Bottom Line: In the 3 villages, the overall positive rate for helminth eggs ranged from 51.7 to 59.0% (av. 57.4%), and the percentage positive for O. viverrini was 46.4-50.6% (47.5%).Other helminths detected included hookworms (13.2%), echinostomes (2.9%), Trichuris trichiura (1.3%), Ascaris lumbricoides (0.6%), and Taenia spp. (0.06%).Men (50.4%) revealed a significantly higher (P=0.02) prevalence than women (44.3%).

ABSTRACT
Opisthorchis viverrini infection was found to be highly prevalent in 3 riverside villages (Ang Svay Chek A, B, and C) of the Prey Kabas District, Takeo Province. This area is located in the southern part of Cambodia, where the recovery of adult O. viverrini worms was recently reported. From May 2006 until May 2010, fecal examinations were performed on a total of 1,799 villagers using the Kato-Katz thick smear technique. In the 3 villages, the overall positive rate for helminth eggs ranged from 51.7 to 59.0% (av. 57.4%), and the percentage positive for O. viverrini was 46.4-50.6% (47.5%). Other helminths detected included hookworms (13.2%), echinostomes (2.9%), Trichuris trichiura (1.3%), Ascaris lumbricoides (0.6%), and Taenia spp. (0.06%). The prevalence of O. viverrini eggs appeared to reflect a lower infection in younger individuals (<20 years) than in the adult population (>20 years). Men (50.4%) revealed a significantly higher (P=0.02) prevalence than women (44.3%). The Ang Svay Chek villages of the Prey Kabas District, Takeo Province, Cambodia have been confirmed to be a highly endemic area for human O. viverrini infection.

Figure 1: Map showing the surveyed area (Ang Svay Chek villages, Prey Kabas District) in Takeo Province, southern Cambodia.

Mentions: The surveyed regions included 3 villages (Ang Svay Chek A, B, and C) in the Prey Kabas District, an area approximately 45 km south of Phnom Penh (Fig. 1). Nearly 45,000 people reside in this District. Most villagers are farmers or fishermen. During the actual survey times (May 2006, November 2008, and May 2010), a total of 1,799 fecal samples were collected from the subjects (aged 1 though 94 years), 1 sample per each person, and transported to the Centre for Parasitology, Entomology, and Malaria Control in Phnom Penh, Cambodia. The Kato-Katz thick smear technique was used to detect helminth eggs. Fecal examinations of the villagers were sanctioned by the Ministry of Health, Cambodia, under the agreement of the Korea-Cambodia International Collaboration on Intestinal Parasite Control in Cambodia (2006-2011). Prevalence differences between men and women were statistically determined using the z-test.
