The STOP TICKS Act reauthorizes federal efforts to combat tick-borne diseases by expanding and extending two existing programs through 2030. The bill broadens the Tick-Borne Disease Working Group to include thirteen federal agencies across agriculture, environmental protection, and defense rather than just seven agencies focused on health, allowing for more coordinated prevention and research efforts. It increases funding for regional centers of excellence studying vector-borne diseases from ten million to twelve million dollars annually, and increases funding to help state and local health departments address vector-borne diseases from twenty million to twenty-one million dollars annually. These funding increases apply to fiscal years 2026 through 2030, replacing the previous authorization period that ended in 2025. The legislation aims to improve coordination across the federal government and provide greater resources for tick-borne disease research, surveillance, and prevention nationwide.
