Is Lyme Disease Common in Kentucky? Deer Mice and Tick Exposure
More than half of mice tested carried Lyme bacteria
Rodents may contribute to tick exposure patterns
Lyme disease in Kentucky may be changing
Questions about lyme disease in Kentucky continue to grow as researchers identify infected ticks and animal reservoirs in areas previously considered lower risk. Understanding whether deer mice and other rodents contribute to tick exposure may help explain how Lyme disease ecology changes over time.
Researchers reported that more than 50% of mice sampled in Kentucky carried Lyme bacteria, raising concerns about the potential role of rodents in maintaining local transmission cycles.
Is Lyme disease common in Kentucky?
Search interest around lyme disease in Kentucky reflects growing awareness that tick-borne illnesses may be expanding geographically.
Although Kentucky has historically been considered lower risk than some Northeastern states, surveillance studies suggest tick populations and infected animal reservoirs may be increasing.
Local ecology matters because infected wildlife hosts may help sustain tick populations capable of transmitting infection.
Are there deer mice in Kentucky and do they carry Lyme disease?
Yes. Deer mice and other rodents are found throughout Kentucky and may contribute to tick exposure cycles.
Rodents serve as hosts for immature ticks and may contribute to maintaining Lyme bacteria in the environment. Their role is less about directly infecting humans and more about sustaining ecological cycles involving ticks and wildlife hosts.
Search interest around deer mice in Kentucky reflects growing concern about whether local rodents contribute to tick exposure and Lyme disease ecology.
Do mice carry Lyme disease?
Mice themselves do not directly transmit Lyme disease to people. Instead, rodents may act as reservoir hosts, allowing feeding ticks to acquire bacteria and later spread infection to humans.
This distinction is important when discussing do mice carry Lyme disease because the relationship involves complex interactions among rodents, ticks, wildlife, and environmental factors.
Why rodent studies matter for tick exposure
Rodent surveillance studies provide early warning signs for changing Lyme disease patterns.
If infected rodents become more common in a region, tick populations feeding on those hosts may increasingly carry pathogens, potentially affecting local exposure risk.
Understanding these ecological relationships may improve prevention strategies and surveillance efforts.
Frequently Asked Questions
Is Lyme disease common in Kentucky?
Lyme disease has historically been less common in Kentucky than in Northeastern states, but evidence suggests tick exposure patterns may be changing.
Are there deer mice in Kentucky?
Yes. Deer mice and other rodents are widely distributed throughout Kentucky and may participate in tick-host cycles.
Do mice carry Lyme disease?
Mice act primarily as reservoir hosts that support infected ticks rather than directly spreading Lyme disease to humans.
How do rodents contribute to tick exposure?
Rodents provide blood meals for immature ticks and may help maintain Lyme bacteria within local ecosystems.
Clinical Perspective
Rodent surveillance studies offer insight into changing Lyme disease ecology. Monitoring infected wildlife hosts may help identify shifting geographic patterns before increases in human disease become obvious.
Clinical Takeaway
Evidence of infected rodents in Kentucky suggests clinicians and residents should remain aware of evolving tick exposure patterns and regional Lyme disease risk.

The mouse study was done entirely at WKU’s Green River Reserve, so it’s a bit of a stretch to extend the results to all of Kentucky. Nevertheless, the conclusion is probably correct: a new survey of blacklegged ticks off deer found Borrelia infection in many KY counties. https://www.sciencedirect.com/science/article/pii/S1877959X1730571X
Thanks for sharing. Studies of mice in New York from one location showed the tick borne infections were prevalent across a broad area.
We have patients from all over KY contacting us, KY Lyme Disease Association, that have confirmed Lyme disease. Our LLMD’s are fed up with KY for not doing more. We have to send patients out of state because UofL and UK continue to teach their doctors that Lyme is NOT in KY. Our whole family has Lyme and up and down our road, people have Lyme. Doctors do not recognize symptoms here and our LLMD’s are getting flooded.
Thanks for sharing your frustration. The paper addressed in my Lyme Disease Science blog adds evidence that there is a problem in Kentucky.
My 7 yr old daughter was diagnosed with Lyme disease monday september 10th 2018. I live in Trigg county kentucky in a rural area by Lake Barkley. She has the bulls eye rash in 2 places. Tomorrow we go for lab testing in a county nearby. Me and my husband are so scared we don’t know where to take her to ensure she gets the best treatment available please any advice is welcome. Thank you to anyone with help or advice for reading my comment!
I am another resident of Kentucky that has been diagnosed with Lyme . Northern Kentucky. I am sure that ticks carrying tickborne diseases are just cruising through the Ohio River Valley, which basically runs from Pennsylvania to the Mississippi river. In my area I know of almost 40 people fighting lyme or ” after damage”. We have all had to go out of state for treatment.
My granddaughter had two very small ticks on her back I got them out but the second one I don’t think I got the head out they were very itchy once I removed them the spots were still itchy but the night before last she said she was feeling dizzy while she was laying down she laid in bed half of the day which is not normal for her and last night she didn’t go to sleep until 2am the spots are swollen but no bulls eye Does this sound like a tick bite that needs medical attention?
Your daughter should be evaluated. Lyme disease should be considered even without a rash even if the tests are normal.
