The Democratic Republic of the Congo is experiencing the fastest-growing Ebola outbreak in history, with confirmed cases surpassing 4,000 and over 1,800 deaths as of early August 2026. Health officials fear the Bundibugyo strain may be mutating due to uncontrolled spread, with more than two-thirds of deaths occurring in communities rather than treatment centres, indicating massive gaps in contact tracing. The crisis is being compounded by health worker strikes over unpaid wages and concerns about reduced U.S. funding through USAID.
- The DRC Ebola outbreak has surpassed 4,000 cases and 1,800 deaths, making it the second-largest outbreak ever recorded and the fastest-spreading in history—with 8x more cases than the West Africa outbreak had after 11 weeks.
- Health officials fear the Bundibugyo strain may be mutating due to uncontrolled transmission; 90% of admitted patients in treatment centres have no known epidemiological link, and contact tracing is severely inadequate (10 contacts per case vs. expected 40).
- Health worker strikes over unpaid wages since May are disrupting response capacity at the outbreak epicentre in Ituri province, which accounts for 90% of cases.
- Cuts to U.S. USAID funding have reduced American presence and supply chains in the DRC, further hampering containment efforts according to critics.

Currently, the DRC has the second worst Ebola outbreak in the history of ever, and the virus may be mutating because this epidemic is not controlled—as viruses can reliably be predicted to do. Through USAID, the U.S. used to have a very strong presence in DRC. Trump and Musk killed that.
