title: Fever of unknown origin (FUO) due to Legionnaire's disease.
abstract: Fevers of unknown origin (FUOs) may be due to any of over 200 different disorders. We present a most unusual case of an FUO in a returning traveler from the Dominican Republic. Work-up for Q fever, Brucellosis, Bartonella, malaria and HIV were negative, but very highly elevated ESRs and ferritin levels suggested possible Legionnaire's disease. This is the third reported case of Legionnaire's disease presenting as an FUO.
