Tularemia is a rare infectious disease that typically attacks the skin, eyes, lymph nodes and lungs. Tularemia is also called rabbit fever or deer fly fever caused by the bacterium Francisella tularensis.
In the 1950s, thousands of people were infected each year. This number has dropped considerably, to less than 200 each year, and those who are infected now tend to be those who are exposed to the organism in its rural habitat.
Tularemia is treated with a drug called streptomycin. The drug is given intramuscularly, twice a day, for one to two weeks. Alternatively Gentamicin may be given intravenously.
The CDC has been investigating the cases and their possible causes, which include enterovirus D-68 (EV-D68), the source of a respiratory illness outbreak involving 1,116 cases in recent months, nearly all of them in children.
