In 1994, canine distemper contributed to the deaths of thousands of African lions in the Serengeti, demonstrating how disease can rapidly impact large predators.
Small, isolated wildlife populations are highly vulnerable to infectious disease. With fewer than 80 Javan rhinos concentrated in one geographic area, a contagious pathogen could spread rapidly. Diseases transmitted from livestock or invasive species present additional risk. In small populations, mortality rates of even 20 percent can push numbers below recovery thresholds. Veterinary interventions in dense rainforest terrain are logistically complex and stressful for the animals. Conservation authorities therefore implement buffer zones to limit livestock encroachment near the park. Surveillance programs monitor for abnormal mortality patterns. The species’ low genetic diversity may further reduce immune resilience.

Epidemiological modeling shows that disease outbreaks in small populations can follow exponential curves. Without spatial separation between subpopulations, containment options are limited. Vaccination campaigns are difficult to implement for elusive megafauna. This creates a structural vulnerability absent in larger, dispersed species. The health of domestic animals surrounding Ujung Kulon becomes indirectly linked to rhino survival. Public health and wildlife management intersect in unexpected ways.
On a global scale, the risk highlights how biodiversity loss and emerging diseases can reinforce each other. As habitats shrink, wildlife and livestock interactions intensify. A pathogen that might be survivable in a large population could become terminal in a small one. The Javan rhino therefore exists within a narrow immunological margin. Its survival depends partly on microbial events invisible to the human eye. Extinction, in this case, could begin with a fever.
