A fast-growing Ebola outbreak in the Democratic Republic of Congo (DRC) and neighbouring Uganda is raising fears of a wider regional health crisis, as authorities struggle to contain the rare Bundibugyo strain of the virus—an Ebola variant for which there is no approved vaccine or specific treatment.
The outbreak, first declared in eastern DRC on 15 May 2026, has already become one of the country’s most serious Ebola emergencies in recent years. Within weeks, infections had crossed into Uganda, prompting the World Health Organization (WHO) to declare the outbreak a Public Health Emergency of International Concern (PHEIC), its highest level of global health alert.
Health officials say the outbreak is being driven by a combination of conflict, population displacement, weak healthcare systems and the movement of people across porous borders—factors that have historically complicated efforts to contain Ebola in the region.
A RARE AND DANGEROUS STRAIN
Unlike the Zaire strain of Ebola, against which vaccines and treatments have been developed, the Bundibugyo strain remains largely uncharted territory for public health authorities.
According to the WHO, previous outbreaks of Bundibugyo virus disease recorded fatality rates ranging from 30% to 50%, making rapid detection and supportive medical care crucial for survival. Yet there is currently no licensed vaccine or approved therapeutic specifically designed to combat this strain.
The outbreak was first detected in Ituri Province in eastern DRC before spreading into North Kivu and South Kivu provinces. Ugandan authorities later confirmed imported cases linked to travellers arriving from the DRC, highlighting the risks posed by frequent cross-border movement.
CASES CONTINUE TO RISE
The scale of the outbreak has expanded rapidly.
Recent reports indicate that nearly 900 confirmed cases have now been recorded across the two countries, with more than 200 deaths reported. The vast majority of infections remain concentrated in the DRC, while Uganda has recorded a smaller but growing number of cases linked to both imported infections and local transmission.
Public health experts warn that the official figures may represent only a fraction of the true toll.
Insecurity in conflict-affected areas, limited testing capacity, and difficulties tracing contacts have hampered surveillance efforts. In some communities, mistrust of health authorities has led families to hide sick relatives or conduct traditional burials outside official protocols, increasing the risk of further transmission.
The outbreak has also spread into displacement camps housing people fleeing violence, heightening concerns that overcrowded conditions could accelerate infections.
WHY THE WORLD IS CONCERNED
The WHO’s decision to declare a global health emergency reflects growing concern over the outbreak’s international implications.
Cross-border transmission between the DRC and Uganda, combined with the absence of approved medical countermeasures, significantly increases the risks posed by the outbreak. WHO and Africa CDC officials have repeatedly warned that without stronger international support, the situation could deteriorate further.
International agencies including the WHO, Africa CDC and Médecins Sans Frontières are supporting response efforts through surveillance, laboratory testing, contact tracing, treatment centres and community engagement campaigns. A continental preparedness plan worth more than $500 million has also been launched to strengthen regional readiness.
Yet funding gaps remain a major challenge, with health agencies warning that only a fraction of pledged resources has reached frontline responders.
UNDERSTANDING THE VIRUS
Ebola spreads through direct contact with the blood or bodily fluids of an infected person, including saliva, vomit, urine and sweat. The virus can also be transmitted through contact with contaminated clothing, bedding or medical equipment.
Symptoms often begin with fever, fatigue, muscle pain and headache before progressing to vomiting, diarrhoea and, in severe cases, internal and external bleeding.
While no specific treatment exists for the Bundibugyo strain, early supportive care—including hydration, oxygen support and blood pressure management—can significantly improve a patient’s chances of survival.
THE BIGGER LESSON
For a region that has battled multiple Ebola outbreaks over the past two decades, the latest crisis is a stark reminder that infectious diseases remain a major threat to public health and economic stability.
The outbreak underscores the importance of strong health systems, rapid disease surveillance and cross-border cooperation. But experts say the most critical factor may be community trust.
Without local participation, even the best-funded response efforts can struggle to contain a virus that spreads through close human contact.
As health workers race to break chains of transmission, the coming weeks may determine whether Central Africa succeeds in containing another Ebola outbreak—or faces a crisis with consequences far beyond its borders.
