Ebola outbreak in DRC and Uganda is spreading across borders as response teams face access gaps

The Bundibugyo virus outbreak in the Democratic Republic of the Congo and Uganda has reached 134 confirmed cases and 18 confirmed deaths across both countries, according to a WHO Disease Outbreak News update. The agency says the event is evolving rapidly, with increasing case numbers, geographic spread and ongoing cross-border transmission.

The outbreak is concentrated in DRC’s Ituri, North Kivu and South Kivu provinces, WHO reported. Uganda has recorded nine confirmed cases, with at least three linked to travel from DRC, according to the European Centre for Disease Prevention and Control. WHO also reported one confirmed case involving a person from the United States who had treated patients in DRC and is receiving care in Germany.

The case picture is still changing. WHO reported 906 suspected cases and 223 deaths among suspected cases in DRC as of 27 May. ECDC said DRC authorities later revised some suspected figures by removing non-cases and reclassifying some cases as confirmed. As of 29 May, ECDC cited DRC’s health ministry reporting 125 confirmed cases, including 17 deaths, and 906 suspected cases, including 223 deaths.

The Guardian reported that WHO placed the death rate for confirmed Ebola cases in DRC between 30% and 50%. Anaïs Legand, from WHO’s high threat pathogens team, said the estimate meant up to five out of 10 people were likely to die. WHO also said a patient recovered and was discharged from a DRC health centre on 27 May after two negative tests, the first confirmed recovery in the outbreak.

WHO Director General Tedros Adhanom Ghebreyesus arrived in Kinshasa to support containment efforts, The Guardian reported. He was due to travel to the centre of the outbreak in north-eastern Ituri province, though the trip was delayed by a day. Tedros called for a ceasefire among armed groups to help prevent deaths from a disease he said could be stopped.

The response problem is not only medical. WHO says contact tracing and follow-up are being complicated by insecurity, inadequate isolation, care and referral systems. Those are the systems that determine whether suspected cases are found quickly, whether patients can be moved safely, whether health workers can protect themselves and whether communities receive clear guidance before transmission widens.

National authorities, WHO and partners are deploying rapid response teams, delivering medical supplies, strengthening surveillance and laboratory confirmation, improving infection prevention and control, setting up safe treatment centres and working on community engagement, according to WHO. Those measures depend on access to affected areas and enough public-health capacity to keep pace with new cases.

The Standard reported that WHO had declared the outbreak a Public Health Emergency of International Concern and that Hong Kong activated an Emergency Response Level under its Ebola preparedness plan. The supplied WHO excerpt confirms a rapidly evolving cross-border outbreak and response measures, but it does not itself include the PHEIC declaration language, so that claim should be treated as reported by The Standard rather than independently confirmed by the WHO excerpt provided here.

Risk is being assessed differently by location. ECDC said the likelihood of infection for people living in the EU/EEA remains very low, while continuing to monitor the situation. That does not reduce the operational pressure in affected parts of DRC and Uganda, where confirmed and suspected cases, insecurity and weak referral systems are already shaping the outbreak response.

The cleanest implication is that Ebola control now depends as much on access and public-health logistics as on formal alerts. The outbreak can only be contained if tracing, isolation, treatment, supply delivery and community trust move faster than cross-border transmission.
