ONE WORLD – ONE HEALTHInterface between human-, animal- and global health NOVA Annual Seminar 2011 , Aarhus, Yngvild Wasteson and Halvor Hektoen
One World – One Health Strategic framework to reducethe risk ofEmergingInfectiousDiseases (EID) in theinterface between wild and domesticanimals, the human population and theecosystem. (FAO, WHO, OIE, UNICEF, World Bank, 2008)
Principlesof One world – One health • A holisticapproach to thepreventionofepidemic/enzooticdiseases, • whilemaintainingtheintegretyoftheecosystem, • for thebenefitofmindkind, domesticanimals and biodiversity • A commonunderstandingthatwe all are in he same bathtub
Content • Zoonoses and Emerginginfectiousdiseases EID • Challenges controlling EID • Climatechange and EID • Interdisciplinaryeducation- and research programmes?
Ebola / Marburg Chernobyl Japan 2011 HIV/AIDS Plague Meningitis vCJD Nipah Anthrax SARS Polonium-210 H1N1Pandemic Avian Influenza Chemical spill Melamine Cholera
Link between animal diseases and public health • Zoonoses – infectiousdiseasestransmitted from animals to humans • Alsohealthyanimalsmaytransmitdiseases to humans • 60% ofknown human infectiousdiseases have theirsource in animals (wild or domestic) • 70% ofemerging/reemerging human diseases have theirorigin from animals • 80% ofthepathogenesthatcanpotentially be used in bioterrorism

Rising temperatures - the most certain impact from climate change Intergovernmental Panel on Climate Change - IPCC 2007
Climate change impacts on food prices • Rising food prices push millions back into poverty and malnutrition • Changes in quality, variety, frequency, safety and quantity of food consumed IPCC, 2007
Climate change impacts on water safety • Water stress is projected to affect between 16 and 44 million additional people by 2080 • Reduced summer water by up to 80% with increased potential for contamination, (IPCC 2007) • This may worsen access to safe water and sanitation, which is already unequal in Europe • Increased temperatures and flooding increases the risk of waterborne infections • Water stress also affects food production and nutritional levels
Climate change impacts on food security and nutrition • All 4 dimensions of food security affected: availability, stability, access, utilization • Thus negative impacts on quality, variety, frequency, safety and quantity of food, and thereby negative impacts on health • Increases malnutrition • In seasonally dry and tropical regions, even slight warming (1-2ºC) reduces yields In developing countries, agricultural output is expected to decline 10-20% by 2080
Climate change can increase the risks of foodborne disease • Pollution of water, air, soil, feed • Pathogens • Algal toxins • Toxic chemicals • Heavy metals • Persistent organic pollutants • Food production • Microbiological contamination • Survival and growth of pathogens • Contaminated water for irrigation and food processing • Increased use of fertilizers, pesticides and antibiotics • Demographics and human behavior • Increased opportunities for food contamination
Climate change impacts on vector-borne diseases • Climate change will challenge the progress made towards eliminating malaria in Europe and central Asia and increase the risk of local outbreaks (WHO 2004) • Lyme disease is shifting to higher latitudes and altitudes, following movement of ticks (WHO 2005) • Leishmaniasis, a skin disease transmitted by sand flies, is travelling north (WHO 2005) • In the 2007 Chikungunya outbreak in Italy the presence of a suitable vector allowed sustained local transmission (ECDC 2007)

Climate change will affect, in profoundly adverse ways, some of the most fundamental determinants of health: food, air, water. Margaret Chan, Director General, WHO
What’s in it for us (thisaudience)? • Need for knowledge and an interdisciplinary, cross sectoralapproach to thesurveillance, control, prevention and mitigationof EID • Interdisciplinary (inter Nordic?) education- and research programmes
Coordinationof public and veterinary health Improvementofbiosecuritymeasures • Sanitaryconditions • Sustainablefarming systems • Land- and water resources • From Farm to Fork approach • Economicalconditionsofcountries and communities • Preservingtheenvironment and biodiversity
