Ebola (Ebola virus disease, or EVD) is a rare but severe illness caused by a group of viruses called orthoebolaviruses, which trigger high fever, extreme fatigue, and — in advanced cases — dangerous bleeding and organ failure. It spreads through direct contact with the blood or body fluids of an infected person or animal, not through the air. Caught early, Ebola is survivable with the right supportive care, and for one strain (Zaire virus) two FDA-approved treatments and a vaccine now exist. Below, we break down the causes, the full symptom timeline, current treatment options, and what’s happening with the active 2026 outbreak in Central Africa.
What Is Ebola?
Ebola disease is caused by orthoebolaviruses (formerly called ebolaviruses), a family of viruses first identified in 1976 near the Ebola River in the Democratic Republic of the Congo (DRC). According to the CDC, these viruses are found primarily in sub-Saharan Africa and can cause mortality rates as high as 80–90% in the worst outbreaks, though the actual fatality rate varies significantly by virus species and access to care.
There are four orthoebolavirus species known to cause illness in people:
- Zaire virus — causes Ebola virus disease (EVD), the most common and historically most fatal strain
- Sudan virus — causes Sudan virus disease (SVD)
- Bundibugyo virus — causes Bundibugyo virus disease (BVD), the strain behind the 2026 outbreak
- Taï Forest virus — the rarest strain, with only one known human case
The Current Ebola Outbreak (2026 Update)
As of this writing, Central Africa is in the middle of an active Ebola outbreak caused by the Bundibugyo virus — the 17th recorded Ebola outbreak in the DRC since 1976, and now considered the third-largest Ebola outbreak on record according to the Council on Foreign Relations. The World Health Organization declared it a Public Health Emergency of International Concern (PHEIC) on May 17, 2026.
| Country | Confirmed Cases | Deaths | Recovered |
|---|---|---|---|
| DRC | 2,124 | 828 | 390 |
| Uganda | 20 | 2 | 17 |
Source: European Centre for Disease Prevention and Control, data reported July 16, 2026. Ituri Province remains the epicenter, accounting for the large majority of cases. Uganda’s last confirmed case was reported June 21, and the country has since begun the 42-day countdown toward declaring its outbreak over.
Unlike previous outbreaks, this one is caused by the Bundibugyo strain, for which no vaccine or antiviral treatment is currently approved — the existing Ebola vaccine and drugs were developed for the Zaire strain only. The response has also been complicated by active armed conflict and displacement in eastern DRC, which has hampered contact tracing and treatment access.
“Ebola caused by the Bundibugyo virus can be survived with good medical care… seeking care early makes a real difference.”
— Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, May 30, 2026
What Causes Ebola? (How Do You Get It?)
How Ebola Spreads
Ebola is not airborne and does not spread the way flu or COVID-19 does — you can’t catch it from being near an infected person. Per the CDC, transmission requires direct contact with:
- Blood, vomit, urine, feces, saliva, sweat, breast milk, or semen from an infected person
- Contaminated surfaces, clothing, bedding, needles, or medical equipment
- The body of someone who has died from Ebola (a major risk during traditional burial practices)
- Infected animals, especially fruit bats and non-human primates, or their raw meat
A person only becomes contagious once they start showing symptoms — not during the incubation period.
Types of Ebola Virus at a Glance
| Virus Species | Disease | Approx. Fatality Rate | Approved Treatment? |
|---|---|---|---|
| Zaire virus | Ebola virus disease (EVD) | ~50% historically (up to 90%) | Yes — Inmazeb, Ebanga, ERVEBO vaccine |
| Sudan virus | Sudan virus disease | ~50% | No |
| Bundibugyo virus | Bundibugyo virus disease | 25%–50% | No (trials underway) |
| Taï Forest virus | Taï Forest virus disease | Extremely rare; limited data | No |
Ebola Symptoms: The Full Timeline
Symptoms typically begin 8 to 10 days after exposure, though the incubation period can range from 2 to 21 days, per the CDC. Ebola symptoms usually progress in two phases:
Early “Dry” Symptoms
- Sudden fever
- Severe fatigue
- Muscle and joint pain
- Headache
- Sore throat
Later “Wet” Symptoms
As the illness progresses, patients often develop:
- Vomiting and diarrhea
- Rash
- Impaired kidney and liver function
- Unexplained internal or external bleeding
- In severe cases, multi-organ failure
Because early symptoms overlap with malaria, typhoid, and the flu, Ebola is easy to miss without a known exposure history — which is exactly why lab testing matters in an active outbreak area.
How Is Ebola Diagnosed?
Healthcare providers confirm Ebola using a PCR (polymerase chain reaction) blood test, which detects viral genetic material. Antibody testing can also show whether someone was previously infected. Anyone being tested is isolated from other patients until results come back, since even a suspected case requires strict infection control.
Ebola Treatment Options
FDA-Approved Treatments (Zaire Virus Only)
Two monoclonal antibody therapies are FDA-approved, but only for Ebola disease caused by the Zaire species:
- Inmazeb™ — a cocktail of three monoclonal antibodies
- Ebanga™ — a single monoclonal antibody
Neither drug is approved for Sudan, Bundibugyo, or Taï Forest virus, which is a key reason the 2026 outbreak has been so difficult to treat. Antiviral candidates including remdesivir and the monoclonal antibodies MBP-134 and maftivimab are currently in clinical trials for the Bundibugyo strain.
Supportive Care
Regardless of strain, early supportive care significantly improves survival odds. This includes:
- IV fluids and electrolyte (body salt) replacement
- Medications to stabilize blood pressure
- Treatment for nausea, vomiting, and diarrhea
- Pain and fever management
- Treating any secondary infections
Can Ebola Be Prevented?
The FDA-approved vaccine ERVEBO® protects against the Zaire strain only and is recommended for adults 18+ at risk of exposure. It is not effective enough against the Bundibugyo strain to be recommended in the current outbreak — the WHO advised against using it there in May 2026 due to insufficient evidence of cross-protection.
If you’re in or traveling to an area with an active outbreak, the CDC recommends:
- Avoiding contact with blood and body fluids of sick individuals
- Avoiding contact with bats, primates, and bushmeat
- Not attending funerals or burial rituals that involve touching the body
- Wearing personal protective equipment around anyone who may be infected
- Monitoring your health for 21 days after possible exposure and seeking care immediately if symptoms appear
Ebola Survival Rate: What’s the Outlook?
Survival depends heavily on the virus species, how quickly treatment begins, and access to quality healthcare. Historical Ebola outbreaks have had fatality rates ranging from roughly 25% to 90%. In the current Bundibugyo outbreak, hundreds of patients have already recovered in both DRC and Uganda — evidence that early treatment-seeking behavior directly improves outcomes, even without a targeted antiviral.
Frequently Asked Questions About Ebola
What is Ebola virus disease?
Ebola virus disease (EVD) is a severe, often fatal illness caused by orthoebolaviruses. It causes fever, fatigue, and body aches early on, potentially progressing to vomiting, diarrhea, and dangerous bleeding in later stages.
How do you catch Ebola?
You catch Ebola through direct contact with the blood or body fluids of an infected person or animal, or by touching contaminated surfaces, clothing, or medical equipment. It does not spread through casual contact or air.
What are the first signs of Ebola?
The earliest signs are sudden fever, severe fatigue, muscle and joint pain, headache, and sore throat, typically appearing 8 to 10 days after exposure.
Is there a cure for Ebola?
There is no universal cure. Two FDA-approved antibody treatments, Inmazeb and Ebanga, work specifically against the Zaire strain. Other strains, including the Bundibugyo virus behind the 2026 outbreak, currently have no approved treatment and rely on supportive care.
Is Ebola airborne?
No. Ebola does not spread through the air like flu or COVID-19. You cannot get it from being near an infected person without direct contact with their body fluids.
What is the current Ebola outbreak in 2026?
An outbreak of Bundibugyo virus disease has been affecting eastern DRC and Uganda since May 2026. As of mid-July 2026, DRC has reported over 2,100 confirmed cases and more than 800 deaths, with Uganda’s outbreak nearing containment.
How deadly is Ebola?
Fatality rates vary by strain, ranging from roughly 25% to as high as 90% in the worst historical outbreaks. Early treatment and access to supportive care significantly improve survival odds.
