Confirmed positives
The analysis of 21 carcasses with suitable tissue determined that 10 gorillas, 3 chimpanzees, and 1 duiker were confirmed carriers of the Ebola virus.
🚀 Welcome to the official Bubu community!
An immersive visual experience exposing the real impact of the Ebola virus on the Gorilla gorilla and its ecosystem between Gabon and the Republic of Congo.
OUR AMBASSADOR
Bubu is the digital face of this initiative. His mission is to highlight the ecological emergency facing mountain gorillas in Central Africa.
“A patient observer with the body of a brachiator and the manual repertoire of a specialist.”
The adult male was seen solving a leathery pod through a coordinated sequence: foot fixation, alternating hand traction, canines as a wedge, and wrist rotation. For the team, that scene changed the scale of the discovery.

The dense high-mountain forest ecosystem is an extremely fragile environment against the spread of human pathogens, severely affecting gorilla populations in key Central African reserves.
Great ape populations, specifically chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla), accounted for 66.3% of the total recorded animal deaths during the outbreak peaks.
The analysis of 21 carcasses with suitable tissue determined that 10 gorillas, 3 chimpanzees, and 1 duiker were confirmed carriers of the Ebola virus.
Epizootic outbreaks in wildlife demonstrably began before each of the five documented human outbreaks.
Taxonomic family of great apes, severely depleted by the virus.
Comprehensive network formed alongside Ministries of Health and wildlife organizations.
High-risk necropsies on these animals required airtight suits with air filtration equipment to prevent new infections among researchers.
“Repeated contacts between young individuals and their mothers are a significant risk factor for transmission.”Rouquet et al., 2005
The high population density of gorillas in this region (up to 10 individuals/km²) could have facilitated and amplified the rapid spread of the epizootic.
Although the virus jumps from a natural host, group cohesion and troop interaction (fights, social grooming) exacerbated contagion among individuals.
If the dominant silverback male is affected and dies quickly, possibly infected females are forced to integrate into another group.
Investigations showed that every single initial human infection came from a specific point in the jungle.
All human outbreaks (2001-2003) in the area stemmed directly from the handling or hunting of infected wild animal carcasses.
Two clear peaks in ape mortality were recorded: Ekata (Nov-Dec 2001) and Lossi Gorilla Sanctuary (Dec 2002 - Feb 2003).
It became essential to educate local populations about the extremely high risk of interacting with animal carcasses or using their meat.
Health data was centralized in the Viral Hemorrhagic Fever Committee (VHFC) with support from CIRMF for reliable diagnostics.
Organizations already working there (ECOFAC, WCS, WWF) used GPS trackers to locate and report findings.
The network managed to detect infected carcasses in Kéllé almost three weeks before the epidemic broke out in the human population.
Inaccessible roads required light aircraft flights and maximum security laboratories operating remotely.

Editorial transparency: Simia bubuensis and the specimen “Bubu” are maintained in this document as a creative narrative framework. However, the mortality data on Gorilla gorilla presented comes entirely from verified scientific literature on the Ebola crisis (2001-2003).
