The Ebola outbreak spreading across eastern Democratic Republic of the Congo and into Uganda has killed at least 131 people from more than 500 suspected cases, prompting the Africa Centres for Disease Control and Prevention to declare a continental emergency and the World Health Organization to express alarm at the epidemic's trajectory [2][7]. The escalation follows the WHO's declaration of a Public Health Emergency of International Concern (PHEIC) — the first time a director-general has issued such a designation before convening an emergency committee [10][33]. Governments from Singapore to Italy to India have since activated traveler monitoring, while the United States has imposed entry restrictions on non-citizens from affected countries, drawing criticism from medical associations and the Africa CDC itself [5][8][14][35].

DR Congo Health Minister Samuel Roger Kamba reported roughly 131 deaths and around 513 suspected cases, cautioning that not all reported deaths have been confirmed as Ebola [6]. WHO Director-General Tedros Adhanom Ghebreyesus said he was "deeply concerned about the scale and speed of the epidemic" [2]. Africa CDC Director Jean Kaseya declared the continental emergency, describing the outbreak as occurring in one of the continent's most complex operational areas, marked by insecurity, population movements, and fragile health systems [7]. Mathematical modelling by the MRC suggests actual case numbers may already exceed 1,000 [16].

A central factor in the outbreak's rapid growth was delayed detection. WHO representative in the DRC Anne Ancia explained that the province's laboratory "solo tenía reactivos para la cepa Zaire, por lo que las pruebas daban negativo" (only had reagents for the Zaire strain, so tests came back negative), causing initial cases to be misdiagnosed as malaria or salmonellosis [9]. Jean-Jacques Muyembe, the Congolese scientist who co-discovered the Ebola virus, warned that "frankly, at this point nobody can give a figure. Nobody has a grip on the numbers" [3]. The International Rescue Committee attributed the surveillance failure in part to cuts in international donor funding [3], with Ancia noting a 73 percent reduction in water and sanitation funding in the affected region [9].

The absence of an approved vaccine or treatment for the Bundibugyo strain — genetically distinct from the Zaire strain targeted by existing vaccines — has left responders reliant on traditional public health measures. Africa CDC Director Kaseya told RFI he was in "panic mode" over the lack of countermeasures [18][22]. Ancia said international experts were working with institutions including the University of Oxford and hoped to have vaccine candidates in trials within two months, though she cautioned: "I don't think that in two months we will be done with this outbreak" [11][10]. Mosoka Fallah, acting director of the Africa CDC's science department, said the agency would "look at what evidence we have and make a decision" on the best approach for a strain without countermeasures [2].

The operational environment compounds the medical challenge. Eastern DRC's Ituri province, the outbreak's epicenter, has seen over 100,000 people newly displaced by armed conflict since late 2025 [10]. Heather Kerr, the IRC's DRC country director, said "years of conflict and displacement have left health systems on their knees" [18]. Oxfam's DRC country director Manenji Mangundu described the outbreak as "hitting a country already stretched to breaking point" [18]. Maximilian Gertler, a tropical medicine specialist at Berlin's Charité hospital, called Ebola an "Armutserkrankung" (disease of poverty) driven by miserable living conditions, lack of clean water, and distrust of authorities [19].

Residents of Ituri described widespread fear and economic hardship. Gloire Mumbesa, a resident of Mongbwalu, said: "On public transport, in bars and at mass gatherings, everyone is talking about Ebola. The fear is that this disease may spread to many other areas" [18]. Dieudonné Lossadekana in Bunia said: "We're stunned by the resurgence of Ebola in our region. We've already recorded several dozen deaths. For us, it's heartbreaking" [18]. Claude Kasuna in Irumu territory noted that poverty compounds the crisis: "When a health emergency like this one strikes, it hits us hard economically" [18]. Former Mongbwalu mayor Jean Pierre Badombo traced the local spread to a large open-casket funeral procession that arrived from Bunia in mid-April, after which "we experienced a cascade of deaths" [18].

Governments outside Africa have split on how to respond. The United States banned entry for non-citizens who have been in DR Congo, South Sudan, or Uganda in the prior 21 days and suspended visa services in the two affected countries [8][14][34]. The Infectious Diseases Society of America criticized the policy, stating that "las políticas de salud pública que discriminan a los ciudadanos no estadounidenses no impedirán que los virus crucen nuestras fronteras. Las enfermedades no reconocen pasaportes" (public health policies that discriminate against non-US citizens will not prevent viruses from crossing our borders. Diseases do not recognize passports) [8]. The Africa CDC also criticized the US decision [14].

By contrast, Italy activated health surveillance for personnel returning from the outbreak zones without imposing an entry ban [1]. Singapore required incoming travelers from affected areas to self-monitor for 21 days, with Health Minister Ong Ye Kung predicting "many more deaths and infections in the coming days and weeks" [5]. Turkey, Japan, and India each issued risk-based travel advisories and enhanced airport surveillance while stopping short of blanket restrictions [28][32][35]. German Federal Health Minister Nina Warken stated the risk to Germany was "extremely low" and that "im Land braucht es derzeit keine Vorkehrungen" (no precautions are needed in the country at this time), adding that a global Ebola pandemic was "nearly impossible" [19]. Mexican epidemiologist Alejandro Macías similarly assessed the pandemic risk as low but called Ebola the more concerning disease due to its ease of transmission and the current variant's lack of response to existing vaccines [17].

Regional actors have mobilized their own responses. Rwanda closed its border with DR Congo after a confirmed case appeared in Goma [4][29]. Uganda's President Yoweri Museveni told citizens to avoid hugging and shaking hands and postponed the Martyrs' Day pilgrimage [4]. The East African Community urged partner states to activate preparedness plans and enhance screening at border crossings [15]. Russia announced it would send Rospotrebnadzor epidemiological specialists and diagnostic tests to Uganda at Kampala's request [15][27]. The AFC-M23 rebel group, which controls parts of eastern DRC, said it had "immediately activated" health response mechanisms in its territories [4].

The WHO emergency committee is set to convene to discuss vaccine options and response coordination, while Germany prepares to treat an evacuated US missionary doctor who contracted the virus in the DRC [2][6][8][13]. Ancia warned that the more the WHO investigates, "the more we realise that it has already disseminated at least a little bit across border and also in other provinces" [16].
