Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis.[4] Symptoms may include fever, skin ulcers, and enlarged lymph nodes.[3] Occasionally, a form that results in pneumonia or a throat infection may occur.[3]

The bacterium is typically spread by ticks, deer flies, or contact with infected animals.[4] It may also be spread by drinking contaminated water or breathing in contaminated dust.[4] It does not spread directly between people.[8] Diagnosis is by blood tests or cultures of the infected site.[5][9]

Prevention is by using insect repellent, wearing long pants, rapidly removing ticks, and not disturbing dead animals.[6] Treatment is typically with the antibiotic streptomycin.[9] Gentamicin, doxycycline, or ciprofloxacin may also be used.[5]

Between the 1970s and 2015, around 200 cases were reported in the United States a year.[7] Males are affected more often than females.[7] It occurs most frequently in the young and the middle aged.[7] In the United States, most cases occur in the summer.[7] The disease is named after Tulare County, California, where the disease was discovered in 1911.[10] A number of other animals, such as rabbits, may also be infected.[4]
