The initial alert reached the WHO on May 5, 2026, after an unknown disease with high mortality was reported in the Mongbwalu health zone in Ituri province. The investigation confirmed the disease to be caused by the Bundibugyo virus on May 15 after analyses conducted by the National Institute of Biomedical Research in Kinshasa.

The DRC officially declared its 17th Ebola outbreak on the same day. The Rwampara Mongbwalu and Bunia areas became the focus of the health response, while unusual clusters of community deaths were also assessed in Ituri and North Kivu. The presence of cases in Kampala raised the regional risk because international spread had already been documented.

Two confirmed cases in Uganda had a history of travel from the DRC, and Ituri's proximity to Uganda and South Sudan increased the urgency of cross-border coordination. The Associated Press reported on May 18 that the DRC was preparing to open three treatment centers in Ituri.

The agency reported more than 390 suspected cases and 105 deaths in the country attributed to the local health cluster and still subject to laboratory validation. The opening of these units became relevant because local hospitals were facing increasing pressure and because confirmation of cases requires rapid isolation.

In Ebola outbreaks, the time between the first community alert and the organized response influences the number of exposed contacts and the population's confidence in health teams.

Therefore, the national declaration was accompanied by requests for technical support, medical supplies, and enhanced surveillance. The initial response sought to connect laboratories, provincial authorities, humanitarian partners, and field teams.

Ebola is transmitted through direct contact with blood, secretions, organs, or other bodily fluids of infected individuals. The disease can also be spread through contaminated materials and unprotected funeral practices, especially when family members touch the body of a person who died during the infectious phase of the disease.

The initial symptoms can be confused with other common febrile illnesses such as malaria. The WHO describes fever, fatigue, muscle aches, headache, and sore throat as frequent early signs before progression to vomiting, diarrhea, abdominal pain, organ dysfunction, and hemorrhagic manifestations in some cases.

The Bundibugyo species had already been detected in Uganda in 2007-2008 and in the DRC in 2012. The WHO estimates that the lethality observed in these outbreaks ranged between approximately 30% and 50%. Doctors Without Borders estimates between 25% and 40% for this strain.

The main difficulty lies in the absence of a licensed vaccine and specific treatment against Bundibugyo. Medical care focuses on clinical support, hydration, symptom management, and prevention of new transmission chains. Laboratory confirmation by PCR becomes crucial because clinical diagnosis alone can delay the response.

The absence of approved immunization alters the operational logic. In epidemics caused by the Zaire strain, ring vaccination campaigns helped protect exposed contacts and professionals. In Bundibugyo, this barrier is not available, and each suspected case requires isolation, clinical evaluation, and laboratory confirmation more quickly.

The importance of community communication is also growing because fear can keep families away from health centers. When the population understands how transmission occurs, it becomes more likely that they will report symptoms, accept safe burials, and cooperate with the tracing of exposed individuals during the incubation period.

The WHO justified the international emergency by citing the extraordinary nature of the Ebola outbreak, the threat to other states, and the need for international coordination. The organization highlighted insecurity, population mobility, the humanitarian crisis, and the existence of many informal health services as factors that could favor its spread.

Ituri is a province marked by population displacement, mining activity, armed violence, and difficult access to healthcare. These conditions complicate contact tracing, the deployment of medical teams, the protection of professionals, and communication with communities already living under strong social and economic pressure.

The Africa CDC reported that it was supporting the authorities of the DRC, Uganda, and South Sudan in regional coordination. The institution highlighted cross-border surveillance, alert management, laboratory diagnosis, infection prevention, risk communication, safe burials, and resource mobilization as priorities.

Neighboring countries were urged to strengthen preparedness without resorting to measures that indiscriminately hinder the movement of people and goods. The WHO recommends health screenings at points of entry, immediate notification of suspected cases, team formation, and work with local religious and traditional leaders.

Geography increases the challenge because the region's borders are crossed by family trade, work-related travel, and the search for medical care. An infected person may travel before recognizing symptoms and expose family members, passengers, or healthcare professionals if well-coordinated alert systems are not in place.

For this reason, regional preparedness must combine surveillance at points of entry, laboratories capable of confirming samples, safe transport of patients, and clear information in local languages.

Doctors Without Borders announced the preparation of a large-scale response in Ituri after receiving alerts about an increase in deaths suspected to be from viral hemorrhagic fever in Mongbwalu. The organization stated that teams were already assessing medical needs and that more professionals, logistical material, and essential supplies were being mobilized.

The number of cases and deaths observed in such a short period, combined with the spread across multiple health zones and now beyond the border, was described by Trish Newport of Doctors Without Borders as extremely worrying.

The DRC announced the opening of three treatment centers in Ituri in an attempt to relieve already strained hospitals. The WHO sent specialists and emergency medical supplies to Bunia while other humanitarian organizations prepared teams to support isolation, triage, surveillance, and infection prevention.

Protecting healthcare workers has become a priority in the Ebola response. The WHO reported deaths among healthcare workers early in the alert and noted that transmission within healthcare facilities can accelerate outbreaks when there is a lack of equipment, safe circuits, training, and rapid diagnosis. The response must also preserve access to essential services for uninfected patients.

Treatment centers must separate suspected, confirmed, and ruled-out cases to reduce infections within the units. This organization requires tents or dedicated wards, clean water, personal protective equipment, safe waste disposal, and trained personnel to remove gloves, masks, and gowns without contamination.

Psychosocial support is also necessary because isolation frightens families and patients. The medical team must explain procedures, allow safe contact with relatives, and ensure food, hydration, pain management, and monitoring of other common illnesses in the region throughout the entire safe clinical stay.

Public communication is a central part of the Ebola response. Authorities need to explain symptoms, transmission routes, and protective measures without fueling fear or stigma. Communities should know that an infected person usually transmits the virus after the onset of symptoms and that seeking early care increases the chance of survival.

The risk to countries far from the affected region remains low, but international surveillance has increased. The European Centre for Disease Prevention and Control stated that the probability of infection for people in the European Union and the European Economic Area is currently very low, although the situation continues to evolve.

The African response will depend on how quickly cases are found, isolated, and treated. It will also depend on the trust of communities because safe burials, contact tracing, and communication about symptoms require local cooperation. Without this cooperation, transmission chains can remain hidden for crucial days.

An international emergency does not mean the world is facing a pandemic. It means the outbreak requires shared resources, information, and coordinated action before the disease finds new routes. The DRC's accumulated experience with previous outbreaks is important, but Bundibugyo presents its own difficulties due to the lack of approved vaccines and treatments.

Conflicting messages can hinder the response when rumors attribute the illness to punishment, witchcraft, or external interests. Therefore, local religious leaders, traditional teachers, and community agents should receive simple and verifiable information to guide families on symptoms, isolation, safe transportation, and contactless burials.

The information should also avoid blaming survivor travelers or healthcare professionals. Combating stigma facilitates the reporting of symptoms, keeps contacts under observation, and allows recovered individuals to return to their communities with social protection.

The Ebola outbreak in the DRC and Uganda exposes the fragility of the areas where the disease circulates amidst conflict, displacement, and limited health services. The WHO declaration seeks to accelerate resources, align responses, and prevent transmission from gaining greater regional reach.

The immediate priority is simple in formulation and complex in execution: detect cases, isolate patients, protect professionals, monitor contacts, ensure safe burials, and keep communities informed.

The lack of an approved vaccine against Bundibugyo makes each delay more dangerous. The region has experienced institutions and prepared partners, but success will depend on the speed of public confidence and coordination between neighboring countries.
