The World Health Organization has confirmed that the death rate associated with the current Ebola outbreak in the Democratic Republic of the Congo is estimated to lie between 30% and 50%, a figure that officials have described as deeply alarming. The revised estimate, which is based on confirmed cases, was communicated by Anaïs Legand of the WHO's high threat pathogens team, who noted that the true scale of the epidemic may be considerably larger than recorded figures suggest, given that the virus is believed to have circulated undetected for some time prior to the outbreak being formally declared on 15 May.

As of this week, the WHO has recorded 10 confirmed and 223 suspected deaths among more than 1,000 confirmed and suspected cases. One patient has, however, been discharged following two negative tests — the first confirmed recovery of the outbreak — a development that has been cautiously welcomed by health officials. The organisation's director general, Tedros Adhanom Ghebreyesus, arrived in the Congolese capital Kinshasa on Thursday and was expected to travel to the affected north-east Ituri province, though that visit was delayed by a day.

Efforts to contain the disease are being significantly complicated by the region's ongoing armed conflict. The outbreak is centred on a mineral-rich area in which multiple armed groups operate, including the Rwanda-backed M23 movement, which controls substantial territory in neighbouring provinces. Tedros made a direct appeal to all warring parties to declare a ceasefire, arguing that no political grievance could justify the preventable deaths of civilians. The UN refugee agency has reported that more than 245,000 people have fled eastern DRC to neighbouring countries since January 2025 alone, a displacement crisis that is widely seen as having worsened the conditions for disease transmission.

The Bundibugyo strain of Ebola, which is responsible for the current outbreak, has no approved treatment, a factor that further complicates the medical response. There is no approved vaccine either, though experimental interventions are reportedly being considered. The DRC has now experienced 17 recorded Ebola epidemics since the disease was first identified there in 1976, and the WHO notes that the average fatality rate across all outbreaks has historically stood at approximately 50%. The organisation has reiterated its opposition to travel bans, on the grounds that such measures tend to impede humanitarian access without meaningfully slowing transmission.
