Ebola Outbreak in DR Congo and Uganda: What We Know About Cases, Deaths, and Regional Risk

Early outbreak updates from health authorities reported:

• 336 suspected cases of Ebola virus disease
• 88 deaths associated with the outbreak

These figures were cited in updates from the Africa Centres for Disease Control and Prevention (Africa CDC) and reported by international media during the early phase of the emergency declaration.

Public health experts caution that the true scale may be larger, since suspected cases often outnumber confirmed laboratory diagnoses during the initial stages of Ebola outbreaks.

The virus strain behind the outbreak

The current outbreak is caused by the Bundibugyo strain of Ebola virus (Bundibugyo ebolavirus).

This strain is less common than the Zaire strain that caused the massive West African epidemic in 2014–2016, but it still produces severe hemorrhagic fever with high fatality rates. A key concern for health officials is that no licensed vaccine specifically targets the Bundibugyo strain, limiting the immediate vaccination tools available to control transmission.

Because of these uncertainties and the growing number of suspected infections, global health authorities moved quickly to escalate the response.

WHO declares a global health emergency

On 17 May 2026, the World Health Organization (WHO) declared the outbreak a Public Health Emergency of International Concern (PHEIC) under the International Health Regulations.

A PHEIC is the WHO’s highest alert level for outbreaks that risk spreading internationally. The designation enables stronger global coordination, resource mobilization, and surveillance across borders.

However, WHO clarified that the situation does not meet the criteria for a “pandemic emergency,” a newer classification introduced after COVID‑19.

Africa CDC declares a continental emergency

In addition to the WHO declaration, the Africa Centres for Disease Control and Prevention (Africa CDC) issued its own high‑level alert, declaring the outbreak a Public Health Emergency of Continental Security.

This move allows Africa CDC to coordinate a regional response, deploy emergency teams, and strengthen surveillance and preparedness across African Union member states.

Ten African countries at risk of spread

Africa CDC warned that 10 additional African countries face elevated risk of Ebola transmission because of travel links and shared borders with affected regions. According to the agency, the countries at risk include:

• Angola
• Burundi
• Central African Republic
• Republic of Congo
• Ethiopia
• Kenya
• Rwanda
• South Sudan
• Tanzania
• Zambia

Except for Ethiopia, most of these countries share land borders with either the DRC or Uganda, which increases the likelihood of cross‑border spread if surveillance and containment measures fail.

International responses and travel precautions

Several international responses followed the emergency declaration.

The U.S. Centers for Disease Control and Prevention (CDC) said it had mobilized response activities and issued health advisories for clinicians and public‑health officials regarding the outbreak in DRC and Uganda.

Governments and organizations outside Africa also took precautionary steps. For example, India postponed the Fourth India–Africa Forum Summit, originally scheduled for late May 2026 in New Delhi, citing the evolving Ebola situation on the continent.

Such measures are aimed at reducing risk while authorities assess how widely the virus may spread.

Why health experts remain concerned

Several factors make the outbreak particularly worrying:

• Cross‑border spread has already occurred between DRC and Uganda.
• The outbreak involves a strain without a widely available vaccine.
• Early surveillance data suggests the outbreak may be larger than initial confirmed numbers indicate.

Health agencies emphasize that rapid detection, isolation of patients, contact tracing, and community engagement are essential to stopping further transmission.

While the immediate risk outside the affected region remains low, global health authorities are closely monitoring the situation as response teams work to contain the outbreak in Central Africa.
