Confirmed Ebola cases in the Democratic Republic of the Congo nearly doubled in two days to 225, with more than 1,000 suspected cases and at least 246 deaths (with some sources reporting 220 suspected deaths) reported by the Africa Centres for Disease Control and Prevention, as WHO Director-General Tedros Adhanom Ghebreyesus arrived at the outbreak's epicenter in Bunia, Ituri province [2][5][6]. The outbreak, caused by the Bundibugyo strain of the Ebola virus — for which no licensed vaccine or approved therapy exists — has spread to Uganda, where nine confirmed cases and one death have been recorded, and prompted Brazil to investigate a suspected case in São Paulo [2][1][8].
Tedros, speaking in Bunia, framed community ownership and government leadership as the pillars of the response. "We are not here to tell people what to do. We are here to listen. Communities understand their own challenges and their own solutions," he stated [4]. He expressed confidence in the DRC's capacity, noting the country has faced Ebola sixteen times before and ended every outbreak, in what he called the country's 17th Ebola outbreak [12]. DRC Health Minister Samuel Roger Kamba Mulamba echoed that position: "We defeated Ebola last year. We tell you, trust us, we know what we are doing" [6]. Kamba also ruled out closing schools despite at least five student deaths, saying the government would instead strengthen preventive measures [15]. Tedros urged safe burial practices, warning that bodies of Ebola victims are highly contagious: "While we grieve for those we have lost, we must do everything we can so that we do not lose another" [5][6].
Doctors Without Borders offered a starkly different assessment of the same situation. Dr. Alan Gonzales, MSF's deputy director of operations, stated: "Two weeks after the declaration of the Ebola disease outbreak in Ituri Province, the situation is deeply alarming. Never before has an Ebola outbreak recorded so many cases so soon after its declaration" [5]. Dr. Gonzales added: "Nadie conoce la verdadera magnitud y gravedad de este brote" (Nobody knows the true magnitude and severity of this outbreak) [7]. MSF reported that hundreds of samples remain untested and that the number of deployed medical organizations falls far short of what is needed [11][9]. The DRC health minister rejected the characterization that the outbreak is "out of control," asserting that health officials have sufficient testing resources [11].
The absence of pharmaceutical tools for the Bundibugyo strain sets this outbreak apart from recent Ebola emergencies. WHO has identified IAVI's rVSV Bundibugyo and Oxford/Serum Institute's ChAdOx1 Bundibugyo as the leading vaccine candidates, but both remain in pre-efficacy stages [30]. Le Monde reported that clinical lot production alone would require six to nine months, and no Phase 1 trials had begun when the outbreak was declared [21]. The case fatality rate for the Bundibugyo strain ranges between 30 and 50 percent based on previous outbreaks [2][8].
Border closures and travel restrictions have become a central fault line. Tedros urged countries including Canada, the United States, Rwanda, and Uganda to reconsider restrictions, arguing they discourage transparency in reporting cases [4]. Katrine L. Wallace, an epidemiologist at the University of Illinois Chicago, wrote that both Uganda's border closure and the US plan to quarantine exposed Americans in Kenya "rely on a common assumption: that creating geographic distance from a threat provides protection. However, surveillance, isolation and response capacity are often more important" [14]. Xinhua reported that WHO does not recommend travel bans, deeming them of limited effect [32]. The US, Mexico, and Canada, however, announced aligned public health travel measures for individuals arriving from affected African regions, citing the need to protect citizens and visitors during the FIFA World Cup 2026 [3].
The US State Department described the United States as the largest financial contributor to the Ebola response, with over $162 million committed, and detailed the deployment of 1,300 health workers in the DRC and procurement of personal protective equipment [3]. That framing contrasts with reporting that global funding for the response has more than halved, from $498 million to $219 million, according to the Africa CDC [2]. STAT News reported that prior US aid cuts had left DRC surveillance and community alert systems degraded before the outbreak began [28]. WHO has received only a third of the funding required for the current response, Tedros stated [11]. DW News noted that the US withdrawal from WHO compounds the challenge [6].
A separate dispute has emerged over a US plan to establish an Ebola quarantine facility for American citizens at a military airbase in Kenya. A Kenyan High Court suspended the project after the Katiba Institute, a rights group, challenged its legality and transparency [26][27]. The Africa CDC warned the facility would strain Kenya's health system [2]. Kenyan Health Minister Aden Duale later said the project would proceed, without mentioning the court ruling [2].
Women in eastern DRC face disproportionate risk because they serve as primary caregivers to the sick and the dead, according to Al Jazeera and the humanitarian organization CARE [13][29]. Shortages of protective equipment amid funding cuts are increasing their exposure, with broader gender impacts including reduced health access and increased gender-based violence [13][29].
Brazilian authorities investigating the suspected case in São Paulo — a 37-year-old Congolese man who recently traveled to the DRC and is now intubated in critical condition — assessed the risk of Ebola introduction into Brazil and South America as very low. The São Paulo State Health Secretariat cited "a ausência histórica de transmissão autóctone no continente sul-americano, a inexistência de voos diretos entre a região afetada e a América do Sul" (the historical absence of autochthonous transmission on the South American continent, the nonexistence of direct flights between the affected region and South America) [1]. The patient is in isolation at the Emílio Ribas Institute of Infectology, and protocols including immediate notification and laboratory investigation are in place [16].
Dorcas Mapenzi, a resident of the Kingonze displacement camp in Ituri, stated: "If Ebola comes, we'll be wiped out as we're packed like sardines" [9]. The outbreak area is also affected by armed conflict, including M23 rebel activity, which obstructs humanitarian access [6][23]. Tedros called for a ceasefire to strengthen the health response [10]. A new laboratory in Bunia can now return test results within 24 hours, eliminating the need to transport samples to Kinshasa [5]. The next hearing on the Kenyan quarantine facility is scheduled for June 2 [27].
