francisella tularensis is found in many animals (rabbits, rodents) and may be transmitted by direct contact or via insect Bite (ticks and deer-fly). Humans can also contract the illness via the direct contact with the infected animal carcass (break in the skin).
risk factors include an exposure to rabbits or recent tick bite. A vaccine is available for high risk workers. Treatment is with streptomycin or tetracycline. Tularaemia is fatal in 5% of untreated cases and in less than 1% of treated cases.
