ABSTRACT
A health survey was carried out among residents of 33 villages under the Phitsanulok Irrigation Project Area, Nan River Basin, Northern Thailand, whereby general health conditions were examined including intradermal tests for schistosomiasis japonica, stools for intestinal parasites and sera tested by circumoval precipitin test for antibodies to S. japonicum and by agglutination test for leptospiral infection. Health investigations revealed that 913 (60.9%) of 1,499 people examined had experienced gastro-intestinal disorders, 254 (17%) had poor oral hygiene and a few had mild anemia. 799 (62%) of 1,298 examined had intestinal parasites. Hookworm (45%) was most common, followed by Opisthorchis viverrini (20%), Entamoeba coli (10%), Ascaris lumbricoides (6%), intestinal flukes (2%), Enterobius vermicularis (1%) and Giardia lamblia (1%). 149 (10%) of 1,422 people gave positive skin reaction to crude S. japonicum antigen. Circumoval precipitin test was strongly positive in 7 (1.6%) persons out of 449 tested for schistosome infection and 6 (4.0%) out of 1,358 people were positive for leptospiral infection. The significant endemic diseases as potential health problems in this water resources development are discussed.
