The Democratic Republic of the Congo is battling its worst Ebola outbreak on record — and it's moving at an unprecedented pace. Caused by the Bundibugyo virus (BV), the outbreak has reached 6,757 confirmed cases and 3,267 deaths as of early September 2026, with a case fatality rate of 48.3%. It has spread to 61 health zones across six provinces and crossed into Uganda. The CDC noted the outbreak surpassed 1,000 confirmed cases in just 40 days — compared to roughly 235 days during the 2018 DRC outbreak.

What's fueling the rapid spread? A combination of factors: no licensed BV vaccine or approved treatment, ongoing armed conflict limiting healthcare access, population displacement, food insecurity, and deep public mistrust of health authorities. Over 260 attacks on healthcare workers have been reported in six months, and 43 HCWs have died from the disease.

By the Numbers:

• 6,757 confirmed cases; 3,267 deaths; CFR of 48.3%
• 61 health zones across 6 provinces affected

• 1,000 cases in 40 days (vs. ~235 days in 2018)

• 43 healthcare worker deaths as of August 21, 2026
• $50 million in immediate funding needed, per WHO
• Contact tracing follow-up improved from ~40% to ~80% (target: 95%)

Why it matters: With no approved vaccine or treatment for BV, and containment severely hampered by conflict and mistrust, this outbreak poses a serious humanitarian and global health security risk. Clinicians worldwide — especially in Europe — should remain alert for returning travelers presenting with compatible symptoms.
