Global Health Groups Battle Congo's Second-Deadliest Ebola Outbreak

In the eastern provinces of the Democratic Republic of Congo, health workers move through clinics and isolation wards treating a virus that has already killed more than 2,500 people. The Bundibugyo strain of Ebola, which emerged in May and triggered a global health emergency declaration, continues its spread despite the world's attention having largely moved elsewhere. Over 5,200 confirmed cases have been documented since the World Health Organization sounded the alarm on May 17, and as of early August, more than 550 people remained isolated with active infection. The fatality rate sits at 44 percent—a grim proportion for a virus with no vaccine yet available.

This is the second-deadliest Ebola outbreak in recorded history, surpassed only by the West African epidemic of 2014 to 2016, which claimed more than 11,300 lives across multiple countries. What makes the current crisis distinct is both its rarity and its geography. The Bundibugyo strain has appeared only three times in central Africa, and this outbreak is unfolding in a region fractured by military conflict. Eastern Congo, where the virus is most concentrated, has become a landscape where armed groups operate with relative impunity, making it extraordinarily difficult for medical teams to reach patients, establish treatment centers, or conduct the systematic surveillance needed to track the disease's movement.

Misinformation compounds the medical challenge. Communities skeptical of health authorities or fearful of government intervention have sometimes resisted testing and treatment, allowing the virus to spread unchecked through families and neighborhoods. The delay in mounting a coordinated global response has cost lives. Erica Tavares, a senior director at the International Medical Corps, acknowledged this plainly: by the time the world mobilized, months had already passed during which the disease had gained ground that should have been contested from the start.

The United States committed $512 million in direct aid and imposed a travel ban on non-citizens from affected regions, but the real work of containment falls to organizations embedded in Congo itself. Africa CDC, the African Union's disease control agency, partnered with the WHO to announce a joint response plan in June, estimating they would need more than $500 million over six months. Rather than imposing blanket travel restrictions, they released guidelines urging prevention measures like avoiding contact with bodily fluids—a more nuanced approach designed to maintain community cooperation.

Congo's National Institute for Biomedical Research has established laboratories in Ituri province, the outbreak's epicenter, to conduct testing and monitor the virus's genetic evolution. This genomic surveillance is essential both for containment and for informing vaccine development, which is already underway with clinical trials. Doctors Without Borders, which has operated in Ituri for more than twenty years, deployed over 1,400 workers to provide emergency medical care and disease surveillance. Kate White, an emergency medical coordinator working in Bunia, the provincial capital, emphasized that MSF's financial resources and organizational scale allow it to coordinate with local partners and distribute care efficiently across the region.

The International Medical Corps has established rapid response teams and treatment centers where patients receive medicine and monitoring, as well as facilities for those awaiting test results. But beyond immediate crisis response, IMC is investing heavily in training local health professionals—a deliberate strategy to build lasting capacity. Tavares explained that by equipping Congolese healthcare workers with the knowledge and skills to manage outbreaks, the organization aims to leave communities better prepared for future threats. IMC facilities will eventually be handed over to local leaders, and the organization is also addressing underlying vulnerabilities by improving water sanitation and hygiene infrastructure.

SOFEPADI, a Congolese nonprofit led by women, brings a different lens to the crisis. The organization focuses on preventing gender-based violence, reducing inequality, and empowering women to take control of their own healthcare—recognizing that disease outbreaks often deepen existing inequities and that women and girls face particular vulnerabilities during emergencies.

Twenty cases and two deaths have been reported in neighboring Uganda, though no new cases have appeared there since late June. The outbreak remains concentrated in Congo, where the combination of a rare, highly lethal virus, active conflict, community distrust, and limited vaccine options creates a perfect storm. The organizations working there are not waiting for headlines to return or for political will to wane. They are training, treating, and building—laying groundwork that may determine whether the next outbreak finds a population ready to respond or a region caught off guard once again.
