Since the WHO's global health emergency declaration in May, the DRC's Bundibugyo Ebola outbreak has reached 381 confirmed cases and 64 confirmed deaths as of June 3, according to the European Centre for Disease Prevention and Control. Uganda has added 19 confirmed cases and two deaths of its own, with three new Ugandan cases reported on June 5 — all contacts of known confirmed cases.

CDC's Worst-Case Math

On Friday, the U.S. Centers for Disease Control and Prevention published computer modeling showing a grim range: 10,000 cases to more than 20,000 — depending almost entirely on how fast infected people get isolated.

Dr. Satish Pillai, the CDC's incident manager for the Ebola response, said plainly that without strong public health interventions, "the modelling work suggests an outbreak of that scale is possible."

That scale would be near the 2014-2016 West Africa outbreak — the worst in recorded history — which produced more than 28,000 cases and killed over 11,000 people.

Jennifer Nuzzo, director of Brown University's Pandemic Center, urged caution on the specific numbers. "I wouldn't read too much into the specific numbers," she told The Guardian. "It's really hard to make an accurate projection when you have limited data."

But the directional warning is unmistakable.

The Gorilla Problem

Virunga National Park in eastern DRC is home to several hundred mountain gorillas — roughly a third of the entire species' surviving population. The Bundibugyo Ebola virus is deadly to humans. It is catastrophic to great apes.

Emmanuel de Merode, director of Virunga National Park, spoke with NPR on June 3. He has been stationed in eastern DRC since 1993. His assessment: "The situation we're living through now is certainly the worst we've experienced in the past 30 years."

De Merode has witnessed three decades of civil war, multiple Ebola outbreaks, and mass displacement.

De Merode's team of over 800 rangers is now building Ebola screening checkpoints inside the park. Some rangers are specifically assigned to protecting gorillas from exposure. They are doing this with, in de Merode's words, "severely limited resources" — while also coping with an active, violent armed conflict surrounding the park.

There is no licensed vaccine for Bundibugyo Ebola. This strain is different from the Zaire strain that prior vaccines were designed to target. The international community does not have a ready tool for the biological threat these rangers are facing every day.

The Compounding Disaster Context

The International Rescue Committee flagged the DRC in its 2026 Emergency Watchlist — placed among the top ten countries most at risk of humanitarian catastrophe — before Ebola entered the equation.

Nearly 27 million people in DRC face crisis-level food insecurity, according to the IRC. That's roughly a quarter of the country's population. Over 8.2 million children and pregnant women need nutritional assistance right now.

Health infrastructure across conflict-affected North and South Kivu was already gutted. The IRC reports 85% of clinics in those provinces had severe medicine shortages, and nearly 40% had lost critical staff — before this outbreak accelerated. In North Kivu, 70% of health facilities were non-functional by mid-2025.

The IRC also notes that DRC was the African country most affected by USAID funding cuts, and the third-most impacted globally. Security incidents against aid workers rose 33% in the first nine months of 2025 compared to the same period in 2024.

Then Ebola showed up.

What's Getting Overlooked

Most outlets are focused on the headline case counts. Some are correctly contextualizing the CDC modeling, but several critical details are being underplayed.

Experts noted to The Guardian that infections may have been occurring as far back as February — but health officials initially tested for the wrong Ebola strain. That early-response failure deserves scrutiny, and it's barely getting any.

The ECDC data also shows the geographic spread is already significant: Ituri province leads with 359 confirmed cases across 17 health zones, but North Kivu now has 19 cases across seven health zones and South Kivu has three more. Multiple provinces. Multiple health zones. This is not contained.

The armed conflict angle is being treated as background rather than a primary obstacle. Over 120 armed groups operate in eastern DRC according to the IRC. The M23 rebel group — backed by Rwanda — has killed more than 2,100 people since a June 2025 peace agreement that hasn't held. You cannot run an effective outbreak response when your health workers and park rangers are dodging armed militia.

The Broader Risk

If you're not in DRC or Uganda, you're not directly at risk today. But the 2014 outbreak started as a regional problem too.

The CDC's modeling exists for a reason. An outbreak near the scale of 2014 would stress global health response capacity in ways that echo far beyond central Africa.

Back home: U.S. USAID cuts directly degraded the health infrastructure now struggling to contain this virus. That's a direct line from budget decisions made in Washington to body counts in Ituri. Whether those cuts were justified on fiscal grounds is a legitimate debate — but denying the connection is dishonest.

The rangers in Virunga are building checkpoint posts with limited gear, surrounded by rebels, trying to save both humans and the last mountain gorillas on earth from a virus nobody has a vaccine for.
