“…The lack of relation in the present study suggested that additional data on the distribution of ponds and irrigation systems, at finer resolutions, should be considered. High O. viverrini prevalence had been reported in villages located in irrigated areas with more developed irrigation systems and water dependent land use in Khon Kaen province (Sornmani et al, 1981). Indeed, water resource development, particularly the constructions of ponds for freshwater aquaculture and irrigation ditches for rice production, might have converted the northeastern Thailand landscape vulnerable to the parasite (Wang et al, 2011).…”

Environmental determinants of Opisthorchis viverrini prevalence in northeast Thailand

Abstract.Opisthorchis viverrini infection is an important, human, parasitic disease along the middle and lower Mekong River of Southeast Asia. Despite vast efforts in epidemiological research, the wide geographical variation in O. viverrini prevalence remains unexplained. To investigate the potential influence of village location, prevalence data recorded during the year 2009 for 90 villages in northeast Thailand were analysed by a geographical information systems approach based on a digital elevation model for altitude determination. Land use compositions of village surroundings were derived from images produced by the Thematic Mapper of the Landsat satellite and landscape metrics were applied to quantify spatial patterns. Pearson's correlation coefficients were used to evaluate the associations between the environmental factors and O. viverrini prevalence. In spite of no statistical difference (P = 0.117), higher-ground villages generally had a lower level of opisthorchiasis than those situated lower down, while a significant negative correlation was detected between O. viverrini prevalence and the composition of farmland with low water content (P = 0.028), indicating the potential influence of agricultural lands with drought-tolerant crops. Strengthening this hypothesis, a significant positive association with O. viverrini prevalence was found for the combined land use classes of water and of farmland with high water content (P = 0.032), indicating that the dominance of a large land use patch capable of providing suitable habitats for the intermediate hosts might contribute to the disease. This study highlights the influence of landscapes on the epidemiology of O. viverrini infection and emphasises the need to incorporate land use planning into control strategies.

“…Some papers that did not have positive nutrition outcomes mentioned the need for nutrition and/or health education (human capital) to produce the desired nutrition effect 31,35,37 . One investigation assessed differences between agriculture only and agriculture plus nutrition education, and showed a dietary benefit of including nutrition education 13 .…”

Objectives: To review the impact of agriculture interventions on nutritional status in participating households, and to analyse the characteristics of interventions that improved nutrition outcomes. Design: We identified and reviewed reports describing 30 agriculture interventions that measured impact on nutritional status. The interventions reviewed included home gardening, livestock, mixed garden and livestock, cash cropping, and irrigation. We examined the reports for the scientific quality of the research design and treatment of the data. We also assessed whether the projects invested in five types of 'capital' (physical, natural, financial, human and social) as defined in the Sustainable Livelihoods Framework, a conceptual map of major factors that affect people's livelihoods. Results: Most agriculture interventions increased food production, but did not necessarily improve nutrition or health within participating households. Nutrition was improved in 11 of 13 home gardening interventions, and in 11 of 17 other types of intervention. Of the 19 interventions that had a positive effect on nutrition, 14 of them invested in four or five types of capital in addition to the agriculture intervention. Of the nine interventions that had a negative or no effect on nutrition, only one invested in four or five types of capital. Conclusions: Those agriculture interventions that invested broadly in different types of capital were more likely to improve nutrition outcomes. Those projects which invested in human capital (especially nutrition education and consideration of gender issues), and other types of capital, had a greater likelihood of effecting positive nutritional change, but such investment is neither sufficient nor always necessary to effect change.

“…In Thailand, O. viverrini is still most prevalent in the north and northeast where 19.1 and 15.7%, respectively were infected while the prevalence amongst locals in the central and southern districts was 3.8 and 0%, respectively [105]. In some hotspots in Khon Kaen province in northeast Thailand the prevalence amongst villagers reached between 55 and 97% [106,107].…”

The discovery history of opisthorchiid flukes dates back more than 200 years. The life cycle of these liver flukes includes prosobranch snails as the first and a big variety of freshwater fish as the second intermediate hosts. Opisthorchis felineus, O. viverrini and Clonorchis sinensis are species of major medical importance, while sporadic cases of human infection with other representatives of this family are also documented in the literature. There are estimations that 17 million people are infected and more than 350 million people are at risk, mainly in Asian countries. Although opisthorchiid flukes live in the bile ducts of the liver and in the gall bladder, they can affect surrounding liver tissue and even other organs. They are also known to induce the production of autoantibodies as well as allergic reactions. However, the main medical significance is their role in the formation of malignant tumors. Since the clinical symptoms are not specific, a diagnosis must be confirmed by parasitological examination or the detection of antibodies. Apart from coproscopical methods, there are more recent and highly specific assays available, like the detection of coproantigen or the detection of DNA. Praziquantel is the drug of choice for the treatment of opisthorchiidosis. In order to prevent infection, consumption of raw flesh of freshwater fish must be avoided.
