"This research proves that hunting and consumption of great apes represent a serious health risk for people in Central Africa, and a risk that can be avoided," said Dr. William Karesh, field veterinarian for the Wildlife Conservation Society and a co-author on the paper. "What we need now is improved awareness of this risk in communities where bushmeat is still a source of sustenance and continued monitoring of wildlife in the region. We have identified a 'win win' opportunity by using this information to both protect endangered apes from illegal hunting and to protect humans from deadly outbreaks."
The paper provides definitive proof for the assumption that Ebola moves from wildlife populations to humans through the consumption or handling of carcasses or bushmeat.
Specifically, the researchers found that Ebola infections in wild animals such as gorillas, chimpanzees, and occasionally duikers (a diminutive antelope species), move across the human-wildlife divide through hunters taking either sick animals or carcasses for meat. Hunters can then spread the disease to families and hospital workers, creating the conditions for an epidemic in the process.
Between August 2001 and June 2003, researchers noted that wildlife outbreaks occurred prior to five human outbreaks in the same relative locations. During this same period, 98 animal carcasses were discovered in the region straddling northeast Gabon and the northwest Republic
