Opisthorchis viverrini (Ov) infection is a major public health concern in the Greater Mekong Subregion, with cats as key reservoir hosts. Although machine learning (ML) is widely used in human medicine, its application in veterinary epidemiology remains limited. This study aimed to develop interpretable ML models to predict Ov infection and to identify key risk factors in cats using data from 175 households in endemic areas.

Gut nematode worms are important parasites of people and other animals. The parasitic nematode infects an estimated 600 million people worldwide and is one of the soil-transmitted helminthiases, a WHO-defined neglected tropical disease. It has long been suggested that human infection may be a zoonosis from dogs.

However, it remains a public health concern, particularly in focal areas, especially along the border regions where migration between Thailand and neighboring endemic countries is frequent. Spatial distribution analysis provides a useful method for identifying high-risk areas and implementing targeted integrated control measures.

Herein we generate and screen an Opisthorchis viverrini recombinant secreted proteome to identity antibody biomarkers of liver fluke infection and CCA with sera from study participants in endemic populations and evaluate their utility as point-of-care immunochromatographic tests (PoC-ICTs). We incorporate two of the most promising antigens from the proteome array screen, P1 and P9, into PoC-ICTs to further validate their diagnostic performance.

This study searched the Web of Science, PubMed, Scopus and JSTOR databases for publications on the prevalence of parasitic coinfection in people living with viruses from 1 January 2005 to 30 April 2022, and 356 studies were included and systematically reviewed. A meta-analysis was performed to assess the global prevalence of and factors potentially associated with parasitic infection (helminths and protozoa) in virus-infected people, and the infection burden was estimated.

Traditional control efforts often fail due to complex socio-cultural and ecological factors. The Lawa model, implemented in the Lawa Lake region of Khon Kaen, Thailand, adopts a One Health framework to integrate human health interventions, environmental modifications, and animal reservoir management, addressing the transmission cycle comprehensively.

In Northeast Thailand, its prevalence overlaps with the endemicity of Opisthorchis viverrini, (OV). This study aimed to investigate the prevalence and risk factors of leptospirosis in cats and its association with opisthorchiasis in endemic area of Thailand.

Estimates of national burdens of the foodborne disease (FBD) inform country-level food safety policies, ranking infectious and non-infectious FBD hazards in terms of health and socioeconomic impact to mitigate FBD burdens. Using relevant publications on FBD burdens from scientific literature, this review contends that four major imperatives (health, economic, planetary boundaries, governance) argue for a sustainable programme to quantify national FBD burdens. FBD disproportionately affects children under five years of age, and low- and middle-income countries.

Using an EcoHealth/One Health approach at Lawa Lake in Thailand, our integrated control program achieved a substantial reduction in liver fluke prevalence from 60 % to <5 % over 15 years. Key interventions included chemotherapy, collaboratively designed health education, ecosystem modification, and community participation.

Together, these parasites infect over 14 million people, with an estimated 300 million at risk. Their transmission cycles involve Bithynia snails and Cyprinidae fish as first and second intermediate hosts, respectively, with humans and other fish-eating mammals serving as definitive hosts.

This study examines the factors influencing Opisthorchis viverrini and cholangiocarcinoma prevention within the One Health framework in Kanthararom District, Sisaket Province, Thailand.
Methods: A cross-sectional study was conducted among 327 residents aged 20 and above, utilising a structured questionnaire to assess knowledge, attitudes, perceived self-efficacy and prevention behaviours.
Background: Epidemiologically important food-borne trematodes Opisthorchis viverrini and Clonorchis sinensis are recognized as biological carcinogens of Group 1A, while Opisthorchis felineus is in Group 3 as noncarcinogenic to humans. Mechanisms of the biological carcinogenesis are still elusive. Some studies highlight chronic inflammation as a key factor and common pathway for cancer initiation and progression.

Background: Opisthorchis viverrini (OV) and soil-transmitted helminths (STH) are two of the most common helminths contributing to the Neglected Tropical Disease (NTDs) burden in the Lower Mekong Basin. Although mass drug administration is the cornerstone of control programs to reduce morbidity caused by these infections, this approach has limitations in preventing re-infections. Elimination requires additional measures such as reservoir host treatment, improved hygiene and health education to reinforce MDA's impact.

Despite the reporting of the prevalence of these human liver flukes in the region over the past decades, there has been a lack of a comprehensive and systematic consolidation of this data. Therefore, we aimed to conduct a thorough systematic review and meta-analysis to synthesize and analyze time-trend prevalence estimates of both O.
