Hantavirus is a rare but potentially lethal disease spread by deer mice and white-footed mice. It has a mortality rate of 38 percent. Hantavirus can be spread through mouse saliva, urine, or feces. Transmission through mouse bites is rare. Usually, people develop it through airborne transmission.” – Healthline

Lymphocytic Choriomeningitis

Lymphocytic choriomeningitis is a viral disease carried by rodents. “It’s estimated that 5 percent of house mice in the United States carry lymphocytic choriomeningitis. It can be transmitted to humans through saliva, blood, feces, or urine.” – Healthline

If the infection spreads, it can lead to more serious conditions like meningitis. Meningitis is an infection of the tissue that lines your spinal cord and brain.

Rat-bite Fever

Rat-bite fever is a type of infection carried by bacteria that live on some rodents. It can be transmitted through bites or by consuming food and water contaminated with rodent feces or urine.” – Healthline

There currently aren’t any laboratory tests that can tell whether a mouse is carrying the bacteria that causes rat-bite fever, so a doctor may provide you with antibiotics before an infection develops.

  • vomiting
  • headache
  • muscle pain
  • joint swelling or pain 
  • rash

“Antibiotics are highly effective at curing rate-bite fever if it’s treated quickly. If not treated, the mortality rate is more than 10 percent.” Healthline

What to do next.

Were you bitten by a mouse in or around your home or business? It won’t be the last time – mice do not just go away on their own. In fact, given the right home and access to food, mice will multiply by the hundreds in just a short time. The longer a mouse infestation is allowed on your property, the greater the chances of mice bites and resulting infections.
