In order to study the prevalence of intestinal parasites among Japanese expatriates of developing countries, we conducted fecal specimen examinations annually from 1995 to 2000. Fecal specimens were collected from Japanese expatriates of each area: Asia, the Middle East, East Europe, Africa and Latin America. The specimens were fixed with 10% formalin in the local area, and then examined in Japan. We used the formalin-ether sedimentation method to find protozoan cysts or helminth eggs.<BR>In 1995, the infection ratio was 3.0% (N=981), decreasing to 2.4% (N=1, 275) in 1996, 2.3% (N=1, 620) in 1997 and 1.6% (N=1, 574) in 1998. However, the ratio began to increase in 1999 (2.0%, N=1, 713) and 2000 (2.5%, N=1, 806). The ratio in Africa was the highest in each year, followed by Asia and Latin America. Heterophyidae (51 cases), <I>Giardia lamblia</I> (42) and <I>Trichuris trichiura</I> (30) were detected most frequently. In Egypt, the ratio of Heterophyidae rose by 28.8% in 2000. This was the prime reason for the increase in the overall ratio of infections worldwide. Most of the Japanese infected with Heterophyidae in Egypt had ingested dried mullet roe. This may explain the reason for the increase in the infection ratio there.<BR>Although the prevalence of intestinal parasites among Japanese expatriates in developing countries is decreasing, those who eat fish in these areas are still at risk. In order to eradicate intestinal parasitosis from this group, we must continue preventive measures such as health education.
