During the period January to December 1998, the National Malaria Center (CNM) carried out a parasitological survey of schoolchildren in rural and semi-urban areas, to assess intestinal helminthic infections in schoolchildren in the central parts of Cambodia. In the rural areas, there were four schools in Stung Treng Province (all situated along the Mekong River), five schools in Kratie Province (around rubber plantations), six schools in Kampong Chhnang Province (along Tonle Sap Lake); and in the semi-urban areas, three schools in Beng Tumpon Commune and five schools in Chbar Ampeou Commune (Mean Chey District) were selected for study. By Kato-Katz technique, the prevalence of soil-transmitted helminthic infections in schoolchildren in both the rural and urban areas was high. The infection rate was between 10-40% for Ascaris, 2-17% for Trichuris and 5-65% for hookworm. Schistosomiasis and opisthorchiasis were found in the schoolchildren living along the Mekong River (Stung Treng Province); the infection rate of S. mekongi ranged from 12 to 43%. These infections in children were with hepatomegalies. An intervention in an urban area (Chraing Chamres) showed that after repeated treatment with mebendazole 500 mg single dose every 6 months, the prevalence of all parasites had dropped to about one third of the initial level.
1998年1月至12月期间，国家疟疾中心（CNM）对农村和半城市地区的学童进行了寄生虫学调查，以评估柬埔寨中部地区学童的肠道蠕虫感染情况。在农村地区，上丁省有4所学校（均位于湄公河沿岸），桔井省有5所学校（在橡胶种植园周边），磅清扬省有6所学校（沿洞里萨湖）；在半城市地区，选择了崩通蓬公社的3所学校和占碑安博公社（棉芷区）的5所学校进行研究。通过加藤-厚涂片法，农村和城市地区学童土壤传播蠕虫感染的患病率都很高。蛔虫的感染率在10%至40%之间，鞭虫为2%至17%，钩虫为5%至65%。在湄公河沿岸（上丁省）生活的学童中发现了血吸虫病和华支睾吸虫病；湄公血吸虫的感染率在12%至43%之间。这些儿童感染伴有肝肿大。在一个城市地区（占碑占雷斯）进行的一项干预措施表明，每6个月单次服用500毫克甲苯达唑反复治疗后，所有寄生虫的患病率已降至初始水平的约三分之一。
