Causes of Tularemia

Though it’s rare, but some people can get sick with tularemia. It’s not a disease that naturally occurs in humans. It often affects rabbits and other animals including sheep, rodents, and birds. House pets like dogs and cats can get tularemia too.

Some ways people can get tularemia includes:

  • Contact with skin, meat, hair, of infected animals
  • Insect bites especially from a deer fly or tick
  • Consuming contaminated food or water
  • Inhaling bacteria that comes up from the soil during an activity like construction or gardening

Also, it is possible for a person to get infected if they are exposed to bacteria in a lab. Tularemia is most common in rural settings where animals are more likely to be infected with the bacteria. The bacteria can survive in soil, and dead animals for weeks. The mode of infection determines the type of symptoms you’ll experience.
