Uganda is drawing on decades of hard-won experience battling Ebola as a fast-moving outbreak originating in eastern Democratic Republic of Congo crosses borders and places the region under mounting pressure. Ugandan authorities officially declared a new outbreak on 15 May 2026, after Congolese nationals who had been exposed to the virus in DRC's Ituri Province crossed into Uganda seeking medical care. Within days, confirmed cases had spread to a Ugandan driver who transported the patients and to healthcare workers at medical facilities in Kampala, the capital.

The outbreak is caused by the Bundibugyo strain of Ebola, for which there is currently no approved vaccine or specific treatment — a fact that has sharpened concern among regional health officials. As of 27 May, Ugandan authorities say all identified cases remain linked to a single transmission chain originating with the two initial patients from DRC, a finding they describe as cautiously reassuring. More than 600 health workers have been deployed to review months of hospital records, trace patient movements and identify any unexplained deaths, while all 37 districts bordering DRC have been placed under enhanced surveillance. "We are in a race against the clock," acknowledged Daniel Kyabayinze, director of public health at Uganda's Ministry of Health, noting that the first patients had already entered the Ugandan health system around 10 May — days before the outbreak was formally declared. Health authorities are now watching closely for the 21-day mark, which corresponds to Ebola's maximum incubation period; if no unexpected new clusters emerge, Kampala hopes to confirm the outbreak remains contained within one transmission chain.

The broader regional picture is considerably more alarming. Inside DRC's Ituri Province — a conflict-affected area where armed violence has displaced populations and restricted humanitarian access — hundreds of suspected infections and scores of deaths have been recorded, concentrated in the health zones of Mongbwalu, Rwampara and Bunia. Early laboratory delays compounded the crisis: local testing facilities in Bunia were initially configured to detect the more common Ebola Zaire strain, not the Bundibugyo variant, forcing samples to be flown nearly 3,000 kilometres to Kinshasa for confirmation. "The laboratory in Bunia could not detect the Bundibugyo strain," DRC Health Minister Roger Samuel Kamba told a joint briefing in Kampala on 23 May, organised by the Africa Centres for Disease Control and Prevention. "Conflicts prevent us from having a global response," he added. Emergency coordination meetings convened in Kampala over the weekend of 22–24 May brought together ministers of health, epidemiologists, humanitarian agencies and diplomats in what participants described as an atmosphere of acute regional urgency.

Uganda has framed its own record as a source of confidence. "We have never exported Ebola," said Dr Diana Atwine, Uganda's Permanent Secretary at the Ministry of Health, addressing development partners on 22 May. "For the nine epidemics we have had with Ebola, not even one. That is our commitment." The country has spent two decades building specialised surveillance systems, laboratory networks and rapid response teams, and is now activating emergency preparedness measures across 29 high-risk districts. The outbreak's reach has already prompted international vigilance: in Bengaluru, India's southern technology hub, a 28-year-old Ugandan national was placed in isolation after developing mild symptoms including body ache. She tested negative for Ebola at India's National Institute of Virology in Pune, and India's Health Ministry confirmed there is no confirmed case on Indian soil. New Delhi had issued a travel advisory the previous Saturday urging citizens to avoid non-essential travel to DRC, Uganda and South Sudan after the WHO declared the outbreak a global public health emergency.

Public health officials stress that while the situation in Uganda remains manageable for now, the outcome may ultimately depend on what happens inside eastern DRC, where insecurity, misinformation and overstretched health systems continue to create conditions in which the virus can spread beyond the reach of conventional containment. The Uganda-DRC border is one of East Africa's busiest frontiers, crossed daily by traders, refugees, patients and schoolchildren — making comprehensive monitoring an enormous logistical challenge. Authorities are urging the public to report suspected cases, noting that community alerts, even when most turn out to be false alarms caused by more common illnesses such as malaria, are critical to detecting any emerging secondary chains before they take hold.
