“…Infection is acquired by ingestion of undercooked cyprinoid's fish harboring infective metacercariae (Kaewkes 2003). Liver fluke is endemic among human populations in northeast and north Thailand, where the most common raw fish "Koi pla" is frequently consumed (Sadun 1955;Harinasuta and Vajrasthira 1960;Wykoff et al, 1965;Preuksaraj et al, 1982). Recent study, we found that O. viverrini infection was 1.25%, this result is lower than the previously survey in 2012.…”

“…Cats, dogs and rats are also definitive hosts for O. viverrini (Sadun, 1955). The relative contribution of these hosts to the transmission of the parasite to the intermediate snail hosts are not known but are considered minor compared with the higher egg excretion and hygiene behaviour of humans (Sadun, 1955).…”

Estimations of infection rates in these animals have not been studied and remain unknown for Lao PDR.…”

The objective was to document epidemiological features of O. viverrini infections in a highly endemic district. A random sample was selected (13 villages, 15 households/village, all household members aged >6 months). Clinical examinations, short interviews and stool examinations (Kato-Katz technique) were performed. Fish samples were dissected for the presence of metacercaria. In total, 814 persons were enrolled (median age 16 years, 51.5% women). The prevalence was 58.5%. Infection rates increased with age (from 20.0 to 85.5%; P < 0.001). Intensity of infection and the habit of consuming insufficiently cooked fish also increased with age. Of the study participants, 75.2% reported cooking fish insufficiently. Of the 23 different species of cyprinoid fish consumed in the study villages, 20 species were infected. At the village level, the prevalence of raw fish consumption was strongly associated with the infection status of O. viverrini (r = 0.76, P = 0.003). At individual level, age, the consumption of insufficiently cooked fish, and the absence of sanitation were strongly associated. The disease associated with O. viverrini infection needs to be assessed in order to develop and conduct adequate interventions. Epidemiology of

“…Human have been infected by ingesting under-cooked fish containing infective metacercariae, this is very common in the northeastern and northern region particularly in rural areas (Sadun 1995;Wykoff et al, 1966;Vichasri et al, 1982;Sithithaworn et al, 1997;Jongsuksantikul and Imsomboon 2003). Although, many program campaign has been operated in Thailand for reduced O. viverrini infection over period 1955-2000, the national prevalence of O. viverrini infection had fallen but the high prevalence rate is still found in the rural communities of provinces, Northeast (Jongsuksantikul and Imsomboon 2003;Sithithaworn et al, 2012).…”
