Intestinal parasites in Southeast Asian refugees.

A survey of intestinal parasitism in 6,241 Southeast Asian refugees (3,576 males and 2,665 females) indicated that 32.9 percent of the refugees had one or more intestinal parasites. A total of 1,178 (57.3 percent) males and 878 (42.7 percent) females harbored the parasites, with helminths representing the most frequent isolate. Intestinal parasitic infections may be considered minimal public health threats in the United States because of effective hygienic practices and sanitation facilities. However, it is important to emphasize that the attack rate also will be influenced by continued health education, job activities, and diagnosis and treatment of the refugees for these parasites.
