Health related interactions among people, animals, and the environment have profound influences on disease risk, transmission, and prediction efforts. There are estimates that 60% and 75% of human infectious diseases and emerging human diseases respectively have their source in animals (whether domestic or wild), ( These are called zoonotic diseases and include rabies, West Nile virus, Rift Valley fever, and brucellosis among others.

While human-animal-environmental interactions have long been recognized as being important, some powerful drivers of change are increasingly causing volatility among people, animal, and environmental linkages. These drivers include climate change, population growth, land use/cover changes, and alterations in disease vector ecology.  SFWS research faculty are investigating these drivers in the hopes of mitigating risk to human health while addressing the ecological issues which are confronting our society.
