Mountain gorillas are some of man's closest living relatives
They share more than 98% of their DNA with humans.
But that similarity to man now also makes them vulnerable as the region tackles an outbreak of the deadly Ebola virus.
“We are in a very critical time of Ebola. It is one of the diseases we are concerned about that can spread between people and wildlife," says Gladys Kalema-Zikusoka, a veterinary doctor and gorilla conservationist.
Uganda's gorillas have never had Ebola, she says, but other populations in the region have been hit hard by the disease.
