What is tularemia?
Tularemia is an illness caused by the bacteria Francisella tularensis. It is also called deer-fly fever or rabbit fever. The bacteria that cause tularemia are often found in animals, such as rodents, birds, reptiles, and fish. The bacteria can survive for weeks at low temperatures in water, moist soil, hay, and straw.

Tularemia is not spread from person to person. You may become infected through any of the following:
- Direct contact by touching the skin, tissues, or fluids of an infected animal. You may also get the disease from any tools that come into contact with an infected animal.
- Food and water that has come into contact with the bacteria. Infected animals can spread the bacteria to water through their urine.
- Breathing in infected dust or spray. This may happen when you mow, harvest, or sweep areas where infected animals have lived or died. You may also breathe in the bacteria if you work with it, such as in a lab.
- Insect bites from ticks, flies, or mosquitoes that have bitten an infected animal. When the insect bites you, the bacteria may be passed to you.
