What causes tularemia?

Tularemia is caused by the bacterium Francisella tularensis found in animals (especially rodents, rabbits, and hares).[1][2]

Humans can get the disease through:[1][2]

  • Direct contact, through a break in the skin, with an infected animal or its dead body
  • The bite of an infected tick, horsefly, or mosquito
  • Eating infected meat (rare)
  • Breathing in the bacteria, F. tularensis

Tularemia is not known to be spread from person to person. People who have tularemia do not need to be isolated.[2]
