What is tularemia?
Tularemia is a potentially serious illness that occurs naturally in the United States. It is caused by the bacterium *Francisella tularensis* found in animals (especially rodents, rabbits, and hares).
What are the symptoms of tularemia?
Symptoms of tularemia may include:
Sudden fever
Chills
Headaches
Diarrhea
Muscle aches
Joint pain
Dry cough
Progressive weaknessPeople can also develop pneumonia with chest pain, cough, and difficulty breathing.
Other symptoms of tularemia depend on how a person was exposed to the tularemia bacteria. These symptoms can include ulcers on the skin or mouth, swollen and painful lymph glands, swollen and painful eyes, and a sore throat.

How does tularemia spread?
People can get tularemia many different ways:
Being bitten by an infected tick, deerfly or other insect
Handling infected animal carcasses
Eating or drinking contaminated food or water
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. People who have been exposed to the tularemia bacteria should be treated as soon as possible. The disease can be fatal if it is not treated with the right antibiotics.

How soon do infected people get sick?
Symptoms usually appear 3 to 5 days after exposure to the bacteria, but can take as long as 14 days.

What should I do if I think I have tularemia?
Consult your doctor at the first sign of illness. Be sure to let the doctor know if you are pregnant or have a weakened immune system.

How is tularemia treated?
Your doctor will most likely prescribe antibiotics, which must be taken as directed by your doctor to ensure the best possible result. Let your doctor know if you have any allergy to antibiotics.
A vaccine for tularemia is under review by the Food and Drug Administration and is not currently available in the United States.

What can I do to prevent becoming infected with tularemia?
Tularemia occurs naturally in many parts of the United States. Use insect repellent containing DEET on your skin, or treat clothing with repellent containing permethrin, to prevent insect bites. Use care and wear gloves when handling sick or dead animals. Be sure to cook your food thoroughly and that your water is from a safe source. Note any change in the behavior of your pets (especially rodents, rabbits, and hares) or livestock, and consult a veterinarian if they develop unusual symptoms.

Can tularemia be used as a weapon?
*Francisella tularensis* is very infectious. A small number (10-50 or so organisms) can cause disease. If *F. tularensis* were used as a weapon, the bacteria would likely be made airborne for exposure by inhalation. People who inhale an infectious aerosol would generally experience severe respiratory illness, including life-threatening pneumonia and systemic infection, if they are not treated. The bacteria that cause tularemia occur widely in nature and could be isolated and grown in quantity in a laboratory, although manufacturing an effective aerosol weapon would require considerable sophistication.

What is CDC doing about tularemia?
CDC operates a national program for research into the epidemiology and natural ecology of tularemia as well as the development of improved diagnostic tests. CDC serves as a reference laboratory for the United States and a World Health Organization (WHO) collaborating center for tularemia. Additional things CDC is doing related to bioterrorism preparedness include stockpiling antibiotics to treat infected or exposed people and educational programs for health professionals, the public and the media.
