EBOLA
Every day, the Busia and Malaba border crossings connect Kenya to Uganda and the wider East African region. Trucks, traders, and travellers move through these corridors, linking local communities to regional markets . These connections are not only essential to the economy, but also disease surveillance posts.
When the word Ebola resurfaces in public health alerts, it brings a familiar anxiety. Years of sensational headlines and documentaries have portrayed it as an airborne particle that causes immediate, uncontrollable bleeding through most body orifices. The reality is medically serious and more complex.
Ebola can cause severe illness and death. Yet, fear and misinformation are often as dangerous as the pathogen itself. When panic takes over, rational precautions collapse, people hide symptoms, avoid hospitals, or distrust health workers making outbreaks harder to control. Understanding the disease means looking at how it spreads, what it does to the body, and what health systems must do to stop it.
For Kenya, these questions are no longer hypothetical.
Ebola in Kenya: What is happening now?
On 6 October 2026, Kenya confirmed its first imported case of Bundibugyo virus disease, a strain of Ebola disease. The patient, a Kenyan citizen who had been living in the Democratic Republic of the Congo (DRC), travelled through Uganda before arriving in Nairobi. The patient died on 5 October, and laboratory testing confirmed the infection.
The initial case was followed by infections among close contacts, including family members and healthcare workers. As of 23 October 2026, Kenya had reported nine confirmed cases, including one death. All nine have been linked to the same cluster.
The response included identifying and monitoring contacts, isolating patients, testing suspected cases, and strengthening surveillance at points of entry. By 22 October, the Ministry of Health said 134 of 135 contacts (over 99%) had been traced and isolated. The first group who completed the required 21-day monitoring period without developing symptoms are expected to leave quarantine on 25 October.
These developments are encouraging, but they do not make the outbreak irrelevant. The appearance of infections among people connected to the initial case illustrates why rapid diagnosis, effective infection prevention, and careful contact tracing are essential.
The outbreak in Kenya is linked to a much larger epidemic of Bundibugyo virus disease in the DRC. The situation shows how an infection originating in one part of the region can cross borders via migration.
Ebola's History
1976
Ebola virus disease was first identified in 1976 during concurrent, independent outbreaks in Nzara (present-day South Sudan) and Yambuku (then Zaire, now the DRC). The pathogen took its name from the nearby Ebola River.
The outbreak in Yambuku exposed a major weakness in healthcare infection control. Reused injection equipment contributed to transmission in a mission hospital, helping the virus spread among patients. The lesson was clear, healthcare facilities can become places of transmission when infection prevention fails and established the need for safe injections, sterilisation, protective equipment, and careful handling of infectious materials.
For years, many outbreaks remained relatively localised but this changed dramatically in West Africa between 2014 and 2016.
2014–2016
The largest Ebola epidemic on record began in Guinea and spread to Liberia and Sierra Leone, causing more than 28,000 reported cases and over 11,000 deaths. Unlike earlier outbreaks concentrated in smaller communities, it reached densely populated cities, including Monrovia and Freetown.
The virus spread alongside fear, misinformation, and weak public health infrastructure. Limited public understanding and distrust of authorities led some people to hide illness, resist contact tracing, or avoid treatment centres. In Liberia, fear and rumours contributed to an attack on a quarantine centre, with people fleeing and potentially exposed individuals dispersing into the community. Weak surveillance, inadequate monitoring across borders, and delays in identifying cases allowed transmission chains to go undetected. Unsafe burial practices, including direct contact with infected bodies, further spread the virus. Together, these failures turned a local outbreak into a regional epidemic.
The epidemic demonstrated that public cooperation is essential: people need to trust health workers enough to report illness, identify contacts, and seek care.
The response accelerated research into vaccines and treatments and changed how the international community approaches Ebola outbreaks.
2018–2020
Between 2018 and 2020, another major outbreak affected eastern DRC, where insecurity and attacks on healthcare facilities complicated the response. Teams had to manage not only the disease but also mistrust and difficulties reaching affected communities.
This outbreak marked important progress in Ebola treatment. The Ervebo(rVSV-ZEBOV) vaccine was deployed on a large scale, and the PALM clinical trial provided strong evidence that specific monoclonal antibody treatments could improve survival among patients with disease caused by the Zaire Ebola virus species.
Uganda, 2022
In September 2022, Uganda declared an outbreak caused by Sudan virus. The outbreak recorded 142 confirmed cases and 55 confirmed deaths.
The available Ebola vaccine and specific antibody treatments were designed for the Zaire Ebola virus species and were not approved as protective measures against Sudan virus. Uganda therefore relied heavily on rapid case detection, isolation, contact tracing, infection prevention, and community engagement.
Why the history matters in 2026
The current outbreak in DRC involves Bundibugyo virus, another Ebola causing virus species. The distinction matters because vaccines and medicines that work against one species don't work against another.
What Ebola does inside the body
Ebola belongs to a group of illnesses classified as viral hemorrhagic fevers (VHFs), a term describing severe syndromes in which viral infection damages blood vessels, makes it hard for blood to clot normally, and prevents the body from controlling its own fluids and blood pressure. The causative agents belong to the family Filoviridae and exhibit a thread like appearance under electron microscope. Several related viral species can cause Ebola disease in humans, with the most common being Zaire, Sudan, and Bundibugyo.
After entering the body, the virus infects cells and uses them to make more copies of itself. It also interferes with the body's early immune defences, allowing the infection to establish itself.
As the virus spreads, the immune response can become severely disrupted. Inflammation, injury to blood vessels, abnormalities in blood clotting, and damage to organs such as the liver may develop. Patients can also lose large amounts of fluid through vomiting and diarrhoea.
These processes can cause blood pressure to fall, reducing the supply of oxygen to vital organs. In severe cases, patients develop shock(circulatory failure) and multiple organ dysfunction.
This explains an important misconception: Ebola is not simply a disease in which people bleed to death. Bleeding can occur(in about a third of the cases), but severe dehydration, shock(circulatory failure), and organ damage are major causes of life threatening illness and consequently death.
Recognising the illness
After exposure, an infected individual enters an incubation period lasting between 2 and 21 days, and most commonly, symptoms present within a week to twelve days. During this incubation window, the person feels completely healthy, carries a low viral load, and crucially cannot transmit the virus to anyone else.
The disease reveals itself in two distinct phases:
The early "dry" phase begins abruptly with a sudden, spiking fever, severe body fatigue, muscle aches, and a headache. This presentation looks identical to malaria, typhoid fever, dengue fever or influenza and hence why it's normally missed at this phase and high transmission to contact persons.
Around the fourth or fifth day, the disease transitions into the severe "wet" phase. Gastrointestinal symptoms: profuse watery diarrhea, persistent vomiting, and severe abdominal cramping. Dehydration sets in rapidly. Patients develop sunken eyes, lethargy(weakness), and weak pulses. A subset of patients may show bruising or bleeding into the stomach and intestines.
How Ebola spreads
Animal to human transmission is where it begins. Fruit bats serve as its primary reservoir, carrying it without falling ill. Spillover into human populations have occurred when hunters handling infected wildlife have contracted the disease.
Once introduced into human communities, transmission occurs through:
Direct contact with infectious bodily fluids: Blood, vomit, stool, and other fluids from a symptomatic infected person can transmit the virus when they contact broken skin or the eyes, nose, or mouth.
Contaminated objects: Bedding, clothing, medical equipment, and needles can pose a risk if contaminated with infectious fluids and handled without appropriate precautions.
Contact with deceased bodies as they carry an exceptionally high viral load. In the past West African epidemic, traditional burial rituals, where family members washed, dressed, and embraced deceased loved ones served as the superspreading event.
Sexual transmission after recovery: Ebola virus can persist in certain body sites, particularly semen, after the person has recovered. Survivors need follow-up testing and safer sex guidance.
Ebola is not ordinarily transmitted through the air in the way COVID-19 is. It does not spread simply because someone shares a room with an infected person. The nature of the contact matters, particularly whether infectious bodily fluids are involved.
Ebola and COVID-19
COVID-19 showed the world how quickly an infectious disease can disrupt healthcare systems, economies, and everyday life. Ebola can also cause serious outbreaks, but the two diseases spread differently.
| Feature | Ebola disease | COVID-19 |
|---|---|---|
| Main route of transmission | Contact with infectious bodily fluids or contaminated objects | Inhalation of airborne respiratory aerosols |
| Transmission before symptoms | People are not considered infectious before Ebola symptoms begin | Transmission can occur before symptoms or from people without symptoms |
| Main prevention priorities | Safe handling of bodily fluids, protective equipment, isolation, contact tracing, and safe burials | Vaccination, ventilation, respiratory precautions, testing, and staying home when infectious |
Treatment, vaccines, and their limitations
The most critical intervention for any patient, regardless of viral species, is early supportive care. Clinicians immediately replace lost fluids and administer medications to curb nausea, pain and antibiotics to counter bacterial infections that seep across damaged gut walls.
For Zaire ebolavirus, there is an available vaccine that's normally administered to immediate contacts of an infected person, along with the contacts of those contacts, to build a ring of immunity that stops community spread. A second vaccine regimen, is used to provide preventive immunity to frontline healthcare workers in at-risk zones.
Therapeutically, there are antibody treatments that neutralize the Zaire virus and significantly reduce mortality when administered early.
However, these drugs do not protect against Sudan ebolavirus or Bundibugyo ebolavirus.
There are currently no licensed vaccines or approved antibody therapies for the Sudan or Bundibugyo species.
What can we do?
A fever in Kenya is almost certainly not Ebola. In most cases, it is caused by everyday illnesses like malaria, a chest infection, or the common flu. Doctors only suspect Ebola when a high fever is paired with specific, direct risks such as traveling to an active outbreak area in the past 21 days or caring for someone severely ill with unexplained fever and bleeding.
If you develop a fever after potential exposure, seek medical attention immediately. When possible, call the health facility ahead of your visit so staff can prepare safely. Always share your complete travel history and any attendance at funeral ceremonies abroad; clear disclosure keeps health workers safe and ensures you receive the correct treatment quickly.
To help protect yourself and your community:
- Avoid high risk contact: Do not touch the body fluids of anyone who is ill, and avoid handling or eating wild animals found dead in forests, especially bats and primates.
- Follow health guidance: Stick strictly to official quarantine or monitoring instructions if you are identified as a contact.
- Rely on verified facts: Ignore social media rumors or unproven remedies like saltwater drinks.
- Reject stigma: Treat patients, affected families, and survivors with dignity. Blaming or isolating people forces them to hide their symptoms, making infections far harder to stop.
How we can win against Ebola.
History has already shown us what happens when an Ebola outbreak gets out of hand, and we cannot afford to learn that painful lesson the hard way. Other nations paid a devastating price when fear took over, rumours spread faster than the truth, and small gaps in prevention opened the door to widespread loss. We have the chance to protect one another, but emergency plans on MOH memos won't do it alone, our safety comes down to daily, collective action.
Keep up with simple, lifesaving hygiene like washing your hands regularly with soap and clean water, avoiding unsafe contact with sick individuals or unknown wildlife, and looking out for your neighbours.
Most importantly, if you ever feel unwell after travelling to an affected area or being around someone with compatible symptoms, do not hide it or try home remedies. Call ahead, go straight to a hospital, and be completely honest about your history. Taking care of your health with prompt, transparent medical care is the greatest act of protection you can offer your family and community.
