This condition occurs in many different areas of the world, but the largest endemic focus is in the southeastern and midwestern United States, where up to 80% to 90% of the population may exhibit a positive intradermal histoplasmin skin test.[1] Acute disseminated histoplasmosis, quite rare before the acquired immunodeficiency syndrome (AIDS) epidemic, is now much more common, occurring in 2.7% to 5% of AIDS patients in nonendemic areas and in up to 27% of AIDS patients in endemic areas of the United States.[2-4] Acute disseminated histoplasmosis often occurs early in the course of HIV infection and is the AIDS-defining illness in at least half of these cases.[5]
