There are fewer than 1,100 mountain gorillas left on Earth. Every single gorilla has a medical team watching over it. This is their story.
Before the trekkers arrive, before the permits are checked and the briefings begin, before the forest trail is walked for the first time that morning, there are people already deep in the trees. They are not rangers. They are not guides. They are Gorilla Doctors, the only team on earth providing life-saving veterinary care to wild mountain gorillas, and they were in that forest long before you arrived, and they will be there long after you leave.
They are called Gorilla Doctors, and they are the only organisation on earth providing direct, hands-on veterinary care to wild mountain gorillas. Without them, the hour you spend in the presence of these animals, the encounter that changes people in ways they spend the rest of their lives trying to describe, would be considerably less likely to exist at all.
A Promise Made to Dian Fossey
The story begins with two women and an urgent conversation in 1984. Dian Fossey, who had spent years living among mountain gorillas in Rwanda's Volcanoes National Park, had reached a conclusion that kept her awake at night. She had documented what poaching and human encroachment were doing to the gorilla population, and she knew that injury and disease, snares catching the hands of young animals, and human respiratory illnesses crossing species were quietly accelerating the decline. She needed a veterinarian. Not one who worked in a clinic, but one willing to go into the forest.
She found Ruth Morris Keesling, whose father had founded the Morris Animal Foundation, and told her plainly: "There are only 248 gorillas in the world, and they are all going to die." Keesling made her a promise. Fossey was murdered at her research camp in December 1985, just days before Keesling was due to return to Africa. Keesling kept her promise anyway.
In 1986, the Morris Animal Foundation hired Dr. James Foster, the first Gorilla Doctor, and sent him into the forest.
What Gorilla Doctors Actually Do
Every single day, in five national parks across Uganda, Rwanda, and the Democratic Republic of Congo, a team of Ugandan, Rwandan, and Congolese veterinarians walks into the forest to check on their patients. Not metaphorical patients. Named, known, individually monitored gorillas whose health records go back decades.
The veterinarians observe everything: body condition, skin, hair quality, breathing, behaviour, social interaction, appetite. They note changes so subtle that an untrained eye would miss them entirely. When a gorilla can be expected to recover on its own, they let nature do the healing. But when the threat is human-induced, a snare embedded in a wrist, a respiratory infection caught from a tourist or ranger, a wound that has become septic, they intervene.
And intervening on a wild gorilla is not a straightforward procedure. Imagine approaching a 200-kilogram silverback who has never consented to medical care, who does not understand the difference between a syringe and a threat, and who is surrounded by a family he will protect without hesitation. The veterinarians approach gradually, read the group's mood, and work as a team: one managing anaesthesia, one collecting samples, one monitoring the patient's breathing throughout. When a young gorilla once had a snare removed from its leg in Mgahinga Gorilla National Park, the silverback watched every moment and did not move. Somehow, across the barrier of species and language and evolutionary distance, something like trust had been established.
One veterinarian described a moment after treating a gorilla's injured hand: when she returned to the group for a follow-up visit, the silverback extended the once-wounded hand toward her. Just held it out. As if to say: it is better now. Thank you.
The Gorilla You Meet Was Protected Long Before You Arrived
When a GoExplore Safaris guest stands in the presence of a mountain gorilla family, what they are witnessing is not simply nature in an undisturbed state. It is nature in a carefully, quietly protected state, the result of forty years of veterinary dedication, conservation science, and a team of people who have chosen to spend their careers in wet forest at altitude, treating patients who cannot consent, advocate for themselves, or say thank you.
The 800-plus gorillas currently under Gorilla Doctors' daily monitoring represent a conservation miracle. When Dian Fossey told Ruth Keesling that 248 gorillas remained and they were all going to die, she was not being dramatic. She was being accurate. Today, mountain gorillas are the only great ape species on earth whose wild population is growing. They have been reclassified from critically endangered to endangered, a distinction that sounds modest until you understand how rarely a species travels in that direction. Veterinary intervention is estimated to account for half of that population increase.
One Health: The Gorillas Are a Mirror
Gorilla Doctors operate on a principle they call One Health: the understanding that the wellbeing of gorillas, the communities living beside their forests, and the broader ecosystem are not separate concerns but one interconnected reality.
Because gorillas share approximately 98% of human DNA, they are susceptible to many of the same infectious diseases. A common cold carried into the forest by a tracker or tourist can kill a gorilla. This is why the ten-metre distance rule during gorilla trekking exists not as bureaucratic caution but as a genuine medical boundary. It is also why Gorilla Doctors run health programmes for the people living near the parks, vaccinating dogs and cats against rabies, providing health screenings for conservation workers and their families, and monitoring livestock for diseases that could cross into the forest. The gorilla's health and the community's health are the same project.
This understanding that conservation is not a separate conversation from human welfare is one of the most important ideas in modern wildlife protection, and Gorilla Doctors have been living it since before it had a name.
What Your Permit Actually Pays For
When a GoExplore Safaris guest purchases a gorilla trekking permit, the conversation tends to focus, understandably, on what will happen in that hour in the forest. What is less visible but equally real is what the permit funds in the days, months, and years before and after that hour.
A portion of every permit goes directly toward the conservation infrastructure that makes the encounter possible: the rangers who track the gorilla families daily, the anti-poaching operations that protect the park's boundaries, the community programmes that give the people living beside the forest a reason to protect rather than encroach upon it, and the veterinary system that ensures that when something goes wrong inside the trees, someone trained and equipped is already on the way.
You are not simply buying an hour with a gorilla. You are contributing to the only reason that the gorilla is still there.
The Story Continues
Gorilla Doctors are currently monitoring close to 800 habituated mountain and Grauer's gorillas. Grauer's gorillas, also known as eastern lowland gorillas, found only in the Democratic Republic of Congo, are critically endangered and declining, facing pressures that the mountain gorilla story has taught us are reversible, but only with sustained, expert intervention.
Map of 5 National Parks Where Gorilla Doctors Work
The work is not finished. The forest is not safe yet. And every morning, before the trekkers set out and the permits are checked, a team of doctors is already walking in.
At GoExplore Safaris, we believe that understanding what protects a place deepens what it means to visit it. Every journey we design to Bwindi Impenetrable Forest, Mgahinga Gorilla National Park, or Rwanda's Volcanoes National Park carries this context with it. If the gorillas have moved you, the people keeping them alive are worth knowing.
Our Primate Journeys have introduced countless guests to the extraordinary world of mountain gorillas—and the dedicated Gorilla Doctors who help protect them. Discover more about Gorilla Doctors and their vital conservation work.
