The World Health Organization said an Ebola outbreak in the Democratic Republic of Congo is significantly larger than official government figures suggest.

This discrepancy indicates that current containment and care measures are insufficient to stop the virus from spreading through the population. If the actual number of cases remains hidden, health officials cannot accurately allocate resources, or identify new infection clusters.

World Health Organization Director-General Tedros Adhanom Ghebreyesus visited the Bunia region in northern Democratic Republic of Congo on May 30, 2026 [2]. During his visit, Ghebreyesus said he was concerned over the scale of the crisis.

"I am concerned about the size and speed of the Ebola outbreak in the Democratic Republic of Congo," Ghebreyesus said [2].

The WHO said that the actual size of the outbreak could be four times larger than the official numbers [3]. This gap creates "blind spots" that hinder the ability of medical teams to track the virus [1].

Médecins Sans Frontières, also known as Doctors Without Borders, issued a warning on May 29, 2026, regarding the speed of the transmission [2]. The organization said the virus is spreading at a pace that outstrips current efforts to contain it [2].

The surge in cases in the north of the country has led to urgent calls for expanded containment measures. Health organizations are pushing for more comprehensive care, and surveillance to prevent the outbreak from expanding into neighboring regions [1].

Officials are now working to reconcile the official data with the findings from field teams to establish a more accurate baseline for the emergency response [3].

“"I am concerned about the size and speed of the Ebola outbreak in the Democratic Republic of Congo,"”

The gap between official reports and WHO estimates suggests a failure in local surveillance or a reluctance by authorities to report the full scale of the crisis. When infection rates are underestimated by a factor of four, the resulting shortage of beds, vaccines, and personnel can allow a localized outbreak to evolve into a regional epidemic.
