A mouse in the house can be more than just a nuisance; a rodent infestation can be a serious threat to the health of yourself, your family, and your pets. Rats in New York City have been called “disease-sponges,” and wild mice are known for spreading the potentially fatal Hantavirus, resulting in outbreaks like the one at Yosemite a few years ago.   

It's important to understand the different mouse diseases that exist so you can keep your family safe. This article contains information on some of the possible diseases from mice to look out for around your home. 

What diseases do mice carry?

Beyond property damage, there are also health concerns to keep in mind if you have or suspect a mouse problem in your home. Don't dismiss these small creatures as harmless. Taking the proper measures will help control the mouse problem and prevent it from happening again in the future. 

These are some of the most common and most concerning rodent related illnesses that you should be aware of:

  • Hantavirus
    • A severe, sometimes fatal, respiratory disease transmitted when people breathe air contaminated by the virus. Contamination can occur when rodents shed the virus through their droppings, urine, or saliva.
    • Symptoms include fatigue, fever, muscle aches, coughing and shortness of breath.
    • There is no vaccine or cure; treatment consists of managing symptoms.
  • Lyme Disease
    • Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks which can be carried by rodents.
    • Symptoms include fever, rash, facial paralysis, and arthritis.
    • Most patients recover when treated with a few weeks of oral antibiotics, although some experience Chronic Lyme Disease or Post-treatment Lyme Disease Syndrome.
  • Colorado Tick Fever
    • A virus is spread to people through bites of infected ticks which can be carried by mice.
    • Symptoms include fever, chills, headache, body aches, and feeling tired. Some patients have sore throat, vomiting, abdominal pain, or skin rash.
    • There are no medications to treat Colorado Tick Fever; treatment consists of managing symptoms.
  • Babesiosis
    • Babesiosis is caused by microscopic parasites that infect red blood cells and are spread by certain ticks that can be carried by rodents.
    • Some people develop flu-like symptoms, such as fever, chills, sweats, headache, body aches, loss of appetite, nausea, or fatigue, but others show no symptoms. For the elderly or people with weakened immune systems, babesiosis can be severe and life-threatening.
    • People who do not have symptoms or signs of babesiosis usually don’t need treatment, but options are available. Please consult a medical professional.
  • Salmonella
    • Salmonella is a bacteria that makes people sick. It can be spread by eating or drinking foods that have been contaminated by rat feces.
    • Symptoms include diarrhea, fever, and abdominal cramps.
    • Most cases of salmonella will resolve themselves in a few days, but sometimes hospitalization is required to manage symptoms.
  • Rat-Bite Fever
    • Rat-bite fever is a disease that occurs in humans who have been bitten by an infected rat or, in some cases, squirrels, mice, cats, and weasels.
    • Symptoms include fever, chills, headaches, skin rash, vomiting, and other complications.
    • When treated promptly, antibiotics are usually effective.

If you suspect a mouse problem in your home and notice any of these symptoms from your family members, schedule a check-up to get it figured out as soon as possible. 

How to prevent mouse diseases and clean up after a mouse

Avoiding contact with rats and mice is the best way to protect your family from the above diseases. Take time to prevent pest problems in your home by sealing potential entry points such as cracks in your home’s foundation, gaps near doors, and damaged window screens. Maintain cleanliness to reduce available food and water sources for rodents. For example, store dry foods in air tight containers and use a covered trash can.

In addition to spreading disease, rats and mice can contaminate food and cause major property damage. If you do have a mouse in the house, use extra caution when cleaning up after it has been removed.
