The context
Why “2026 Ebola outbreak” is everywhere right now
On 16 May 2026, the World Health Organization escalated the ongoing Ebola crisis in Central Africa to a Public Health Emergency of International Concern (PHEIC), the highest alarm level in global health. That declaration is what pushed this story from regional news to global trending status overnight.
The outbreak is concentrated in the Democratic Republic of the Congo, primarily in Ituri province, but it has crossed into Uganda, which has confirmed cases including some involving the Bundibugyo strain of the virus.
August 18 update: 5,021 confirmed cases, 2,378 deaths, now the 2nd-largest Ebola outbreak ever. As of 18 August 2026, WHO reports 5,021 confirmed cases and 2,378 deaths across five DRC provinces. The week ending 9 August was the single worst week in the outbreak’s history, with 579 new confirmed cases and 304 deaths. The death toll surpassed 2,000 on 9 August, 86 days after the outbreak was declared. At this scale, the 2026 DRC outbreak has overtaken the 2018–2020 DRC epidemic (3,317 confirmed) to become the second-largest Ebola outbreak ever, behind only the 2014–2016 West Africa epidemic (28,600+ cases). Uganda’s linked outbreak was declared over on 28 July 2026, after 20 confirmed cases, 18 recoveries, and 2 deaths. The DRC outbreak continues with no approved treatment or vaccine for the Bundibugyo strain. The WHO continues to flag that roughly 80% of new cases arise from unknown transmission chains. Sources: WHO, ECDC, Al Jazeera, MapPR (18 Aug 2026).
Late July 2026 context. The NEJM published a comprehensive clinical review of the Bundibugyo orthoebolavirus strain in July 2026, highlighting the particular difficulty of distinguishing it from other febrile illnesses in resource-limited settings. The case fatality rate among confirmed cases is now approximately 46%.
A PHEIC declaration does not mean a pandemic is imminent, it is a formal mechanism to mobilise international resources, coordinate response, and accelerate access to vaccines and treatments. The WHO and affected national ministries are the authoritative sources for current case counts and official guidance.
