WHO reports that, as of 26 August, DRC has recorded 5,794 confirmed cases and 2,786 deaths across 60 health zones in six provinces. Including Uganda's 20 cases and two deaths and one imported case in France, the outbreak total is 5,815 cases and 2,788 deaths. At least 1,314 patients have recovered. In the latest 24-hour period, DRC reported 81 new confirmed cases from 19 health zones, while 82.3% of identified contacts were followed up. Health-worker vaccination with Ervebo began in parts of DRC on 27 August, with effectiveness against Bundibugyo virus in humans still unknown.

WHO published the report of the second IHR Emergency Committee meeting and confirmed that the DRC epidemic continues to meet the criteria for a Public Health Emergency of International Concern, but not a pandemic emergency. The Committee described the continued rapid growth and geographic expansion as a grave concern. Modelling presented to the Committee suggests substantial under-ascertainment, with true infections potentially three to four times higher than surveillance totals, and calls for urgent, intensified and sustained action centred on affected communities.

Uganda completed 42 consecutive days without a new confirmed case after the last imported patient was discharged on 16 July. The country reported 20 confirmed cases—15 imported and five locally acquired—along with 18 recoveries and two deaths; more than 800 contacts were identified and monitored. WHO and Africa CDC said sustained surveillance, testing capacity, infection prevention and cross-border coordination remain essential because transmission continues in neighbouring DRC.

DRC reported 72 additional confirmed cases and 35 deaths in the latest daily update, bringing the country total to 5,656 cases and 2,715 deaths. ECDC records 792 patients in isolation, 1,245 recoveries, 80.9% of identified contacts under follow-up, and transmission in 58 of 151 health zones across six provinces. DRC totals remain under continuous review and harmonisation.

WHO and Africa CDC leaders said the response must expand to two or three times its current capacity, prioritising hard-to-reach communities, frontline-worker protection, early detection, safe care, contact tracing, and safe burials. Their joint commentary reported that 158 health workers had been infected and 45 had died as of 20 August, while several health zones in northern Ituri and South Kivu had interrupted transmission.

WHO's updated temporary recommendations add detailed measures for surveillance, infection prevention, clinical care, community engagement, safe burials, domestic mobility, mass gatherings, logistics, and border health. WHO recommends exit screening and cross-border coordination but does not recommend blanket suspension of flights or waterways, or denial of entry to travellers and conveyances from affected states.

Using data through 23 August, WHO AFRO reported 5,584 confirmed cases and 2,680 deaths in DRC, an increase of 563 cases and 302 deaths from Situation Report 14. The report describes persistent transmission in Ituri, intensifying transmission in parts of North Kivu and Haut-Uele, and expansion to 57 affected health zones across six provinces.
