Keep tick disease tracking running through 2030

3 min readLast updated September 5, 2026

Why it matters

Five more years — that's what S. 2398 gives federal tick- and vector-borne disease programs that would otherwise age out after 2025. If you live where Lyme disease and other vector-borne illnesses are a growing concern, this bill keeps the national strategy, research hubs, and health department support in place through 2030.

S. 2398 keeps federal tick- and vector-borne disease programs from expiring after 2025 by extending them through 2030.

One part of the bill continues the national vector-borne disease strategy and the regional centers of excellence that support research and coordination. Another part continues enhanced federal support for state, local, and tribal health departments dealing with these diseases.

That means the bill is mainly about continuity, not a brand-new program. If Congress passes it, the same core federal framework for tracking, planning, and responding to tick-borne disease stays in place for five more years.

The bill also makes one substantive process change: instead of specifically naming the Tick-Borne Disease Working Group in the consultation language, it tells the Health and Human Services secretary to work with "appropriate individuals." That gives the department more flexibility, but it also removes one named body from the statute.

It makes another wording change by saying the secretary acts "through" federal agencies rather than "in coordination with" them. That does not create a new benefit for patients on its own, but it may clarify which agencies are directly responsible for carrying out the strategy.

What you would notice most is not a new program or new check — it's that federal disease surveillance and support do not hit a legal stop after 2025.

S. 2398 Bill Summary

What S. 2398 actually does.

1

National tick disease strategy keeps going

S. 2398 extends the federal national strategy for vector-borne diseases through 2030 instead of letting the current authorization end after 2025.

2

Regional research hubs stay in place

The bill keeps the regional centers of excellence on vector-borne diseases authorized for another five years, preserving the federal structure for research and coordination.

3

Health departments keep federal support

State, local, and tribal health departments would remain eligible for enhanced federal support on vector-borne disease work through 2030.

4

Named tick working group is removed from the law

The bill drops the Tick-Borne Disease Working Group from the consultation language and replaces it with a broader requirement to consult "appropriate individuals."

5

HHS gets clearer implementation language

S. 2398 changes how the Health and Human Services secretary carries out the strategy, saying the department acts through federal agencies rather than in coordination with them.

Who benefits from S. 2398?

Communities in tick-prone areas

People in places where tick-borne illness is a recurring health risk would benefit from uninterrupted federal surveillance, planning, and response work through 2030.

State, local, and tribal health departments

These agencies keep the federal authorization behind their vector-borne disease support for five more years instead of facing a 2025 cutoff.

Researchers and public health labs

The regional centers of excellence and national strategy framework stay in place through 2030, giving ongoing research and coordination efforts more continuity.

Patients who rely on early detection and response

You would not get a direct payment or benefit card, but you could benefit if continued surveillance helps spot outbreaks, improve reporting, or guide faster local response.

Who is affected by S. 2398?

The Health and Human Services Department

HHS would keep running these programs through 2030 and would follow revised language on how it consults experts and works through federal agencies.

The Tick-Borne Disease Working Group

This group would no longer be explicitly named in the statute's consultation requirement, even though the department could still consult relevant experts.

Federal agencies involved in vector-borne disease work

Agencies helping carry out the national strategy would continue under the reauthorized framework through 2030.

Taxpayers and budget writers

S. 2398 extends existing authorities but does not name a new dollar amount in the bill text provided, so future appropriations decisions would still shape the programs' actual funding level.
