title: Eosinophilia in the returning traveler.
abstract: The most common cause of eosinophilia in the traveler returning from the developing world is from infection with a helminth parasite. Protozoal, bacterial, and fungal infections are uncommon causes of eosinophilia. Allergic disorders and drug reactions must also be considered, as well as numerous uncommon miscellaneous disorders. This article reviews the diagnostic features of the more common causes of eosinophilia in the returned traveler and suggested drug treatment.
