases, while broadening participation and capacity-building efforts.
