Food Security, Public Health and Other Consequences of Animal-borne Illnesses What is “One Health?” Why is it important?

Food Security, Public Health and Other Consequences of Animal-borne Illnesses One Health affects Food Security affects Nutritional Status affects Immunity affects Disease Susceptibility

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Key characteristic – Human Nutrition Goats and chickens are important sources of nutrition

Food Security, Public Health and Other Consequences of Animal-borne Illnesses

Advantage of goats and chickens in food security – No requirement for formal feed inputs Sustainability of goats and chickens in agricultural production – Food – Non-food animal products Fertilizer hair

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Animal and human burden of disease – Avian influenza May cause significant disease if a highly pathogenic variant in both domestic birds and humans Spread by infectious droppings or aerosols – Newcastle disease May cause significant disease in domestic birds, minor disease in humans Spread by infectious aerosols – Brucellosis May have significant disease in humans, may be asymptomatic in goats Spread by contact with infectious material, including milk

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Loss of protein provided goats and chickens – Adults and child development Less wealth accumulation – Loss or reduction in eggs and milk

Food Security, Public Health and Other Consequences of Animal-borne Illnesses The relationship between nutrition and human immune function – Protein – Micronutrients (vitamins and minerals)

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Malnutrition and infectious disease susceptibility and maternal health – Impact on pregnancy, parturition and post- parturition – Impact of low birth weight – Circulation of common childhood and other diseases – Circulation of neglected diseases of the developing world

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Diarrheal disease – Vitamins A, D, B12, folate, copper, iron, manganese, selenium, zinc Lower respiratory infections – Vitamin D, calcium, zinc Measles – Vitamin A TB – Vitamin A, D (malnutrition is a major risk factor for progression) Malaria – Vitamin A, zinc

Food Security, Public Health and Other Consequences of Animal-borne Illnesses Health, nutrition, and economic costs and productivity – Ability to perform work – Costs of medical care – Ability to contribute to the non-farm economy – Ability to provide for family members – DALY and QALY
