The World Health Organization upgraded the public-health risk level for the Bundibugyo strain of Ebola in the Democratic Republic of Congo to "very high" [1].
This escalation signals a critical turning point in the outbreak. The shift from a "high" to a "very high" risk assessment at the national level [2] suggests that current containment efforts are struggling to keep pace with the virus's spread.
WHO Director-General Tedros Adhanom Ghebreyesus announced the change on May 22, 2026 [1]. "The Ebola outbreak in Congo is spreading rapidly and now poses a very high risk at the national level," Tedros said [1].
The outbreak is primarily centered in the Ituri province [3]. However, health officials are now monitoring neighboring Uganda as the virus threatens to cross borders [3]. This geographic expansion complicates the logistics of medical response and surveillance.
Beyond the rural epicentre, the WHO cited evidence of possible urban transmission as a primary driver for the risk upgrade [1]. The movement of infected individuals into densely populated cities could accelerate the transmission rate and overwhelm local healthcare infrastructure.
"We are seeing an increase in cases and the risk is now very high," a WHO spokesperson said [2]. The agency is focusing on expanding surveillance, and increasing the availability of treatments to prevent a wider regional crisis.
International health teams are coordinating with the Congolese government to deploy more resources to the Ituri province. The Bundibugyo strain presents specific challenges for health workers who must manage rapid patient deterioration while preventing further community exposure.
“"The Ebola outbreak in Congo is spreading rapidly and now poses a very high risk at the national level,"”
The transition to a 'very high' risk level indicates that the outbreak is no longer contained within a localized rural area. Urban transmission and cross-border movement into Uganda create a high probability of a regional epidemic, requiring a shift from containment to a larger-scale emergency response to prevent a systemic collapse of health services in the affected provinces.
