Ever spotted a chipmunk darting across your yard? You might catch yourself wondering if these adorable critters can actually make people sick. Turns out, chipmunks do carry a handful of diseases, but they rarely pass them straight to humans. Most of the time, infections come from insects like fleas and ticks that hitch a ride on chipmunks—not from the animals themselves.
It’s good to know what’s a real risk and what isn’t. You don’t need to panic, but if you want to understand the diseases tied to chipmunks and how to avoid them, stick around.
How Chipmunks Carry and Transmit Diseases to Humans
Chipmunks spread diseases to people in a few ways. You might get sick by touching them or their droppings, getting bitten by their parasites, or coming into contact with places they’ve contaminated.
Knowing these things helps you avoid trouble with these little guys.
Direct Contact With Chipmunks and Rodent Droppings
Touching chipmunks or spots where they leave droppings and urine can expose you to disease. Those droppings might carry viruses and bacteria like hantavirus or leptospirosis.
If you touch contaminated stuff and then touch your mouth or face, you could get infected.
Try not to handle chipmunks or clean up after them without gloves and a mask. Even dead chipmunks can carry germs, so go easy.
Chipmunk bites or scratches might also spread infections. Best to keep your distance.
Vector-Borne Transmission: Ticks, Fleas, and Mites
Chipmunks often have ticks, fleas, and mites that bite humans and pets. Ticks that feed on chipmunks can carry Lyme disease bacteria.
If a tick bites you, it might pass on Lyme disease, which can show up as fever and aching joints.
Fleas riding on chipmunks sometimes spread plague, though that’s pretty rare. Mites can cause itchy skin or carry bacteria too.
These tiny pests jump from chipmunks to people or pets who get too close.
Using insect repellent and checking for ticks after being outside are smart moves to avoid these bugs.
Environmental Sources: Contaminated Water and Soil
Chipmunks sometimes contaminate soil and water with their urine and droppings. If you drink or use water from spots where chipmunks hang out, you could get diseases like tularemia or hantavirus.
These illnesses often happen when tiny particles from droppings get into the air or when you drink dirty water.
Skip drinking from untreated sources near chipmunk habitats. Wear gloves when gardening or cleaning where chipmunks might have been.
Cleaning up your space helps lower the risk of picking up something nasty from the environment.

Common Diseases Carried by Chipmunks
Chipmunks can carry all sorts of bacterial, viral, and parasitic diseases that might affect people. These illnesses usually spread through bites, contact with droppings, or by ticks and fleas that live on chipmunks.
It’s worth knowing about the main ones so you can stay safe.
Lyme Disease and Tick-Borne Illnesses
Chipmunks often have ticks infected with Borrelia burgdorferi, the bug behind Lyme disease. If a tick bites you after feeding on a chipmunk, you might get sick.
Early signs feel like the flu, with fever and sometimes a bullseye-shaped rash.
Chipmunks also host ticks that can spread other infections like anaplasmosis, babesiosis, and Colorado tick fever. These can cause fever, chills, and tiredness.
Check your body and clothes for ticks after spending time where chipmunks live. Wearing long sleeves and using repellent helps keep ticks away.
If you find a tick on your skin, take it off quickly and carefully. That lowers your risk of getting sick.
Plague, Tularemia, and Other Bacterial Infections
Chipmunks sometimes carry fleas with plague bacteria. Plague’s rare but can be serious, spreading mainly through flea bites.
Symptoms look a lot like the flu, with fever and swollen lymph nodes. Doctors can treat it if you catch it early.
Tularemia—or “rabbit fever”—is another infection tied to chipmunks. You might get it from touching chipmunk droppings or from a bite.
It brings on fever, skin sores, and swollen glands.
Other bacterial diseases to watch for include leptospirosis and rat-bite fever. These can spread through urine, saliva, or bites.
Washing your hands and steering clear of chipmunks is a good way to stay safe.
Hantavirus, Rabies, and Viral Diseases
Chipmunks don’t usually carry rabies, but if one bites you, there’s still a risk of infection. You’ll want to get treatment fast if that happens.
More often, chipmunks carry hantavirus. People can catch it by breathing in dust with their droppings or urine mixed in.
Hantavirus starts off with flu-like symptoms, but things can get worse pretty quickly—especially with breathing. If you spot chipmunk waste, don’t clean it up without some kind of protection.
Chipmunks also sometimes spread viruses like La Crosse virus and Colorado tick fever. Infected ticks or mosquitoes usually pass these on.
These viruses might give you a fever, headache, or even a rash. I’d say it’s smart to be careful around chipmunks and any rodent droppings.
