Ebola Outbreak in DR Congo Expands Rapidly as Cases Reach Nearly 5,800

Kinshasa, The Democratic Republic of Congo is confronting a rapidly expanding Ebola outbreak, with health authorities reporting 5,794 confirmed cases and 2,786 deaths as of August 26.

The outbreak, caused by the relatively rare Bundibugyo virus, has now reached 60 health zones across six provinces, according to the World Health Organization. The number of affected health zones has increased from 54 in the previous WHO update, demonstrating how quickly transmission is spreading geographically.

WHO has maintained the outbreak’s status as a Public Health Emergency of International Concern (PHEIC). The agency says the current situation remains particularly serious because transmission is continuing and health systems in affected areas face major operational challenges.

A Record Ebola Outbreak for Congo

The current epidemic has become the largest Ebola outbreak ever recorded in the Democratic Republic of Congo, surpassing the country’s previous major outbreak of 2018–2020.

The outbreak initially emerged in the Mongbwalu health zone of Ituri Province before spreading into additional provinces.

The six provinces now reporting cases are Ituri, North Kivu, South Kivu, Haut-Uélé, Bas-Uélé and Tshopo.

The expansion has made disease surveillance and contact tracing increasingly difficult.

Thousands of Families Have Been Affected

Behind the rapidly increasing statistics are thousands of patients and families dealing with the consequences of a highly dangerous infectious disease.

WHO reports a crude case-fatality ratio of approximately 48.1% among confirmed cases.

However, the organisation cautions that the figures are influenced by several factors, including delays in detecting infections, laboratory confirmation and the reconciliation of previously collected data.

At least 1,293 patients had recovered according to the latest WHO update, demonstrating that survival is possible when patients receive appropriate medical care.

Ituri Remains the Main Epicentre

The province of Ituri continues to account for the largest share of infections.

According to the latest compiled figures, Ituri has recorded more than 4,800 confirmed cases since the outbreak began.

North Kivu is the second most affected province, with hundreds of confirmed cases and a particularly high reported fatality ratio.

The continuing spread into new health zones means that response teams must constantly establish surveillance and treatment capabilities in additional locations.

Why Containing the Virus Is So Difficult

The outbreak is occurring in a region already affected by insecurity, displacement and limited access to healthcare.

Armed conflict and population movements can make it difficult for medical teams to reach communities, identify contacts and maintain consistent monitoring.

Healthcare workers also face the risk of infection while treating patients.

In some affected communities, mistrust and misinformation can further complicate efforts to persuade people to report symptoms, accept testing or cooperate with contact tracing.

Contact Tracing Is Under Pressure

Contact tracing is one of the most important tools for stopping Ebola transmission.

Health workers identify people who may have been exposed to an infected person and monitor them for symptoms.

As the outbreak grows, however, the number of people requiring follow-up increases rapidly.

On August 26, more than 26,800 contacts were identified as requiring monitoring, with approximately 82% under follow-up, according to WHO-linked reporting.

Maintaining such a large surveillance network requires significant numbers of trained personnel, transportation, communications equipment and laboratory capacity.

Vaccination Campaign Begins

Authorities have begun using the Ervebo Ebola vaccine to protect frontline and healthcare workers.

The vaccine is licensed for protection against Zaire ebolavirus, not specifically the Bundibugyo virus responsible for the current outbreak. Nevertheless, health authorities are studying whether it can provide protection against this strain.

More than 50,000 doses have reached Congo, while WHO has authorised additional doses for use in the response and clinical research.

A portion of the vaccine supply is being used in clinical trials designed to determine its effectiveness against Bundibugyo virus.

No Approved Bundibugyo-Specific Vaccine Yet

One of the biggest scientific difficulties is that there is currently no approved vaccine specifically targeting Bundibugyo virus, and no approved treatment specifically designed for the virus.

WHO says clinical trials are underway to evaluate possible vaccines and therapies.

Researchers are studying several potential approaches, including experimental vaccines and antiviral or antibody-based treatments.

This makes the current response heavily dependent on traditional Ebola-control measures such as early detection, isolation, supportive care, contact tracing, infection prevention and safe burials.

Clinical Trials Move Quickly

Scientists are racing to evaluate potential treatments while transmission remains active.

One major trial is examining experimental therapies including the monoclonal antibody MBP134 and the antiviral drug remdesivir, both separately and in combination.

Another research programme is investigating obeldesivir as a possible post-exposure treatment for people at high risk of developing disease.

The speed at which researchers have organised these trials reflects the urgency created by the unprecedented scale of the outbreak.

Healthcare Workers Face Their Own Crisis

The medical response has also been complicated by difficulties affecting healthcare workers.

Reports indicate that some frontline personnel have experienced delayed payments, exhaustion and frustration, while insecurity has increased the dangers associated with working in affected communities.

A weakened healthcare workforce can make outbreak control considerably harder.

Doctors, nurses, laboratory workers, ambulance teams, burial teams and community health workers all play critical roles in preventing transmission.

Uganda Declares Its Outbreak Over

There is some encouraging news elsewhere in the region.

Uganda officially ended its Bundibugyo Ebola outbreak after completing the required period without new confirmed cases. WHO subsequently confirmed the end of the Ugandan outbreak.

Uganda recorded 20 confirmed cases and two deaths during its outbreak.

However, WHO continues to regard cross-border transmission as a risk because people and goods move regularly between Uganda and affected parts of Congo.

International Spread Remains a Concern

The geographical expansion of the Congo outbreak has raised concerns about transmission across national borders.

WHO has recommended stronger surveillance at land crossings and increased coordination among neighbouring countries.

Countries bordering Congo and other countries considered at elevated regional risk have been advised to maintain preparedness and strengthen their ability to rapidly identify suspected cases.

At the same time, WHO does not recommend blanket travel or trade restrictions against affected countries.

International Response Needs More Resources

The scale of the epidemic is placing considerable demands on Congo’s health system and international partners.

Response organisations require funding for laboratories, treatment centres, protective equipment, transportation, vaccination research and community engagement.

UN Secretary-General António Guterres has warned that the outbreak is expanding faster than containment efforts and has urged the international community to increase its support.

Community Trust Is Critical

Medical interventions alone cannot stop an Ebola outbreak.

People must be willing to report symptoms, allow health workers to investigate possible exposure and cooperate with infection-control measures.

WHO has therefore placed increased emphasis on working with local leaders, religious figures, traditional healers, survivors and community networks.

Safe and dignified burials are another important component because direct contact with the bodies of Ebola victims can expose relatives and funeral workers to infection.

The Road Ahead

The latest numbers demonstrate that Congo’s Ebola crisis remains extremely serious.

With 5,794 confirmed cases, 2,786 deaths and transmission across 60 health zones, the outbreak has reached an unprecedented scale for the country.

There are encouraging developments, including expanded testing, vaccination of frontline workers, new treatment trials and improved surveillance in some areas.

But continued transmission, insecurity, population displacement and limited resources remain major obstacles.

The coming weeks will be crucial. Health authorities and international partners must expand case detection, treatment, contact tracing and community engagement while researchers work to determine whether existing vaccines and experimental medicines can help control Bundibugyo virus.

For now, the central objective is clear: slow transmission, save patients’ lives and prevent the outbreak from spreading beyond the communities already facing its devastating effects.
