The World Health Organization says containing the fast-moving Ebola outbreak in the Democratic Republic of Congo remains achievable within the next three months — but only on one non-negotiable condition: sufficient funding, medical staff and field capacity actually materialise. The warning comes as the outbreak spreads into a sixth province and climbs to become the second-deadliest Ebola outbreak on record.
Thierno Balde, the WHO’s incident manager for the response, told a video press briefing from Bunia in eastern DRC that response teams can still break the chains of transmission if they get the resources they need, even as case numbers and deaths keep climbing week after week. “If the necessary resources are available, controlling the outbreak is possible,” Balde said, adding that the field response is expanding, but that in several areas the virus is still spreading faster than containment efforts can keep up. It’s a line that captures the paradox at the heart of this response: the science of stopping Ebola is well understood — what’s in question is whether it can be applied fast enough.
More Than 5,000 Confirmed Cases
The WHO’s latest weekly bulletin, based on data through August 16, puts the confirmed case count at 5,021, including 2,378 deaths, spread across 55 health zones in six provinces. Earlier government figures had put the death toll at roughly 2,325 — a gap that reflects differences in the timing of data collection and case reclassification rather than any real disagreement about the scale of the crisis, which is typical in outbreaks of this size and complexity.
With that toll, the current outbreak has become the deadliest in DRC’s history, surpassing the 2018-2020 outbreak that killed roughly 2,300 people. It now ranks as the second-deadliest Ebola outbreak worldwide, behind only the 2014-2016 West Africa epidemic — an event still seared into the memory of public health workers as a turning point in how the world responds to Ebola. The crude fatality rate among confirmed cases has climbed to 47.4%, up from 45.9% just a week earlier, a figure that speaks plainly to both the severity of the outbreak and how many patients are struggling to reach medical care in time.
A Sixth Province Enters the Outbreak Zone
The outbreak has now spread into Bas-Uélé province in the northeast, after a new case was confirmed there, bringing the number of affected provinces to six. The WHO recorded 640 additional confirmed cases and 367 deaths in a single week — numbers that reflect ongoing widescale transmission, particularly in the east, where population movement, trade and mining activity overlap with armed conflict and an already fragile health system now straining under the added weight of the outbreak.
This is DRC’s seventeenth Ebola outbreak since the virus was first identified in 1976 — a fact that underscores a harsh irony: a country that knows this disease intimately is nonetheless facing one of its most violent outbreaks ever. Authorities officially declared the current outbreak on May 15, after an unexplained illness with a high fatality rate was detected in Ituri province, before laboratory tests confirmed the cause as Bundibugyo virus, one of the rarer species that causes Ebola disease. But the outbreak most likely began weeks before it was formally identified — a lag that gave the virus valuable time to spread through communities that are already difficult to reach.
Infections With No Known Source
One of the most serious obstacles facing response teams is that between 70 and 80 percent of new infections cannot be linked to a known chain of transmission, according to health response officials. In practical terms, that means contact-tracing teams still can’t pinpoint the source of most cases, and people carrying the virus may be moving through communities before they’re identified and isolated — which is precisely what makes this outbreak so hard to chase: teams are following the virus rather than getting ahead of it.
Response teams are also grappling with delays in case reporting, growing fatigue among epidemiological surveillance staff after months of sustained work, and difficulty reaching some areas due to armed group activity, deteriorating roads, and heavy cross-border population movement. Compounding the challenge is the absence of a licensed vaccine or approved specific treatment for Bundibugyo virus, unlike the Zaire strain, for which vaccines and antibody treatments already exist. As a result, the current response relies mainly on older, more traditional tools: early detection, isolating patients, 21-day contact tracing, safe burials, and intensive supportive care.
A Funding Gap Threatens the Response
The WHO has so far raised only about 60 percent of the $115 million it needs for its response plan, leaving a funding gap of nearly $46 million. The organisation has warned that the shortfall could delay the deployment of additional teams, the expansion of laboratories, the supply of protective equipment, the establishment of treatment centres, and access to remote areas — which is less an abstract budgetary concern than a direct logistical one: every delayed dollar buys the virus more time.
In an effort to keep pace with the rapid rise in patient numbers, roughly 400 additional beds were added to treatment centre capacity over the past two weeks, while the organisation prepares to deploy more epidemiologists to expand case-finding and contact-tracing operations.
Amid the heavy numbers and mounting warnings, the WHO is holding on to a narrow but genuine window of hope: the scientific knowledge needed to stop Ebola exists and has been proven before. But its success doesn’t rest on science alone — it depends on how quickly patients can be reached, how much trust local communities place in response teams, whether field workers can keep going despite exhaustion, and whether the resources arrive before the virus once again gets ahead of the response.
