How Do You Get Diseases From Rodents?

To start off, rats and mice will never meet your expectations as far as cleanliness is concerned. Being around them could easily put your health at risk for numerous diseases. So how exactly do rodents transmit diseases to humans?

Through Their Waste

If you do have a rodent in your home, you will probably come across rodent fecal matter at one point or another. What you should know is that rat dropping will easily make you sick, the same goes for urine. Oftentimes you’ll find rodent urine in places where they’ve decided to mark their territories. You should know that you can catch diseases from mice waste even if you are careful not to touch them. To learn more about how to properly clean up rodent waste, click here.

From Other Pests

Rodents like mice and rats are just like any other wild animal. Being in the outdoors, rodents are susceptible to their own pests. Rodents can carry pests that have hitched a ride onto their body into your homes. Some of these pests carry even more diseases that can be transmitted along with other issues.

For example, the Bubonic plague is transmitted by fleas that have been found on mice’s skin and fur. Not to mention, those pests that they bring in can lead to a whole other infestation. This is a great concern to homeowners and especially those who have pets.

Through Bites

Rodents don’t usually tend to bite unless they’re experiencing some kind of threat. However, if you’re unlucky enough to get bitten by a rodent such as a rat, then you are likely to catch the rat-bite fever. Bites transmit diseases through saliva. But what’s worse is that you don’t even have to get bitten to contract the disease. Just touching a dead mouse that has been infected or eating and drinking foods that have been contaminated by rats could potentially expose you to the disease.

Common Rodent Related Diseases

Rodent-related diseases are not as common as other diseases which makes people complacent when it comes to getting rid of these pests. But knowledge is power — the more you know the more you’ll be able to protect yourselves. Here are some common diseases that come from rodents.


This disease was first discovered in the southwest part of the United States. Predominantly transmitted through deers, white-footed rats, cotton rats, and also rice rats; the Sin Nombre Hantavirus. Similar to other rodent-related diseases, the Hantavirus is not common but does cause kidney, respiratory, and blood ailments in humans. Through mouse droppings, urine and also stirred up nesting material — it can cause the disease to be airborne and transmitted to human beings. Symptoms begin as early as one week post-infection and the related symptoms include the following;

  • Abdominal pain
  • Dizziness
  • Fatigue
  • Muscle pain
  • Fever

Lymphocytic Choriomeningitis LCM

The Lymphocytic Choriomeningitis Virus (LCMV) is what causes this viral disease. Predominantly found in mice, this particular disease has been found in approximately 5% of all house mice. The mode of transmission for LCMV is similar to the Hantavirus disease. It mainly occurs by coming into contact with mouse saliva, dropping or shuffling the nest of infected mice. Inhaling the contents, or even exposing broken skin can transmit the disease. The LCMV infection occurs in two stages where the first stage causes symptoms like:  

  • Muscle aches
  • Loss of appetite
  • Nausea
  • Fever

The second stage is more severe. Symptoms associated with the second stage includes:

  • Sensory disturbance
  • Meningitis
  • meningoencephalitis


This infamous disease killed millions of people across Europe during the middle ages. The Plague doesn’t only affect humans but also other mammals as well. The bacteria Yersinia Pestis is what causes this disease. Transmission to humans results from handling a dead animal infected by the plague or a bite from an infected rodent flea. There are different types of plague that may infect humans. Here are the main symptoms;

  • Fever
  • Chills
  • Extreme weakness


Unfortunately, this rare disease affects both animals and humans. Oftentimes, rodents infected with Tularemia die in huge numbers, especially rabbits. Ingesting water and food contaminated with the virus is how humans can get the disease. There are different forms of this disease. However, most cases are easily treated when caught early on. Often the mode of infection will determine the symptoms you experience but the most common symptom is fever. Other symptoms include:

  • Skin ulcers
  • Swollen & painful lymph glands
  • Inflamed eyes
  • Pneumonia
  • Throat & mouth sores
