"The current Ebola crisis has taken a terrific toll in West Africa, stressing budgets, stretching fragile health systems to the breaking point and leaving more than 8,600 people dead since it returned to the region early last year. But seldom noted is the toll Ebola has taken on some of the world’s most endangered creatures — the great apes.
Although this outbreak now shows signs of slowing — thanks to the heroic work of local medical professionals and a large influx of foreign aid and volunteers — the disease has continued to ravage West Africa’s gorilla and chimpanzee communities since at least the early 1990s, the Global Post reports.
As with humans, the disease sporadically flares up in primate communities.
'In the last two decades, Ebola has been responsible for several catastrophic great ape population declines,' writes Ria Ghai of the Jane Goodall Institute of Canada. As an example, Ghai cites an Ivory Coast chimpanzee community reduced by half in an outbreak of Ebola in the Tai Forest that lasted two years.
'When all Ebola mortality is summed together,' according to Ghai, 'an estimated one-third of the world’s gorillas and chimpanzees have been killed by this disease.' "
