The Democratic Republic of the Congo is facing the largest Ebola outbreak in its recorded history, with confirmed infections surpassing the total from the country’s previous major epidemics. Government data reported 3,532 confirmed cases and 1,556 deaths as of July 31, 2026.
The outbreak is now the second-largest Ebola epidemic documented worldwide, behind only the 2014–2016 West Africa outbreak. Health agencies say transmission continues to outpace containment efforts in parts of eastern Congo.
The epidemic is caused by the Bundibugyo species of Ebola virus. Unlike the more familiar Zaire species, it has no approved vaccine or specific treatment. Experimental vaccines and medicines are being developed and tested, but they are not yet available for routine public use.

How Large Is the Ebola Outbreak in DR Congo?
The confirmed case count reached 3,532 by July 31, according to information released by the Congolese government. The reported death toll stood at 1,556.
Those figures make the epidemic larger by confirmed cases than the 2018–2020 outbreak in eastern Congo, which had previously been the country’s largest.
Only the West Africa epidemic of 2014–2016 was larger globally. That outbreak affected Guinea, Liberia and Sierra Leone and produced more than 28,000 recorded cases.
The current total may understate the true scale of transmission. World Health Organization officials have warned that weak surveillance and limited access to some communities mean the real number of infections might be substantially higher.
Where Did the Current Outbreak Begin?
Authorities confirmed the outbreak in May 2026 after detecting Ebola in northeastern Ituri Province. Later scientific analysis indicated that the virus may have been circulating undetected since at least January.
Cases have also been reported beyond the initial outbreak area, including parts of North Kivu and South Kivu.
Population movement between cities, rural communities, displacement camps and neighboring countries has made contact tracing more difficult.
Why Is This Outbreak Spreading So Quickly?
Several overlapping problems have weakened containment efforts.
Armed conflict continues across parts of eastern Congo. Insecurity makes some communities difficult or dangerous for medical teams to reach. Displacement also moves people between areas before symptoms or exposure histories are identified.
Health workers have reported shortages of vehicles, protective equipment, laboratory capacity, communications support and paid personnel. Delayed test results and incomplete reporting from clinics have also allowed some transmission chains to remain undetected.
Community mistrust presents another challenge. Some patients avoid testing or treatment centers because they fear isolation, lost income or poor conditions. Clinics may also hesitate to transfer patients if doing so affects their revenue.
What Is Bundibugyo Ebola Virus?
Bundibugyo virus is one of the Ebola virus species known to cause severe disease in humans. Previous outbreaks involving this species have occurred in Uganda and the Democratic Republic of the Congo.
Early symptoms often include fever, weakness, headache, muscle pain and fatigue. Vomiting, diarrhea, abdominal pain, rash and unexplained bleeding may develop as the illness progresses.
Symptoms can resemble malaria, typhoid fever and other common illnesses during the early stages. This makes testing essential for confirming an Ebola infection.
How Does Ebola Spread?
Ebola spreads through direct contact with the blood or other bodily fluids of an infected person who is sick or has died. Transmission can also occur through contaminated needles, clothing, bedding, medical equipment and other surfaces carrying infected fluids.
The virus does not spread as easily as measles, influenza or other common airborne infections. People are not generally considered contagious before symptoms begin.
Healthcare workers, caregivers and family members face higher risks when protective equipment and infection-control procedures are unavailable or used incorrectly.
Is There a Vaccine for This Ebola Outbreak?
No vaccine has been approved specifically for Bundibugyo virus.
The widely used Ervebo vaccine targets the Zaire species of Ebola and is not approved as protection against the Bundibugyo species involved in the current outbreak.
Research organizations and pharmaceutical partners are preparing experimental vaccine candidates for clinical trials. One project aims to manufacture tens of thousands of investigational doses using a platform related to the technology behind Ervebo.
Researchers are also evaluating experimental antiviral drugs and antibody treatments. Their safety and effectiveness against Bundibugyo virus have not yet been established for routine care.
What Is the WHO Doing?
The World Health Organization is supporting surveillance, laboratory testing, treatment facilities, infection prevention, safe burials and community outreach.
The outbreak was designated a Public Health Emergency of International Concern in May, signaling the need for coordinated international support.
Funding remains a major obstacle. Health agencies have warned that the response has received far less money than required to contain the epidemic and maintain services across affected areas.
Has Ebola Spread Outside DR Congo?
Uganda recorded 20 confirmed cases linked to the regional outbreak, including infections involving people who had traveled from Congo.
Ugandan authorities later declared the outbreak over after completing the required monitoring period without detecting further transmission.
No sustained spread outside the region had been reported in the latest information reviewed. Health authorities continue surveillance at borders and transportation routes.
What Has Been Confirmed
DR Congo reported 3,532 confirmed infections and 1,556 deaths by July 31.
The outbreak has become the largest recorded in the country and the second-largest documented worldwide.
Bundibugyo virus is causing the epidemic.
No approved vaccine or specific treatment currently exists for this Ebola species.
The outbreak has affected multiple areas in eastern Congo and has been complicated by conflict, displacement, limited resources and delayed detection.
What Remains Unknown
The true number of infections remains uncertain because surveillance does not reach every affected community.
Officials have not determined when transmission will peak or how long the outbreak will continue.
The effectiveness of experimental Bundibugyo vaccines and treatments will remain unknown until clinical testing produces reliable results.
The amount of international funding that will become available for the response is also uncertain.
How to Protect Yourself
- Avoid direct contact with the blood or bodily fluids of anyone suspected of having Ebola.
- Do not touch the body of someone who died from a suspected infection.
- Wash your hands with soap and safe water or an alcohol-based hand sanitizer.
- Do not handle contaminated clothing, bedding, needles or medical equipment without proper protection.
- Seek medical assistance immediately after a possible exposure.
- Tell healthcare workers about recent travel and contact with sick individuals.
- Follow official travel and health guidance from recognized public-health agencies.
- Do not spread unverified treatments, casualty figures or outbreak rumors online.
Explainedly Analysis
The scale of this outbreak reflects more than the characteristics of the virus. Ebola becomes harder to contain when detection is delayed and health teams cannot safely reach every patient, contact or community.
The absence of an approved Bundibugyo vaccine removes one of the strongest tools used during outbreaks involving the Zaire species. Response teams must rely heavily on testing, isolation, protective equipment, contact tracing, safe burials and public cooperation.
The immediate risk remains greatest for people living in affected communities and those caring for infected patients. The outbreak does not mean Ebola is spreading casually between countries or through normal social contact.
Reliable reporting matters during a health emergency. Case totals will continue changing, and official updates should take priority over unsupported claims about cures, international spread or hidden transmission.
Key Takeaways
- DR Congo is experiencing its largest recorded Ebola outbreak.
- The epidemic had reached 3,532 confirmed cases and 1,556 deaths by July 31.
- It is now the second-largest Ebola outbreak documented worldwide.
- The Bundibugyo species has no approved vaccine or specific treatment.
- Conflict, displacement, limited surveillance and funding shortages are slowing containment.
- Ebola spreads through direct contact with infected bodily fluids, not ordinary casual contact.
