Intestinal parasites: diagnostic and treatment guidelines.

The incidence of intestinal parasite infection is on the increase in the United States due, in part, to the recent entry into this country of more than 500,000 Southeast Asian refugees. Most symptoms of parasitic infections are nonspecific and many infected individuals are asymptomatic. Stool specimens are used to identify the specific organism. Treatment, which varies depending on the infecting organism, is presented. Patient education especially in the area of hygiene is important to prevent reinfection.
