Ebola resurges in Eastern DRC as conflict, mistrust hinder response

The Democratic Republic of Congo is once again battling an Ebola outbreak, but this time health authorities are facing a particularly difficult challenge.

The virus is spreading through the country's conflict-ridden east, where insecurity, population displacement, weak healthcare infrastructure and the absence of an approved vaccine have complicated efforts to contain the disease.

Ebola, a highly infectious virus transmitted through close contact with infected individuals and bodily fluids, can cause severe hemorrhagic fever and has claimed more than 15,000 lives across Africa over the past five decades.

Experts warn that the latest outbreak could become one of the region's most difficult public health emergencies in recent years.

A silent spread before detection

Congo officially declared its 17th Ebola outbreak on May 15, but evidence suggests the virus had been circulating for weeks, if not months, before authorities identified it.

Warning signs first emerged in early May when the World Health Organization received reports of a mysterious illness in the mining town of Mongbwalu.

Within days, four healthcare workers had died, raising concerns about a potentially serious outbreak.

Residents in Ituri province, the epicenter of the crisis, told reporters that unexplained deaths had been occurring since March. Rumors of a mysterious disease spread through communities long before medical officials confirmed Ebola as the cause.

Early detection efforts were hindered by the disease's symptoms, which closely resemble malaria, typhoid fever and yellow fever during its initial stages.

Several patients were initially misdiagnosed, allowing the virus to continue spreading unnoticed.

Laboratory challenges further delayed identification.

Testing facilities in Bunia, the provincial capital, were equipped primarily to detect the more common Zaire strain of Ebola and initially failed to identify the Bundibugyo strain responsible for the current outbreak.

By the time officials confirmed the disease, 246 suspected cases and 80 deaths had already been recorded across Ituri.

Concerns quickly extended beyond Congo's borders. On the same day the outbreak was declared, neighboring Uganda reported the death of a Congolese traveler linked to the outbreak, heightening fears of regional transmission.

Although Uganda has since confirmed only a limited number of cases, authorities moved swiftly to close border crossings and strengthen surveillance measures.

The rapid emergence of infections prompted the World Health Organization to declare a global health emergency, warning that the outbreak could persist for months if not aggressively contained. The Africa Centres for Disease Control and Prevention has also cautioned that as many as 10 countries could face elevated risk because of regional movement and trade routes.

Vaccine-free strain

One of the most troubling aspects of the outbreak is the strain involved.

The Bundibugyo strain currently circulating has no approved vaccine and no specific treatment, leaving health workers without one of the most effective tools used during previous Ebola outbreaks.

Vaccines developed during major outbreaks between 2018 and 2019 successfully targeted the Zaire strain but offer no protection against Bundibugyo.

As a result, medical teams have been forced to rely on traditional containment strategies, including isolating infected patients, tracing contacts and educating communities. These methods can be effective but require rapid action, public cooperation and access to affected areas, all of which remain difficult in eastern Congo.

The disease itself presents additional obstacles. Early symptoms often resemble common tropical illnesses, delaying diagnosis and increasing the likelihood of further transmission.

Veteran Congolese virologist Jean-Jacques Muyembe, one of the scientists involved in the discovery of Ebola in 1976, acknowledged that the unusual presentation initially created confusion among medical professionals.

There is some hope on the horizon. Africa CDC says a vaccine specifically targeting the Bundibugyo strain could be available before the end of the year, with clinical trials under consideration. Until then, however, health workers must rely on conventional outbreak-control measures.

Violence and instability

The outbreak is unfolding in one of the most unstable regions of the country.

Ituri has endured years of violence involving local militias and extremist groups, including factions linked to the Islamic State. Frequent attacks have displaced thousands of people, forcing families into crowded camps where infectious diseases can spread rapidly.

The insecurity has significantly hampered medical operations. Health workers often struggle to reach remote communities, while humanitarian organizations face logistical and security challenges when delivering aid.
