The Ebola Outbreak in Congo Is Now the Deadliest the Country Has Ever Seen
The Ebola outbreak in the Democratic Republic of the Congo has become the deadliest in the country's history, with at least 2,325 deaths recorded, according to DRC government data reported on 17 August 2026 The Guardian. The toll surpasses the previous DRC outbreak that ran from 2018 to 2020. Confirmed cases have climbed to 4,945, including 101 detected in the 24 hours before the report.
The World Health Organization has said the outbreak is on track to surpass the 2014–16 west Africa epidemic as the biggest ever. That earlier outbreak resulted in 28,616 cases and 11,310 deaths across Guinea, Liberia, and Sierra Leone. The speed of the current DRC surge is a particular concern. The 2014–16 outbreak took nearly five months to reach 1,000 deaths. The DRC outbreak passed 2,000 deaths in under three months. The United Nations warned on Friday that "Ebola is winning in the Democratic Republic of the Congo," noting that the epidemic was killing one person every 30 minutes.
Six of the DRC's 26 provinces have been affected, mostly along the country's north-eastern border. More than 3,400 of the confirmed cases have been recorded in Ituri province, where the outbreak was first reported. Uganda has reported at least 20 cases, all in the capital Kampala, with the last case reported on 21 June and no signs of the virus spreading within the community.
The outbreak is caused by the Bundibugyo strain of the Ebola virus. A "strain" is a version of a virus with its own distinct characteristics, much like different varieties of the flu. No approved vaccines or treatments exist for the Bundibugyo strain. WHO Director General Tedros Adhanom Ghebreyesus said two vaccines developed specifically for this strain were being tested on people. Clinical trials of two possible treatments began in Ituri in July 2026.
The WHO declared the outbreak in the DRC and Uganda a public health emergency of international concern in May 2026. This is the WHO's highest alert level, meant to signal that a health crisis could cross borders and requires a coordinated global response. WHO genetic analysis shows the virus had started spreading in February 2026, months earlier than the declaration. A newly declared Ebola cluster in the DRC recorded 101 confirmed cases and ten deaths between its declaration on 15 May 2026 and 25 May 2026, kept separate from other confirmed cases. The WHO intensified its response against Ebola in the DRC as of 25 May 2026, according to a UN News report. The WHO has reported that this is the 16th Ebola outbreak in the country since the disease was identified in 1976.
The broader context here is a story of a virus moving faster than the global response. The WHO's own data confirms the outbreak began in February, yet the emergency declaration did not come until May. That three-month gap is the period during which the virus established itself in ways that have now made this the deadliest outbreak in Congolese history. The fact that the death toll surpassed 2,000 in under three months, compared to nearly five months for the west Africa outbreak to reach 1,000, suggests this virus is either spreading more easily or operating in conditions that make it harder to contain — or both.
The Bundibugyo strain adds a serious complication. A vaccine used effectively in earlier DRC outbreaks was designed for a different strain of Ebola, so it does not work here. Two vaccine candidates are now being tested on people, with treatment trials underway in Ituri, but those clinical trials only began in July. They are racing against a virus already killing one person every half hour. With no approved medicine to give patients, frontline responders are relying entirely on basic public health measures: isolating sick people, tracing anyone who had contact with them, and ensuring safe burials.
Looking at what this means for the wider region, the picture in Uganda offers a narrow window of cautious optimism. The 20 reported cases in Kampala, with the last detected on 21 June and no spread within the community, suggest that monitoring at the border has held, at least for now. The emergency declaration in May, though late relative to the February origin, may have helped trigger Uganda's response in time to prevent the virus from taking hold. The DRC's own situation, however, remains the biggest unknown. With six provinces affected and Ituri alone accounting for over 3,400 confirmed cases, the outbreak is concentrated in a border region shaped by long-running violence, people on the move, and health systems that are stretched thin.
