Abstract

The purpose of this report is to compare the prevalence of Opisthorchis viverrini/minute intestinal fluke (Ov/MIF) in Lao People's Democratic Republic according to different regions and evaluate the effect of ingestion of raw freshwater fish on the infection. Demographic data, behavioral data, and symptoms were obtained, and the Kato-Katz method was used for the diagnosis of Ov/MIF. In total, 3,046 individuals were enrolled. The risk factors associated with acquisition of Ov/MIF were raw fish consumption and province. Khong Island showed the highest prevalence (odds ratio = 80.1, 95% confidence interval = 47.9-133.9, P < 0.001) compared with other districts, and raw fish consumption was related to Ov/MIF infection. Administration of praziquantel to entire populations, education (avoiding consumption of raw food dishes and improved hygiene), and access to clean water and sanitation should be considered.
