A mysterious anthrax outbreak has killed hippos in the Democratic Republic of Congo, raising concerns about potential human transmission.

What it means

An outbreak of anthrax — a bacterial disease caused by Bacillus anthracis — is killing hippos in the Democratic Republic of Congo, with the "mysterious" framing reflecting a sudden, unexplained die-off. Because anthrax spores persist in carcasses and soil, and people in the region often handle or consume meat from dead animals, the outbreak raises concern about spillover into humans.

Accuracy & sourcesSourced

This is a Nature news article (DOI 10.1038/d41586-026-03580-4), not peer-reviewed research; although tagged as a primary source, it is a secondary report of an event that presumably originates with DRC veterinary or health authorities. The occurrence of a hippo die-off is broadly solid, but the anthrax diagnosis and any human-risk assessment depend on field and laboratory data we cannot see from the headline alone.
