Lyme Disease

Rodents like chipmunks and mice are often infected by lice and ticks. These can infest human hair and spread diseases. Lyme disease, for instance, is a disease spread by ticks.

While chipmunks are not directly responsible for spreading the disease, the tick in their hair certainly is.


You may have heard of the Great Plague that spread across Europe in the 15th Century. If you do, then let us tell you that rodents have been the ones to blame. The rodent family can easily spread the epidemic.

In fact, the plague has not been eradicated yet. Various mammals carrying the disease are still alive. According to the California Department of Public Health, around five plague-ridden chipmunks were found around Lake Tahoe. This verifies that the disease is very much alive.

Leptospirosis is a bacterial disease that is spread by eating food or drinking water contaminated with the urine of the infected creatures. Infected animals may show no symptoms at all.

In humans, common symptoms include fever, headache, red eyes, chills, and muscle aches. Diarrhea, rashes, jaundice, and vomiting are some other symptoms of the disease.


Tularemia is a bacterial disease spread by eating or drinking contaminated food or water, by being bitten by an infected animal, or by handling a dead animal’s carcass.

You can prevent the disease by wearing gloves before handling an infected rodent and by using an insect repellent. Tularemia can be fatal. Fortunately, in most cases, it can be treated with antibiotics.

Make sure you report to your pet’s vet if your pet kills a chipmunk. Ensure you wash your hands thoroughly if you ever come in contact with a chipmunk.

Infection On Biting

A chipmunk bite is a rare phenomenon. However, the bite by a chipmunk is a serious situation. Infections include skin and tissue loss and even organ failure. Note symptoms like oozing, swelling, and fever, and immediately consult a doctor.

Preventing The Diseases
