Cross-sectional survey shows high prevalence of opisthorchiasis in an endemic community in Thailand, suggesting urgent surveillance and control strategies are needed.
Key Points
To investigate the epidemiology of Opisthorchis viverrini infection in a northeastern Thailand community.
Cross-sectional survey in Kusuman District, Sakon Nakhon Province
Used microscopic and molecular diagnostic methods
Collected demographic and behavioral data via standardized questionnaire
Performed stool sample analyses using Kato-Katz and PCR techniques
Microscopy detected 10.2% intestinal helminth infections, with O. viverrini at 6.1%
PCR identified a 19.9% prevalence of O. viverrini, tripling microscopy results
Being male associated with higher infection odds (aOR 5.55)
Aged 41–60 years had lower odds of infection (aOR 0.08)
