The World Health Organization (WHO) declared the Ebola outbreak in the Democratic Republic of the Congo (DRC) and Uganda a public health emergency of international concern on May 16, 2026, citing 80 suspected deaths and 246 suspected cases in DRC’s Ituri province, along with two confirmed cases in Uganda.
WHO’s Declaration and Context
The World Health Organization (WHO) elevated the Ebola outbreak in the Democratic Republic of the Congo (DRC) and Uganda to a public health emergency of international concern on May 16, 2026, marking the second-highest level of alert since 2024. The decision follows reports of 80 suspected deaths and 246 suspected cases in DRC’s Ituri province, alongside two confirmed cases in Uganda, including one fatality. The virus responsible is the Bundibugyo strain, which lacks specific antiviral treatments or approved vaccines, according to the agency.
WHO emphasized that the outbreak, first identified in Ituri province, has spread to urban centers, including the DRC’s capital, Kinshasa, and Uganda’s capital, Kampala. The agency cited “high positivity rates in initial samples” and a “rising number of reported suspected cases” as factors in its declaration. The move aims to mobilize international support and prepare neighboring countries for potential cross-border transmission.
Epidemiological Details and Challenges
As of May 16, 2026, DRC’s Ituri province reported 80 suspected Ebola-related deaths, with eight laboratory-confirmed cases and 246 suspected cases. In Uganda, two confirmed cases were recorded, including one death among individuals who had traveled from the DRC. The Bundibugyo strain, first identified in 2007, has a fatality rate of approximately 25%, according to WHO data. Unlike the more lethal Zaire strain, which has targeted vaccines, the Bundibugyo variant remains without specific therapeutic options.

WHO noted that the outbreak’s geographic spread and limited diagnostic capacity in affected regions complicate containment efforts. The agency highlighted the need for “immediate isolation of confirmed cases” and “contact tracing” to curb transmission. However, it warned against border closures or travel restrictions, stating such measures could exacerbate informal movement and hinder public health coordination.
Response and International Coordination
WHO urged affected nations to prioritize surveillance, community engagement, and resource allocation to address the outbreak. The agency emphasized the importance of “transparent data sharing” and “international collaboration” to prevent regional escalation. In a statement, WHO’s emergency committee noted that while the outbreak does not meet the threshold for a pandemic alert, its potential for cross-border spread necessitates heightened vigilance.
Regional health authorities, including the African Centres for Disease Control and Prevention (Africa CDC), have initiated rapid response teams to support DRC and Uganda. These efforts include deploying mobile testing units, distributing personal protective equipment, and launching public awareness campaigns. However, logistical challenges, including insecurity in Ituri province and limited healthcare infrastructure, remain significant barriers to containment.
International Implications and Next Steps
The WHO’s declaration underscores the urgency of global preparedness for emerging infectious diseases. While no travel bans have been recommended, the agency advised countries to enhance screening at border crossings and monitor travelers from affected regions. WHO also called for increased funding to support vaccine development and distribution, citing the lack of targeted interventions for the Bundibugyo strain.
As of May 17, 2026, the outbreak’s trajectory remains uncertain. WHO will continue to assess the situation, with a focus on preventing further urban spread and addressing gaps in community trust. The agency reiterated that “the risk of international spread is high, but manageable with coordinated action.” Health officials worldwide are monitoring the situation closely, as the outbreak highlights ongoing vulnerabilities in global health security.
