A fresh anthrax flare‑up in the war‑torn Virunga National Park has left 28 hippos dead and raised alarms for nearby communities.
Key points
- Anthrax spores can persist in soil for decades, resurfacing during dry periods when herbivores graze close to the ground.
- The death of 28 hippos represents a significant blow to a population of roughly 2,700, undermining years of conservation effort.
- Human communities near the outbreak face zoonotic risk, especially where food insecurity drives bushmeat consumption.
- Ongoing armed conflict restricts ranger patrols and hampers timely disease containment in Virunga.
Virunga National Park in eastern Democratic Republic of the Congo is grappling with a new anthrax outbreak that has killed 28 hippopotamuses, according to park officials. The deaths have added to a previous episode last year that claimed 65 hippos in the same protected area.
Anthrax is caused by the spore‑forming bacterium *Bacillus anthracis*, which can survive in soil for decades. During dry spells, herbivores grazing close to the water ingest dormant spores that have settled in dust and mud, a process the park’s ecology and veterinary expert Joël Mbusa Mapoli says is driving the current mortality around the Semuliki River.
Spore‑Driven Threat to Wildlife
Hippos act as ecosystem engineers, moving nutrients between land and water. Mapoli notes that the loss of dozens of individuals “creates a shockwave across the landscape,” threatening the stability of a hippo population estimated at over 2,700 animals in 171 groups.
Anthrax is zoonotic, meaning it can jump from animals to humans. Park management has warned residents near the Semuliki River and Lake Edward that handling carcasses, skinning dead animals, or consuming infected bushmeat puts them at risk, echoing past human cases linked to wildlife spikes in North Kivu.
Ecological Ripple Effects
The outbreak is unfolding against a backdrop of armed conflict. For nearly three decades, fighting between the Congolese army and M23 insurgents has limited ranger access to large parts of the park, hampering surveillance and rapid response. Environmental activist Olivier Ndoole Bahemuke warns that “prolonged insecurity completely shreds the institutional safety nets meant to protect both people and nature.”
Authorities, including the Congolese Institute for the Conservation of Nature and health ministries, are urged to maintain active surveillance, safely dispose of carcasses, and prevent spore spread into soil and water. Experts stress that wildlife health, human health, and political stability are interlinked; neglecting any one factor could collapse the whole system.
Reader questions
How can anthrax spread from hippos to people?
People can become infected by handling dead animals, skinning carcasses, or eating contaminated bushmeat, as the bacterium can enter the body through cuts, inhalation, or ingestion.
What measures are being recommended to control the outbreak?
Local authorities are advised to keep active surveillance around affected rivers, promptly and safely dispose of carcasses, and coordinate health and conservation agencies to limit spore dissemination.
