NewsThe Ebola outbreak in the Democratic Republic of the Congo may finally be losing steam, with WHO reporting a modest dip in new cases — but experts say it's far too early to celebrate. With 7,733 cases and 3,732 deaths as of Sept. 20, this outbreak has already surpassed every prior Ebola event in its first 100 days. No licensed vaccines or treatments exist for the rare Bundibugyo strain driving it, though multiple trials are now underway.
The DRC's Ebola outbreak — the deadliest and fastest-spreading on record — is showing tentative signs of slowing, but global health leaders are urging restraint in optimism. WHO Director-General Tedros Adhanom Ghebreyesus noted "encouraging signs" of declining transmission in Ituri province, where the outbreak originated, but a 72.7% surge in cases in North Kivu is offsetting that progress. As of Sept. 20, the outbreak has claimed 3,732 lives from 7,733 confirmed cases.
The scale of this outbreak is historically staggering. In its first 100 days alone, it recorded 5,458 cases — seven times more than the 2014–2016 West African epidemic at the same stage — and has already surpassed the total case and death counts of the second-largest Ebola outbreak ever (2018–2020 DRC). The culprit is the rare Bundibugyo strain, for which no licensed vaccines or treatments exist.
By the Numbers:
Why it matters: With no approved tools specific to Bundibugyo, the response is racing on multiple fronts — deploying an off-label vaccine (Ervebo), running treatment trials, and developing new mRNA and viral-vector vaccines. Preliminary trial data are expected within weeks, and WHO says it's already planning to scale up access if any prove effective.
