Mountain Gorilla Disease Vulnerability and Welfare

Mountain gorillas share 98.3% of human DNA, making them highly susceptible to human respiratory diseases that can devastate small remaining populations.

Key Facts

Approximately 1,063 mountain gorillas remain in the Virunga Massif and Bwindi Impenetrable Forest — the only wild population
Mountain gorillas are the only great ape population that is growing — due to intensive conservation but the number remains critically low
Human respiratory viruses including the common cold can cause severe and fatal illness in gorillas with no prior immunity
Research tourism is a critical conservation funding source but requires strict 7-metre distance rules, mask wearing and sick-tourist exclusion
Ebola virus has killed an estimated one third of all western lowland gorillas in the past 20 years — devastating welfare and conservation simultaneously
Veterinary interventions for injured or sick mountain gorillas by Gorilla Doctors have saved over 60 lives since the programme began

Welfare Considerations

Mountain gorilla welfare is acutely vulnerable to human disease transmission. A simple cold virus can become a community-level respiratory crisis in a gorilla family. Every tourist visit therefore represents a welfare risk that must be managed through strict protocols. The growth of the population to over 1,000 individuals is a genuine conservation success story, but the small size means that individual welfare outcomes have population-level significance. Each gorilla saved by the Gorilla Doctors programme represents both individual welfare improvement and a measurable contribution to species survival. Supporting organisations that fund both veterinary care and habitat protection addresses gorilla welfare at every level.

What You Can Do

Support Gorilla Doctors and the Dian Fossey Gorilla Fund which provide direct welfare interventions for mountain gorillas
If visiting gorilla habitat, strictly observe all distance, mask and health protocols — never visit when unwell
Oppose any relaxation of tourist health protocols that prioritises revenue over gorilla disease risk
Advocate for sustainable funding for mountain gorilla conservation that reduces dependence on variable tourism revenue
Learn about mountain gorilla social structure and individual personalities through published research and share this knowledge widely
