WHO raises national risk to ‘very high’ for Bundibugyo Ebola outbreak in DRC
WHO upgrades national risk for Bundibugyo Ebola in the DRC to “very high,” citing confirmed cases and urging vigilance as neighboring countries intensify screening and tracing.
The World Health Organization has raised its assessment of the risk posed by the Bundibugyo strain of Ebola in the Democratic Republic of Congo to “very high” at the national level, while keeping the regional risk at “high” and the global risk at “low.” WHO Director‑General Tedros Adhanom Ghebreyesus said the revision follows new case confirmations and expanding suspect counts, noting that there is currently no licensed vaccine or specific approved treatment for the Bundibugyo strain. The declaration has prompted stepped‑up surveillance and cross‑border coordination in the Great Lakes region.
WHO changes national risk rating
WHO’s director‑general told reporters the agency had “adjusted our risk assessment to very high at the national level, high at the regional level and low at the global level.”
The reassessment reflects both the number of confirmed infections and a large number of suspected cases and deaths under investigation, according to the statement. WHO emphasized that the move is intended to mobilize resources and encourage intensified public health measures inside the DRC.
Confirmed figures and suspected toll in the DRC
Health authorities in the DRC have reported 82 confirmed cases of infection linked to the Bundibugyo strain.
Of those confirmed, seven deaths have been officially recorded, while an additional 177 deaths are suspected to be associated with the outbreak and remain under investigation. Nearly 750 suspected cases are being monitored, according to the figures released alongside the WHO assessment.
Uganda’s response and containment measures
Neighboring Uganda has activated emergency measures after detecting potential exposures linked to the outbreak, implementing rigorous contact tracing and cancelling large public gatherings.
WHO noted that Uganda’s intensified case finding and social distancing measures appear to be effective in interrupting transmission chains at this stage, highlighting the importance of rapid response in border areas.
No licensed vaccine or approved treatment for Bundibugyo strain
Public health officials have underscored a critical concern: unlike some other Ebola strains, Bundibugyo currently has no licensed vaccine or proven, approved therapeutic agents specific to it.
The absence of approved countermeasures increases reliance on classic public health interventions—testing, isolation, contact tracing and community engagement—to limit spread and reduce fatalities.
International monitoring and cross‑border movements
WHO reported that one person of U.S. nationality who had been in contact with a high‑risk individual was transferred to the Czech Republic, and that authorities are following other cross‑border contact reports.
Officials stressed the need for coordinated screening at points of entry and rapid information sharing between countries to prevent exportation of cases and to ensure appropriate clinical follow‑up for contacts.
Public health priorities and operational challenges
WHO and national authorities are prioritizing rapid diagnostic testing, safe and dignified burial procedures, and the protection of frontline health workers.
Operational challenges include reaching remote communities, ensuring reliable laboratory confirmation, and scaling up infection prevention and control measures in health facilities that already face resource constraints.
Local and international agencies are also working to communicate risk clearly to affected communities to reduce stigma and encourage early reporting of symptoms. Community acceptance of contact tracing and isolation is being presented as essential to containing the outbreak.
The situation remains fluid as health teams investigate additional deaths and suspected cases, and as regional partners reinforce surveillance at borders and transit hubs. Public health officials say vigilance, rapid testing, and cooperative international support will be central to preventing further spread of the Bundibugyo Ebola outbreak.
