WHO Struggles to Contain Deadly Bundibugyo Ebola Outbreak in Central Africa

The World Health Organization has admitted that the current Ebola outbreak in eastern Democratic Republic of the Congo, driven by the rare Bundibugyo strain, had a significant head start and may have begun circulating as early as January, months before it was detected in mid-May. ‘The outbreak had a big head start, and we’re still behind,’ WHO Director-General Tedros Adhanom Ghebreyesus told reporters in Geneva, even as he insisted that the international response is now ‘catching up.’ As of Wednesday, the DRC had recorded 344 confirmed cases and 60 deaths, while neighbouring Uganda reported 15 cases and one fatality—though some tallies put the numbers higher. Officials acknowledged that the virus has leapfrogged into new health zones such as Mambasa, more than 160 kilometres south of the epicentre in Ituri province, underscoring the uphill battle to contain its spread.

Containment efforts are being hampered by a formidable combination of factors that analysts in the region have described as particularly daunting, even by Congo’s experience of 17 previous Ebola outbreaks. Contact tracing remains critically low—only about 45 per cent of contacts have been identified, far below the 90 per cent threshold needed to break transmission chains. The Bundibugyo strain, named after a Ugandan border district where it was first identified, presents its own clinical hurdles: its symptoms closely mimic those of malaria, making initial diagnosis difficult, and no proven vaccine yet exists. Deep-seated community mistrust, stoked by decades of armed conflict and the presence of dozens of armed groups—including Islamic State-affiliated militants who launched an attack in the affected zone—has made surveillance and safe burials extremely hazardous. Mining activities in Ituri, which bring workers into close contact with potential animal reservoirs of the virus, add another layer of epidemiological risk.

The international response is also being undermined by what the WHO chief has labelled ‘blanket travel restrictions’ imposed by several nations. Canada recently suspended visa issuance for Congolese nationals and introduced a mandatory 21-day quarantine for travellers arriving from the DRC, Uganda, and South Sudan—a decision that has drawn sharp criticism from humanitarian organisations. Viewed from Ottawa, the measures are a prudent defence against importation of a lethal pathogen, but health authorities in Geneva argue that such bans disrupt the flow of critical supplies and personnel, violate international health regulations, and discourage countries from reporting outbreaks transparently. The WHO instead recommends exit screening at airports and border crossings to limit the risk of exportation while keeping supply chains open.

Financially, the operation is gasping for resources. The WHO estimates it needs $115 million over the next three months to mount an effective counteroffensive, yet only 35 per cent of that sum has been pledged. Without a rapid infusion of cash, the epidemic could lurch into neighbouring provinces and across porous borders into South Sudan, where health infrastructure is even more fragile. This is the third-largest Ebola outbreak in the DRC’s history, and while the global risk is classified as low, the national risk remains ‘very high.’ If the world does not accelerate its support, a pathogen that has already claimed dozens of lives may yet exact a far heavier toll across Central Africa.
