Tularemia is a rare bacterial infection. The effects of the infection will depend on where the exposure occurs. It can be deadly if not treated.

Tularemia is caused by specific bacteria. It is normally found in small animals, such as mice and rabbits. The bacteria can pass to humans through:

  • Bites of infected animals, ticks, or deer flies.
  • Contact with an infected animal's tissues or contaminated water, food, or soil. Can enter the body through the lungs, eyes, mouth, nose, or skin.

The infection does not pass between people.
