DR Congo Ebola Outbreak Now Second-Largest Ever Recorded: What You Need to Know

The Ebola outbreak in the Democratic Republic of the Congo (DRC) has become the second-largest Ebola outbreak ever recorded, with health officials warning that it is spreading faster than any Ebola epidemic in history. As of 31 July 2026, more than 3,500 people have been infected with the virus, and the outbreak shows no signs of slowing. Here is what you need to know about the 2026 Ebola outbreak in DR Congo, why it is different from previous epidemics, and what is being done to contain it.

Key Facts About the 2026 DR Congo Ebola Outbreak

• 3,532 confirmed cases reported by the DRC Ministry of Public Health as of 31 July 2026
• 1,556 deaths, giving a case fatality rate of 44.1 percent
• Only the 2014–2016 West Africa Ebola outbreak was larger, with 28,616 cases and 11,310 deaths
• The outbreak is caused by the Bundibugyo strain of the Ebola virus, which has no approved vaccine or treatment
• The virus has spread across five provinces: Haut-Uele, Ituri, North Kivu, South Kivu and Tshopo
• Around 807 patients remain in isolation or hospital care, while 626 have recovered

Why This Outbreak Is Different

The current epidemic began less than three months ago, yet it has already surpassed the DRC’s previous record outbreak of 2018–2020, which recorded roughly 3,470 cases. According to the Africa Centres for Disease Control and Prevention (Africa CDC), the disease has killed five times as many people as previous outbreaks had by the same stage.

“It’s the fastest spreading Ebola epidemic that we have ever seen,” said Carl Skau, acting head of the United Nations World Food Programme. “The world needs to pay much more attention.”

One of the most worrying features of this outbreak is the virus strain involved. The Bundibugyo virus is a rare species of Ebola that has only caused a handful of small outbreaks since it was first identified in Uganda in 2007. Unlike the more common Zaire strain of Ebola, which has two licensed vaccines (Ervebo and Zabdeno/Mvabea) and effective monoclonal antibody treatments, there is no approved vaccine or specific antiviral treatment for Bundibugyo virus disease. Candidate vaccines and therapies are still in development.

Where the Outbreak Is Spreading

The outbreak is concentrated in eastern DRC, a region where dozens of armed groups operate and where attacks on health facilities have become a serious problem. Medical personnel are also battling significant foreign aid cuts that have stretched resources to breaking point.

Health workers at Ebola treatment centres have staged strikes over unpaid wages and unsafe conditions, further slowing the response. A lack of trust in authorities has also driven many families to seek care from traditional healers rather than treatment centres, allowing chains of transmission to continue undetected in the community.

The World Health Organization has warned that the true scale of the outbreak could be up to four times higher than official figures suggest, because many cases are never reported or tested. The Africa CDC has estimated that US$1.4 billion will be needed to contain the outbreak — three times its earlier estimate.

How Ebola Spreads

Ebola is not an airborne virus. It spreads through direct contact with the blood or body fluids of a person who is sick with or has died from the disease, including vomit, diarrhoea, urine, sweat and breast milk. It can also spread through contaminated objects and surfaces, and through unsafe burial practices that involve touching the body of someone who died from Ebola.

People cannot transmit the virus before they develop symptoms, and they remain infectious while the virus is present in their blood. Health workers are at particular risk, which is why strict infection prevention and control measures are essential in every treatment facility.

Symptoms to Know

The incubation period — the time between infection and the appearance of symptoms — ranges from 2 to 21 days. Symptoms can appear suddenly and include:

• Fever, fatigue and general malaise
• Muscle pain, headache and sore throat
• Vomiting and diarrhoea
• Abdominal pain and skin rash
• Impaired kidney and liver function
• In severe cases, internal and external bleeding — although bleeding is less common than many people assume and usually occurs later in the illness

Because early Ebola symptoms are similar to malaria, typhoid and other common infections, laboratory testing with RT-PCR is essential to confirm a diagnosis.

Treatment and Prevention

For patients infected with the Bundibugyo strain, the mainstay of care is optimised supportive treatment: aggressive rehydration, management of pain and co-infections such as malaria, and close monitoring. Early treatment seeking dramatically improves survival.

Prevention relies on the full outbreak-control package: community engagement, surveillance and contact tracing, laboratory services, infection prevention and control, safe and dignified burials, and social mobilisation. Public health experts stress that raising awareness of risk factors — such as avoiding contact with infected animals, not consuming bushmeat, and isolating anyone with symptoms — is one of the most effective ways to slow transmission.

Why the World Should Pay Attention

Ebola outbreaks are no longer a distant problem. International air travel means an infected person can move from a rural village in eastern Congo to a major global city within 24 hours. Several countries have already introduced screening measures at airports for travellers arriving from affected regions.

The outbreak also highlights a broader lesson: when global health systems are underfunded and health workers are unprotected, deadly viruses gain the upper hand. The WHO, Africa CDC and humanitarian agencies are calling for urgent international support — both funding and personnel — before the outbreak becomes even harder to control.

Frequently Asked Questions

What is the Ebola virus?

Ebola disease is a severe, often fatal illness in humans caused by viruses in the Orthoebolavirus genus. Three species cause large outbreaks: Ebola virus, Sudan virus and Bundibugyo virus. The average case fatality rate is around 50 percent, but it has ranged from 25 to 90 percent in past outbreaks.

Is the current outbreak in DR Congo caused by a new strain?

No — the outbreak is caused by the Bundibugyo virus, a known but rare species of Ebola first identified in Uganda in 2007. What is new is the scale and speed of this outbreak, which is the largest Bundibugyo outbreak ever recorded.

Is there a vaccine for this Ebola outbreak?

No. Licensed Ebola vaccines (Ervebo and Zabdeno/Mvabea) protect only against the Zaire strain of Ebola virus. No approved vaccine exists for the Bundibugyo strain, although candidate vaccines are in development.

How is Ebola treated?

There is no cure for Ebola, but early intensive supportive care — including rehydration and treatment of symptoms — significantly improves survival. For the Zaire strain, monoclonal antibody treatments such as ansuvimab and REGN-EB3 are available; for Bundibugyo virus disease, no approved specific treatment exists yet.

Should travellers be worried?

Travellers to the affected provinces of eastern DRC should follow public health guidance, avoid contact with sick people and their body fluids, avoid handling dead animals or bushmeat, and practise strict hand hygiene. Anyone developing fever or Ebola-like symptoms within 21 days of returning from an affected area should seek medical care immediately and disclose their travel history.

Can Ebola spread through the air?

No. Ebola spreads through direct contact with infected body fluids or contaminated surfaces, not through the air like influenza or COVID-19.
