An overall apparent prevalence of 11.4% of O.viverrini infections was found in the investigated population in Binh Dinh Province, Central Vietnam, which is considered a moderate prevalence. Among the individuals who declared having eaten raw fish dishes, the prevalence was 25.5%.
Although we were able to confirm O.v infection in only 11 of the 29 individuals shedding trematode eggs, our findings strongly suggest O.v infections in all those people.
