  Purpose: Toconduct baseline seroprevalence surveys of pig key zoonoses and evaluate public health risks of pig-raising & pork consumption in one upland and one lowland province in Lao PDR Background: - Smallholder pigs owned by 50-70% of village HH. - No prior epidemiological prevalence surveys and risk analysis. Some indicative district research findings though not comparing ecological context. - Regional increase in zoonoses and increasing disease outbreaks compound health and production risks. Whole of family risk exposure.

  What is theprevalence, social and ecological interactions of these pig related diseases in upland and lowland context? What are the important pig related zoonotic and production diseases in Lao PDR? What is the possible ecological association of these diseases in different pig production systems? How can priorities of trans-disciplinary researchers, decision makers and communities be combined in Lao PDR? What are appropriate recommendations for intervention based on the research results? Ecohealth - multidisciplinary, village ecosystem integration
