Molecular evidence of a high prevalence of Opisthorchis viverrini infection in an endemic community in Sakon Nakhon Province, northeastern Thailand

This study demonstrates that O. viverrini infection remains highly prevalent in rural communities of northeast Thailand. Molecular diagnosis was more sensitive than conventional microscopy and key demographic risk factors were identified. These findings underscore the need for active surveillance and provide valuable data to guide and strengthen future prevention and control strategies for O. viverrini and other helminth infections in the region.
