Legislation extends key federal initiatives and programs to combat tick-borne diseases through 2030.
WASHINGTON, D.C. – Today, U.S. Senator Susan Collins announced that the Kay Hagan Tick Reauthorization Act, which she introduced with Senator Tina Smith (D-MN), with Senator Angus King joining them as an original cosponsor, has been signed into law.
Cases of Lyme disease have reached a new record level in Maine every year since 2022, with more than 4,200 cases reported statewide last year.
The Kay Hagan Tick Reauthorization Act confronts this growing public health threat by reauthorizing federal initiatives and programs to combat tick-borne diseases first established through the original Kay Hagan Tick Act, which Senators Collins and Smith led to passage in 2019. The Senators named their bill in honor of the late Senator Kay Hagan (D-NC), who passed away in October of 2019 due to complications from the tick-borne disease known as the Powassan virus.
“With Maine continuing to experience record levels of Lyme disease, we must continue working to address the growing threat posed by tick-borne diseases,” said Senator Collins. “The Kay Hagan Tick Reauthorization Act builds on the progress we have made in combatting these diseases since the original law was enacted and ensures this important work can continue across the country. I am grateful to Senator Smith for her partnership in this effort and to our colleagues in both chambers for working with us to move this important legislation across the finish line, and I am pleased to see it now signed into law.”
Using a three-pronged approach, the Kay Hagan Tick Reauthorization Act will:
- Reauthorize Regional Centers of Excellence in Vector-Borne Diseases through Fiscal Year 2030. These Centers have led the scientific response against tick-borne diseases, which now make up approximately 75 percent of vector-borne diseases in the U.S. There are four centers: at the University of Massachusetts Amherst, the University of California–Davis, the University of Florida, and the University of Wisconsin–Madison. The authorization for the program under the Kay Hagan Tick Act expired at the end of Fiscal Year 2025.
- Reauthorize CDC Grants to State Health Departments. These grants help departments improve data collection and analysis, support early detection and diagnosis, improve treatment, and raise awareness of vector-borne diseases. Reauthorizing these awards will help states continue building and maintaining a public health infrastructure for Lyme and other vector-borne diseases and amplify their initiatives through public-private partnerships. Since 2019, this funding has helped increase the number of health departments reporting tick-surveillance data from 6 to 44.
- Require the Department of Health and Human Services (HHS) to continue implementing and updating, as appropriate, its National Public Health Strategy to Prevent and Control Vector-Borne Diseases in People. This strategy has been integral in expanding research into tick-borne diseases, improving testing and diagnostics, and coordinating efforts across the federal government.
