DR Congo: Ebola cases surpass 4,000 since current outbreak

Democratic Republic of Congo’s confirmed Ebola cases have surpassed 4,000 for the first time in the current outbreak, with government data placing the total at 4,053 infections, including 1,850 deaths.

Cases have been recorded across five provinces: Ituri, North Kivu, South Kivu, Haut-Uele and Tshopo.

The outbreak, caused by the Bundibugyo strain rather than the more familiar Zaire strain, has been described as the fastest-spreading Ebola outbreak on record and now ranks as the world’s second-largest.

Experts believe the virus was circulating for months before the outbreak was formally declared on May 15, 2026, meaning the true case count could be significantly higher than official figures suggest.

A study published in the journal Science last month concluded the outbreak likely began in January, or possibly earlier, in Ituri province, with researchers identifying more than 500 suspected cases between mid-January and the May declaration.

This delayed detection has been a major factor in how far the disease has spread before containment efforts could catch up.

Several compounding factors have allowed the disease to outrun containment: delayed detection, overwhelmed surveillance systems, ongoing military conflict in the region, and a lack of vaccines and treatments specifically suited to this viral species.

Because existing Ebola vaccines and therapeutics were developed for the Zaire ebolavirus species, their effectiveness against the Bundibugyo strain circulating in this outbreak is less certain, prompting the WHO to push for expanded vaccine trials.

For context on scale, only the West African outbreak of 2014-16 has been larger, having infected more than 28,000 people across Guinea, Liberia and Sierra Leone.
