In order to investigate the status of intestinal helminthic infections in Cambodia, epidemiological surveys were carried out on a national scale, including 19 provinces. A total of 32,201 fecal samples were collected from schoolchildren and adults between 2006 and 2011 and examined once by the Kato-Katz thick smear technique. The overall egg positive rate of intestinal helminths was 26.2%. The prevalence of hookworms was the highest (9.6%), followed by that of Opisthorchis viverrini/minute intestinal flukes (Ov/MIF) (5.7%), Ascaris lumbricoides (4.6%), and Trichuris trichiura (4.1%). Other types of parasites detected were Enterobius vermicularis (1.1%), Taenia spp. (0.4%), and Hymenolepis spp. (0.2%). The northwestern regions such as the Siem Reap, Oddar Meanchey, and Banteay Meanchey Provinces showed higher prevalences (17.4-22.3%) of hookworms than the other localities. The southwestern areas, including Koh Kong and Preah Sihanouk Provinces showed higher prevalences of A. lumbricoides (17.5-19.2%) and T. trichiura (6.1-21.0%). Meanwhile, the central and southern areas, in particular, Takeo and Kampong Cham Provinces, showed high prevalences of Ov/MIF (23.8-24.0%). The results indicate that a considerably high prevalence of intestinal helminths has been revealed in Cambodia, and thus sustained national parasite control projects are necessary to reduce morbidity due to parasitic infections in Cambodia.
为调查柬埔寨肠道蠕虫感染状况，在全国范围内开展了流行病学调查，涵盖19个省份。2006年至2011年间，共收集了32201份学童和成人的粪便样本，并采用加藤厚涂片技术进行了一次检测。肠道蠕虫的总体虫卵阳性率为26.2%。钩虫的感染率最高（9.6%），其次是肝吸虫/微小肠吸虫（Ov/MIF）（5.7%）、蛔虫（4.6%）和鞭虫（4.1%）。检测到的其他寄生虫类型有蛲虫（1.1%）、带绦虫属（0.4%）和膜壳绦虫属（0.2%）。暹粒、奥多棉吉和班迭棉吉等西北地区的钩虫感染率（17.4 - 22.3%）高于其他地区。包括国公和西哈努克省在内的西南地区蛔虫（17.5 - 19.2%）和鞭虫（6.1 - 21.0%）的感染率较高。同时，中部和南部地区，特别是茶胶省和干丹省，Ov/MIF的感染率较高（23.8 - 24.0%）。结果表明，柬埔寨肠道蠕虫的感染率相当高，因此有必要持续开展全国性的寄生虫防治项目，以降低柬埔寨寄生虫感染导致的发病率。
