Study on the prevalence of parasitic infections in Thai laborers who applied for working abroad was carried out during 5 years. The total number of 78,240 stool specimens was obtained and examined by simple smear and iodine. It was found that the prevalence of parasitic infections from 1993 to 1997 was 12.15%, 13.13%, 12.57%, 4.62% and 5.76% respectively. The five most frequently parasites found in stool were Blastocystis hominis, hookworms, Giardia lamblia, Strongyloides stercoralis and Opisthorchis viverrini. Such findings were similar to previous reports, but in lower percentages. Thus, continuity of public health education and sanitation improvement should be concerned for prevention and control of parasitic infections.
