On 16 May 2026, the World Health Organisation declared the Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda a Public Health Emergency of International Concern (PHEIC) - its second-highest global alert level. As of 25 May 2026, 906 suspected cases and 223 suspected deaths have been reported in DRC, with 7 confirmed cases in Uganda. An American healthcare worker responding to the outbreak tested positive on 17 May. The situation is changing rapidly.
I’ve spent a significant part of my career dealing with infectious disease outbreaks, and the questions raised about this one are understandable. I’ll try and answer some of these - what this outbreak is, why this strain is particularly challenging, the realistic risk to people in the UK, and what anyone travelling to Central or East Africa needs to do right now.
What is Ebola?
Ebola is a severe viral illness first identified in 1976 near the Ebola River in what is now the DRC. It belongs to a group of viruses called orthoebolaviruses, and it causes a condition known as viral haemorrhagic fever - a serious illness that can affect multiple organs and, in the worst cases, trigger internal and external bleeding.
Since 1976, Ebola has caused more than 40 documented outbreaks and killed approximately 15,000 people, almost all in Africa. This is the DRC’s 17th Ebola outbreak, which is why - despite the enormous challenges - the DRC has developed a more experienced outbreak response infrastructure than almost any other country in the world. That experience matters, but it can only do so much when the virus is caused by a strain that nobody has dealt with for over a decade.
Why is This Ebola 2026 Outbreak Different?
There are four species of orthoebolavirus known to cause disease in humans: Zaire, Sudan, Tai Forest, and Bundibugyo. The Zaire strain - the one behind the devastating 2014–16 West African epidemic that killed more than 11,000 people - now has a licensed vaccine and approved treatments. Bundibugyo does not.
This is only the third documented Bundibugyo outbreak in history. The previous two were in Uganda in 2007 and the DRC in 2012. Because experience with this strain is so limited, the response is considerably harder. Healthcare workers are going in without a vaccine to protect them and there’s no approved treatment. Supportive care - fluids, pain management, treating complications as they arise - is all that is currently available. The case fatality rate for Bundibugyo runs at between 25% and 50%.
The geography makes things worse. The outbreak began in Mongbwalu - a busy mining town in Ituri Province in northeastern DRC, not far from the Ugandan border. By the time it was identified, it had already reached Bunia and Rwampara health zones. An active armed conflict in the same region means response teams cannot always reach affected areas safely, contacts cannot always be traced, and the healthcare infrastructure is already under pressure.
The WHO acted with unusual speed, declaring a PHEIC within 48 hours of laboratory confirmation - and without first convening its standard emergency committee. That has never happened before. This reflects how seriously this outbreak is being taken the WHO.
What Are the Symptoms of Ebola?
Ebola has an incubation period of 2 to 21 days. During this time, a person carries the virus but is not yet contagious and will have no symptoms. Once symptoms develop, they arrive quickly and can deteriorate fast.
Early symptoms typically include:
• Sudden, high fever
• Severe headache
• Muscle and joint pain
• Intense fatigue
• Sore throat
These are followed, often within days, by:
• Vomiting and diarrhoea
• Rash
• Impaired kidney and liver function
• In severe cases - internal and external haemorrhage
People become infectious only once symptoms appear. The later stages of illness carry the highest risk of transmission, as does contact with someone who has died from the disease - which is why dignified but safe burial practices are a critical part of containing any Ebola outbreak.
The early symptoms - fever, fatigue, muscle pain - can easily be mistaken for malaria or a severe flu. In a region where malaria is endemic, that diagnostic confusion is one of the reasons outbreaks often go undetected for weeks. The NHS has further information on Ebola symptoms and what to do if you are concerned.
How Does Ebola Spread?
Ebola mainly spreads through direct contact with the blood or bodily fluids of someone who has symptoms, or through contact with contaminated materials such as bedding or clothing. Many scientists and scientific literature suggest that the infection is not airborne. Given healthcare professionals become infected so easily despite being adequately protected from contact, I believe that air-borne transmission is a possibility and there’s also experimental evidence to suggest this.
The virus is believed to have originated in bats, with transmission to humans occurring through contact with infected animals or their environments. Once in a human population, it spreads person-to-person usually through bodily fluids.
Healthcare workers are at particularly high risk, and the deaths of four healthcare workers in Ituri Province early in this outbreak reflect exactly that. Good infection prevention and control - PPE, isolation of confirmed cases, safe burial protocols - are the cornerstones of containing Ebola in the absence of a vaccine.
Could This Become a Pandemic?
The WHO has explicitly stated that this outbreak does not meet the criteria for a pandemic emergency - the highest level of global alert, introduced after COVID-19.
The spread of Ebola is limited for two reasons:
It spreads mainly through direct contact with bodily fluids from symptomatic individuals.
Infected individuals develop severe symptoms quite quickly which means they are isolated before they get a chance to infect others. (Some sadly die before this)
During the largest Ebola outbreak in history - the 2013–16 West African epidemic with close to 30,000 cases - only a small number of cases were exported to Europe (mostly healthcare workers), without any sustained transmission outside Africa.
The concern with this particular outbreak is regional. Countries sharing borders with the DRC - particularly Uganda and South Sudan - are considered at high risk due to population movement, trade connections, and the geographic proximity of the outbreak’s epicentre to those borders. The spread to Kampala reflects this.
Unlike some other major infectious diseases - as we discussed in our article on why HIV testing and treatment saves lives - there isn’t any approved treatment for the Bundibugyo strain and so prevention here relies entirely on outbreak control measures: case finding, isolation, contact tracing, and safe burial. Effective community engagement and a resilient health infrastructure is therefore vital.
What is the Risk to People in the UK?
The direct risk to the general UK public right now is very low. We at Health Klinix and other leading authorities confirm there’s no current evidence that the outbreak poses a significant risk to the UK public. Ebola causes severe illness and cases in the UK are identified and isolated early before there’s a chance to infect others.
There are, however, people in the UK with family connections to the DRC and Uganda, and there are British aid workers, healthcare volunteers, journalists, and charity workers who travel to and from the region regularly. For those individuals, specific guidance applies.
If you’ve returned from the DRC, Uganda, or South Sudan in the last 21 days and develop a fever, rash, muscle pain, vomiting, or diarrhoea - call NHS 111 immediately. Tell them where you have been. Do not go to A&E unannounced. Healthcare staff need to be prepared before you arrive, both for your safety and theirs.
Healthcare workers travelling to the region as part of the outbreak response must register with the UKHSA Ebola and Marburg Returning Workers Scheme before departure and follow strict infection prevention and control protocols throughout their time there.
Advice for Travellers to Central and East Africa
If you’re planning travel to the DRC, Uganda, or the wider Central and East African region, you’ll need expert pre-travel health advice before you go. The situation is evolving, and the guidance today may look different in two weeks.
Before you travel:
• Check the latest FCDO foreign travel advice for DRC and Uganda - updated regularly and subject to change at short notice.
• Do not travel if you are unwell. Even non-Ebola symptoms can result in quarantine on arrival.
• Be prepared for enhanced screening at airports and border crossings, including temperature checks and health questionnaires.
• There is currently no licensed Ebola vaccine available for travellers to the DRC or Uganda for the Bundibugyo strain.
• Book a travel health consultation with Health Klinix to review all relevant health risks for your specific destination, itinerary, and travel purpose - not just Ebola.
During travel:
• Ensure strict hand hygiene throughout - soap and water where available, alcohol-based sanitiser otherwise.
• Avoid direct contact with anyone who is severely unwell, and avoid all contact with the body or environment of anyone who has died.
• Do not handle or eat bushmeat.
• If you develop symptoms while in the region, isolate yourself and seek care through official medical channels rather than informal healthcare facilities.
A travel health consultation with Health Klinix covers far more than which vaccinations you need. We’ll give you destination-specific advice based on your exact itinerary, the nature of your trip, and your personal health history. If you are travelling to East or Central Africa at the moment, book that consultation before you leave.
Travelling to East or Central Africa? Get Proper Advice Before You Go. The Ebola situation in the DRC and Uganda is moving quickly. The best thing anyone planning travel to the region can do right now is speak to a travel health specialist before departure - not because travel is necessarily off the table, but because the advice you receive needs to be specific to your destination, your itinerary, and your circumstances.

Frequently Asked Questions
Is Ebola contagious before symptoms appear?
No. Someone infected with Ebola is only infectious once symptoms have developed. This is one of the key differences between Ebola and respiratory viruses such as COVID-19, where transmission can occur before symptoms appear.
Is there a vaccine for this strain?
Not yet. Vaccines exist for the Zaire strain of Ebola, but there’s currently no licensed vaccine for Bundibugyo. Research is ongoing, and scientists are investigating whether existing Zaire vaccines may offer any cross-protection, but this has not been confirmed in human trials.
Should I cancel travel to Uganda or the DRC?
That depends on where in those countries you are going and what you will be doing. The WHO has not recommended a blanket travel ban and has advised against border closures. Ituri Province in northeastern DRC should be avoided. Kampala and much of Uganda remain accessible but require vigilance and up-to-date advice. Check the FCDO guidance and speak to a travel health specialist before making any decisions.
How soon can Ebola be detected in a blood test?
Ebola can be detected by PCR testing within a few days of you developing symptoms. Testing during the incubation period, before symptoms appear, is not reliable and is not standard practice. If you have returned from an affected area and develop symptoms, call NHS 111 immediately rather than waiting to seek a test.
What exactly is a PHEIC and how serious is it?
A Public Health Emergency of International Concern is the WHO’s second-highest global alert level. It means the outbreak is considered extraordinary, carries a risk of international spread, and requires a coordinated international response. COVID-19 was declared a PHEIC, as was the 2014–16 West African Ebola epidemic. A PHEIC does not mean a pandemic - the WHO has been explicit about that distinction in this case.
What is the difference between Ebola and other haemorrhagic fevers?
Ebola belongs to the same broad category as Marburg, Lassa fever, and Crimean-Congo haemorrhagic fever. They share the hallmark of severe systemic illness with potential bleeding complications. What distinguishes Ebola is its relatively high fatality rate, its animal reservoir in bats, and the particular logistical challenges of managing it in remote and conflict-affected settings. Anyone travelling to parts of Africa where multiple haemorrhagic fevers circulate should discuss the full range of risks at a travel health consultation before departure.
