Prevalence of intestinal parasitic infections among Asian female house keepers in Abha District, Saudi Arabia.

A group of 5,518 female Asian house keepers working in Abha District of Saudi Arabia was examined (1990 through 1992) to determine the prevalence of intestinal parasitic infections. They came from Indonesia, Sri Lanka, Philippines and Thailand. Fresh stool specimens were obtained in special containers and examined by light microscopy of wet smears in normal saline and Lugoll's iodine solution within one hour of collection. The study revealed an overall prevalence of 46.5% which was higher than that reported among the Saudi population. The common parasites found included Trichuris trichiura (28.8%), Ascaris lumbricoides (22.2%), Hookworm (14.9%), Enterobius vermicularis (0.8%), Strongyloides stercoralis (0.6%), Entamoeba histolytica (1.2%), Hymenolepis nana (0.2%), and Giardia intestinalis (0.1%). The prevalence of intestinal parasites was statistically different among various studied nationalities. The possibility of spreading such diseases throughout the community should be considered in the light of the nature of work of this group being in close contact with different family members. It is recommended that all expatriate workers be checked and treated if necessary on arrival for the first time or from vacation. This policy must be strictly monitored, particularly for female house keepers.
