From May to June 2011, we conducted stool surveys in riparian
villages of Kratie Province, Cambodia under the agreement of the
Korea-Cambodia International Collaboration Project on Intestinal
Parasite Control in Cambodia (2006–2011). The survey revealed
considerably high prevalence of O. viverrini infection among residents
and schoolchildren of two villages. Adult flukes were
recovered in 2 egg-positive cases and metacercariae were detected
in the fish hosts. Here, we report that O. viverrini is endemic in
riparian villages of Kratie Province, a mid-eastern part of Cambodia,
through which the Mekong River flows.
