Anthrax outbreak kills dozens of hippos in DR Congo park

An ongoing anthrax outbreak in Virunga National Park has resulted in the deaths of 28 hippopotamuses over the span of a month, drawing concern from communities living near Africa's oldest protected reserve. Residents near the Vitshumbi enclave began noticing dead animals in the Semuliki River during September, prompting laboratory testing that confirmed the presence of the Bacillus anthracis bacterium. This development coincides with the region's broader struggles against an ongoing Ebola outbreak.

Park officials stated that the bacteria can be transmitted to humans through contact with sick or dead animals or by consuming contaminated meat. Consequently, authorities have launched public awareness campaigns advising locals to avoid touching or eating deceased wildlife and to report any carcasses immediately. Park teams are actively monitoring the affected zones, coordinating safe carcass disposal, and tracking new mortality cases.

Experts note that recurring anthrax outbreaks in the ecosystem are often linked to environmental and climatic pressures. When vegetation becomes scarce during dry periods, herbivores tend to congregate near remaining water sources and graze closer to contaminated soil. Joel Mbusa Mapoli, a veterinary and ecology expert, emphasized that the loss of hippos threatens the local ecosystem since these animals act as engineers that regulate nutrient flows between aquatic and terrestrial environments.

Anthrax deaths among hippos in Virunga National Park threaten both regional wildlife and local public health.

Understanding the anthrax disease threat in the park

Compounding the wildlife crisis, armed conflict has persisted in the region for nearly three decades, leading to significant deforestation and poaching while diminishing the park's control over parts of its territory over the past four years. In response to these overlapping challenges, specialists urge a comprehensive approach combining conservation efforts with public health safeguards.

Why it matters

The recurrence of anthrax among vulnerable wildlife populations highlights the severe compounding pressures of environmental stress and armed conflict in eastern DR Congo. This situation threatens key ecological species whose disappearance could severely disrupt local aquatic and terrestrial habitats while posing direct transmission risks to nearby human populations.
