What strain of Ebola is the 2026 DRC outbreak?

Bundibugyo virus (BDBV), one of six known species in the genus Ebolavirus. The 2026 DRC cluster is the third recognised Bundibugyo outbreak in history, after Uganda 2007 and DRC 2012.

Is there a vaccine for Bundibugyo Ebola?

No. The licensed Ebola vaccine Ervebo and the licensed monoclonal antibody therapies Inmazeb and Ebanga are specific to Zaire ebolavirus and do not have demonstrated efficacy against Bundibugyo virus in humans.

What is the case fatality rate for Bundibugyo?

Approximately 25 to 40 percent historically — lower than the typical 40 to 90 percent of Zaire ebolavirus, but still extraordinarily lethal.

Should travellers to East Africa change plans?

WHO has not recommended travel or trade restrictions. For most leisure and business travellers to East Africa, the practical Ebola risk in 2026 remains functionally zero. Healthcare workers travelling for clinical work face different risk and should pre-deploy with formal PPE training.

Public Health Emergency of International Concern — the WHO's highest-level alert mechanism under the International Health Regulations. It triggers obligations on member states to coordinate and share data and justifies an enhanced WHO response posture.
