Case studies in international travelers.
Family physicians should be alert for unusual diseases in patients who are returning from foreign travel. Malaria is a potentially fatal disease that can be acquired by travelers to certain areas of the world, primarily developing nations. Transmitted through the bite of the Anopheles mosquito, malaria usually presents with fever and a vague systemic illness. The disease is diagnosed by demonstration of Plasmodium organisms on a specially prepared blood film. Travelers can also acquire amebic infections, which may cause dysentery or, in some instances, liver abscess. Amebiasis is diagnosed by finding Entamoeba histolytica cysts or trophozoites in the stool. Invasive amebic infections are generally treated with metronidazole followed by iodoquinol or paromomycin. Cutaneous larva migrans is acquired by skin contact with hookworm larvae in the soil. The infection is characterized by the development of itchy papules followed by serpiginous or linear streaks. Cutaneous larva migrans is treated with invermectin or albendazole. Case studies are presented.
