Tularemia is a serious infectious disease caused by the intracellular bacterium Francisella tularensis. It is also known as Pahvant Valley plague, rabbit fever, deer fly fever, and Ohara's fever.
Serological investigations on hunters and healthy school children nevertheless indicate, with up to 4.7% positivity in the latter group, that Francisella tularensis low-grade infection is widespread
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.
