Disease Investigations

Disease—whether driven by pathogens, pollutants, genetics, or dietary deficiencies—can threaten vulnerable wildlife populations as significantly as do overhunting and habitat destruction. Wildlife diseases may also affect humans, livestock, and the economy. Pinpointing a disease’s origin, how it develops, how it spreads, and how it can be stopped is essential to protecting wildlife and human communities.
On five continents, WCS-Global Health is conducting health monitoring and disease investigations. Their work is incredibly diverse, varying from health studies of gorillas in small pockets of remote jungle to migratory birds that travel across hemispheres. In the past few years, WCS health experts have been pivotal in proving that West Nile virus had spread into the U.S., investigating why thousands of penguins were washing ashore at the southern tip of South America, and examining why amphibians are declining all over the world.
WCS Projects
WCS launched GAINS (the Global Avian Influenza Network for Surveillance)--the only global disease surveillance program that focuses on wildlife populations; all others focus primarily on diseases of humans and domestic livestock.
Throughout Ebola high-risk zones, our researchers assess great ape health and improve Ebola prevention awareness in remote communities.
In the summer of 1999, WCS pathologists were critical to unraveling the mystery surrounding West Nile virus. Their subsequent vaccination work has saved the lives of hundreds of birds within WCS parks as well as in zoos and aquariums throughout the country.

A paper by WCS-Global Health scientists suggests that cancer is a growing threat to wildlife populations, and that environmental pollutants are a major cause.
After nearly dying from eating a poisoned animal carcass, a critically endangered white-rumped vulture was nursed back to health by wildlife veterinarians and conservationists from WCS and Angkor Centre for Conservation of Biodiversity.
