Congo Ebola Outbreak: Symptoms, Spread, and Latest Updates

When the World Health Organisation declared the latest Ebola outbreak in the Democratic Republic of the Congo a Public Health Emergency of International Concern in May 2026, the news sent ripples through global public health circles. For those of us who have followed the pattern of these outbreaks over the years, there was an immediate sense of déjà vu mixed with a new, sharper concern. This wasn’t the familiar Zaire strain that we have come to know and for which we have tools; it was the rarer Bundibugyo virus.

The outbreak has been spreading rapidly, primarily in the eastern DRC, with cases now confirmed in Uganda and even reaching as far as the United Arab Emirates through travel. At the time of writing, the numbers are sobering: 515 confirmed cases in the DRC with 91 deaths, alongside 19 confirmed cases in Uganda. The figures are climbing, but there is genuine hope—the case fatality rate currently stands at 17.4%, lower than in previous outbreaks, a testament to improved supportive care.

Ebola is a terrifying disease, but one we understand well. This article gives UK readers a clear, evidence-based picture of what is happening, how the virus spreads, what symptoms to look for, and what is being done to stop it.

What Is Ebola Virus Disease (EVD)?

Understanding the Ebola Virus

Ebola virus disease (EVD) is a rare but severe and often fatal illness caused by viruses belonging to the genus Orthoebolavirus. There are four species known to cause disease in humans: the Zaire virus, the Sudan virus, the Taï Forest virus, and the Bundibugyo virus. It is this final strain that is causing the current outbreak.

These viruses are zoonotic—they originate in animals and are then transmitted to humans. Fruit bats are considered the most likely natural reservoir. The virus does not exist in isolation; it lives in these animal hosts in the wild, and human infection is a rare “spillover event.”

History of Ebola Outbreaks in Africa

Ebola first emerged in 1976, with simultaneous outbreaks in the DRC (then Zaire) and South Sudan. The 2014–2016 West African outbreak was the most devastating on record, claiming over 11,000 lives and exposing the global community’s fragility when it comes to pandemic preparedness. Prior to the current outbreak, the DRC experienced a major outbreak from 2018 to 2020 (Zaire strain) and another as recently as 2025. This demonstrates that for the DRC, Ebola is not an isolated crisis but a recurring threat.

Why Congo Experiences Recurrent Ebola Outbreaks

The DRC’s vast equatorial forests are home to the natural reservoirs of the Ebola virus. The country’s decades of conflict, particularly in the eastern provinces, have created a perfect storm. Insecurity and population displacement make it difficult to track outbreaks, fragile health systems struggle to contain them, and the movement of people across borders can spread the virus to new areas.

Latest Updates on the Congo Ebola Outbreak

Current Situation and Affected Areas

The outbreak remains concentrated in Ituri Province, which accounts for 94% of confirmed cases in the DRC. However, the virus has spread to new health zones, prompting the WHO to raise the national risk assessment to “very high.”

Uganda is reporting cases that are epidemiologically linked to the DRC, with imported cases and secondary transmission to healthcare workers. There is no evidence of community transmission in Uganda at this stage, but the situation is being closely monitored.

Response from Health Authorities

The DRC’s Ministry of Health is leading the response. With support from WHO and partners, teams are intensifying surveillance, contact tracing, and patient care. This is a monumental task. At the time of publication, over 5,000 contacts were being traced, and laboratories are scaling up testing to clear backlogs. The DRC’s Government has shown its commitment, with the Minister of Health leading a joint mission to Bunia, the epicentre of the outbreak.

One major challenge is the absence of a licensed vaccine or specific treatment for the Bundibugyo strain. This means response efforts depend on “tried and tested” public health measures: rapid isolation, infection control, and community engagement. The Government and WHO are working to launch clinical trials for candidate vaccines and treatments, a vital step.

International Support and WHO Involvement

The international community has mobilised quickly. The Africa Centres for Disease Control and Prevention (Africa CDC) and WHO have launched a joint continental preparedness plan, requesting $518 million to support African countries. WHO has released funds from its Contingency Fund for Emergencies and deployed some of its most experienced field staff. The WHO is also coordinating with partners to advance clinical trials for promising monoclonal antibodies and antivirals.

What Causes Ebola Outbreaks?

Animal Reservoirs and Spillover Events

Ebola outbreaks begin with a spillover event. A person comes into contact with the blood, organs, or bodily fluids of an infected animal—most commonly fruit bats, but also primates (apes and monkeys) or forest antelopes. This can occur through handling or eating bushmeat or through exposure in areas where bats roost.

Human-to-Human Transmission

Once a person is infected, the virus can spread from person to person. The virus does not become contagious until the infected person develops symptoms. Human-to-human transmission occurs through direct contact with the blood, sweat, vomit, faeces, urine, breast milk, or semen of an infected person.

Factors That Contribute to Rapid Spread

Ebola spreads fastest in situations where people are in close contact with infected individuals and their bodily fluids. This is why healthcare workers and family members caring for sick relatives are at high risk if they do not use proper protective equipment. Cultural practices, such as certain funeral rites where mourners wash and touch the body of the deceased, have played a significant role in spreading the virus in past outbreaks. Insecurity in eastern DRC compounds these risks by limiting access and making it difficult to enforce infection control measures.

Symptoms of Ebola Virus Disease

Early Symptoms

The symptoms of Ebola can begin anywhere from 2 to 21 days after exposure. The early signs are non-specific and can easily be mistaken for other, less dangerous illnesses like malaria, typhoid, or influenza. These include a sudden fever, severe headache, muscle aches and weakness, fatigue, sore throat, and loss of appetite. The eyes may also become red.

Severe and Advanced Symptoms

Around the 10th day, the disease can enter a more severe phase, often involving gastrointestinal distress. This includes intense vomiting and diarrhoea, which can lead to severe dehydration. Patients may experience jaundice (yellowing of the skin and eyes) and a rash. In some cases, haemorrhagic symptoms appear—bleeding from the gums, nose, or internal organs, and bloody diarrhoea. This is the “bleeding” that Ebola is infamous for, though it is not always present. Ultimately, the disease can lead to organ failure, shock, and death.

When Medical Attention Is Needed

Because the early symptoms are so non-specific, a person who has been in an Ebola-affected area and develops a fever or malaise should isolate themselves immediately and seek medical attention, ensuring they inform the healthcare provider of their travel history. The CDC advises monitoring your temperature daily for 21 days after travel from an affected country and seeking medical care if you feel sick. Time is of the essence; the sooner a patient receives supportive care, the better their chance of survival.

How Does Ebola Spread?

Direct Contact with Bodily Fluids

The most common route of transmission is direct contact through broken skin or mucous membranes (like the eyes, nose, or mouth) with the bodily fluids of an infected person who has symptoms. The virus is present in high concentrations in vomit, diarrhoea, blood, and sweat.

Contaminated Surfaces and Materials

Ebola can survive for some time on surfaces. The virus can be transmitted from contaminated needles, bedding, clothing, or personal items. This is why safe handling and disposal of materials used by patients is critical.

Healthcare Settings and Exposure Risks

Health workers are at the frontline of exposure. In resource-poor settings, a lack of personal protective equipment (PPE) and proper infection prevention measures can lead to a rapid amplification of the outbreak. So far, 16 health and care workers have been confirmed infected in the DRC, highlighting the high risk.

Traditional Burial Practices and Transmission

In many cultures, families bathe and dress the body of a loved one as part of the funeral ritual. The dead body is highly infectious, and touching the deceased’s skin or fluids can easily transmit the disease. Modifying these practices to ensure safe, dignified burials is a crucial but culturally sensitive part of the response.

Is There a Risk of Ebola Reaching the UK?

International Travel and Border Monitoring

The WHO has repeatedly advised against any travel or trade restrictions based on currently available information. However, in a globalised world, the risk of an infected person flying to the UK is not zero. Countries like the US are assessing travelers from affected countries for symptoms, and similar protocols would be in place across Europe. The ECDC has assessed the risk of infection for the general population in the EU/EEA as very low.

UK Public Health Preparedness

The UK has robust public health infrastructure. The country has managed cases of viral haemorrhagic fevers before and has specialised isolation units at high-level hospitals. Our border health systems and point-of-entry screening procedures are designed to identify and isolate potential cases.

Actual Risk Assessment for UK Residents

For a UK resident who has not travelled to the DRC or Uganda, the risk is negligible. Ebola is not airborne; it requires direct contact with an infected person’s bodily fluids. The risk of importation is low, and the risk of onward transmission in the UK is even lower due to our high-quality healthcare and sanitation standards. The greatest risk is for UK nationals travelling to or living in affected areas.

Prevention Measures Against Ebola

Personal Protective Measures

For travellers: avoid contact with sick people, avoid handling or consuming bushmeat, and avoid contact with bats and non-human primates. Practise rigorous hand hygiene with soap and water or an alcohol-based sanitiser. Avoid healthcare facilities in outbreak areas unless you are ill.

Community-Level Prevention Strategies

The response depends on community trust. People need to understand the disease, recognise symptoms, and be willing to report cases and accept safe burials. Community engagement, particularly with local leaders, women’s groups, and religious leaders, is the cornerstone of control efforts.

Infection Control in Healthcare Facilities

Strict infection prevention measures are essential. This includes the use of full PPE, respirators, and goggles, and isolating suspected and confirmed cases. Ensuring that hospitals have adequate supplies and training is a priority.

Safe Burial and Contact Tracing Practices

Trained teams must conduct safe and dignified burials, using PPE and disinfecting the body and surrounding areas. Contact tracing is the detective work that finds everyone who has been exposed to a confirmed case and monitors them for 21 days to prevent further spread.

Ebola Vaccines and Available Treatments

Approved Vaccines

There is a significant challenge with this outbreak: the licensed vaccines are designed to protect against the Zaire ebolavirus, not the Bundibugyo strain. This is a critical distinction. While the Zaire vaccine is a powerful tool, it is not effective against the virus currently spreading. Researchers are now working to rapidly conduct clinical trials on candidate vaccines and treatments for this strain.

Available Treatments and Supportive Care

There is currently no specific antiviral treatment for Bundibugyo virus disease. Management relies on supportive care. This means treating the severe symptoms: rehydrating patients with intravenous fluids, balancing their electrolytes, maintaining oxygen levels, and supporting any failing organs. Access to this kind of advanced care can be the difference between life and death.

Why Early Detection Matters

Early detection of cases and rapid isolation are the most powerful tools we have. It breaks the chain of transmission and allows patients to get the supportive care they need before their organs fail. The faster a case is identified and contact tracing begins, the smaller the outbreak will be.

Global Impact of the Congo Ebola Outbreak

Public Health Consequences

The outbreak is a major strain on the DRC’s health system, already weakened by years of conflict and tackling other diseases like malaria, measles, and cholera. Diverting resources to Ebola means less attention on routine healthcare, which can lead to more deaths from otherwise treatable conditions. The global health community must also prepare for potential international spread, as seen with the cases in Uganda.

Economic and Social Effects

The outbreak affects every part of life. Schools may close, and economies can suffer as people avoid markets and trade is disrupted. The stigma associated with Ebola can tear communities apart. The fact that the outbreak is occurring in a conflict zone makes the response more expensive and complex, draining resources from humanitarian aid. The fear of the virus can lead to people avoiding clinics for other health issues, causing a secondary health crisis.

Lessons for Future Outbreak Preparedness

The current outbreak underscores the urgent need for a “pan-ebolavirus” vaccine—one that protects against multiple strains. It also highlights the importance of investing in local health systems in regions where diseases are most likely to emerge. The global community cannot afford to only respond to crises; we must be proactive in building resilient health structures and supporting local leaders who understand their communities best.
