The warning comes as health workers involved in the response strike over unpaid wages and the outbreak continues to grow in a conflict-affected region. Congo’s Ministry of Health had recorded 3,874 confirmed cases and 1,751 deaths as of Aug. 3, according to figures cited by The Associated Press.

The outbreak is concentrated in eastern Congo, particularly Ituri Province and the city of Bunia. It is described as the fastest-growing Ebola outbreak in the world, with the number of cases increasing faster than health officials can track and respond to them.

A response under pressure

The strike has added a labor dispute to an already difficult public-health emergency. Health workers have stopped working over unpaid wages during the response, raising concern about the ability of local and international teams to maintain the services needed to identify cases and limit transmission.

More than 100 health-care workers have been infected since the outbreak began, according to WHO reporting cited by AP. Those infections underscore the risks facing personnel working in treatment and disease-control operations and add pressure to a response that depends on trained staff in affected communities.

The outbreak’s concentration in eastern Congo is significant because the region is affected by conflict and has weakened health services. Those conditions can make it harder to detect infections, provide treatment and contain the disease, especially when health workers are absent from their posts or are not being paid.

Rising toll in eastern Congo

The case and death totals reported by Congo’s health ministry show the scale of the emergency. The 3,874 confirmed cases and 1,751 deaths were recorded as of Aug. 3, two days before Tedros’s warning. The figures may change as health officials identify additional cases and update the count.

The death toll had already passed 1,700 in earlier reporting, while the outbreak was described as moving faster than health officials could track. The latest figures indicate that the outbreak has continued to impose a heavy toll in Ituri Province and around Bunia.

WHO’s warning does not describe the outbreak as a pandemic or establish transmission beyond the affected area. Instead, it highlights a growing emergency in eastern Congo where disease control is being strained by the speed of the outbreak, risks to health workers and interruptions caused by the wage dispute.

Wider emergency pressures

The Ebola response is unfolding amid broader constraints on international health operations. In a 2026 emergency appeal, WHO said its work covered 36 emergencies worldwide and that health-emergency capacity was being limited by conflict, disease outbreaks and reduced humanitarian funding.

Those pressures matter for eastern Congo because containing Ebola requires sustained attention and functioning health services. The immediate challenge is to keep response operations running while health authorities confront the expanding caseload and protect workers who are themselves at risk of infection.

Tedros’s visit brought the warning directly to the country as Congo’s health ministry continued to report new totals. The next known measure of the outbreak will be whether response teams can slow the growth in cases and restore consistent participation by health workers. No outcome from the strike or a timetable for resolving the unpaid-wage dispute was identified in the reporting.

Ituri province in eastern Congo has been identified as the outbreak’s epicenter. The wider affected area is near South Sudan, Uganda and Rwanda, and responders face rebel conflict and limited access to health care. Those conditions can make it harder to staff treatment facilities, monitor suspected cases and contain transmission.

A response under pressure

The central development is not a new case total or a declared global emergency. It is the WHO’s assessment that the outbreak is advancing more quickly than the measures intended to control it. The available report does not provide a current confirmed number of cases or deaths for the Congo outbreak.

At the same time, some health workers have stopped working over a lack of pay. The report does not establish that the strike has caused specific deaths or directly increased transmission. It does show that the response is facing a practical challenge: health services need personnel for treatment, surveillance and containment, while some workers say they have not been paid.

Access problems linked to rebel conflict add another obstacle. In eastern Congo, the combination of insecurity, limited health-care access and a rapidly growing outbreak creates risks for the basic functions of an Ebola response. Teams must be able to reach affected communities, identify possible infections and maintain care and monitoring.

Funding announced as the outbreak grows

The U.S. Department of State has announced an additional $242 million for Ebola response, preparedness and related humanitarian assistance. The announcement is broader than Ebola treatment alone, and the available information does not specify how much of that amount is dedicated solely to the outbreak.

The funding decision signals that the response is being treated as both an immediate health emergency and a preparedness challenge. But the announcement does not by itself resolve the operational problems described by the WHO: a response that is struggling to keep pace, unpaid front-line workers and difficult access in a conflict-affected setting.

The WHO described the Congo outbreak as the fastest-growing Ebola outbreak and the second-largest on record. That distinction should not be confused with the historical totals from West Africa’s 2014–2016 outbreak, which recorded more than 28,000 cases and over 11,000 deaths. Those figures are historical regional totals, not current counts for Congo.

What is known next

The immediate task is to strengthen the response in and around Ituri while maintaining access to health care and essential outbreak work. That includes treatment, surveillance and containment, all of which depend on functioning health services and personnel able to work.

No further case or death total, resolution date for the strike or separate deadline for the U.S. funding was provided in the approved report. The next significant measure of progress will be whether response operations can catch up with the outbreak’s spread in eastern Congo, particularly while conflict and unpaid wages continue to disrupt access and staffing.

The United Nations says an Ebola treatment center in Butembo, North Kivu, was raided and set on fire on July 6 as the outbreak in the Democratic Republic of Congo expanded into neighboring Ituri Province.

The attack has added a security threat to a public-health emergency that was declared on May 15. Health authorities reported 2,073 confirmed Ebola cases across five provinces as of July 14, according to a UN briefing. The UN also said security incidents had affected Ebola responders in Ituri, South Kivu and North Kivu.

The reported violence is obstructing the work of teams trying to identify cases, support treatment and contain transmission. The perpetrators of the Butembo attack were not identified in the UN account.

Cases reported in Ituri

Health authorities reported confirmed Ebola cases in the Boga Health Zone of Ituri Province, according to the UN’s July 8 briefing. The report did not establish a direct connection between those cases and the attack site in Butembo.

Butembo is in North Kivu, while Boga is in neighboring Ituri. Together with South Kivu, the provinces named in the UN security update show that response workers are facing risks in several parts of eastern Congo. The available updates do not provide a current death toll.

The UN’s July 21 Geneva briefing provided an update on the Bundibugyo-virus Ebola outbreak in the Democratic Republic of Congo and described it as an ongoing regional health emergency. The source packet does not provide additional detail about the virus beyond that briefing description.

Humanitarian funding needs increase

The outbreak is unfolding within a broader humanitarian crisis. The revised humanitarian response plan increased the funding requirement from $1.4 billion to $2.3 billion.

The plan includes $313 million for the Ebola response and aims to assist 10.8 million people by the end of the year. The higher figure describes the revised requirement; it does not mean that the full amount has been funded.

That distinction matters for communities and response teams. Health workers need access to affected areas, treatment facilities need protection, and humanitarian agencies are seeking resources for a response that extends beyond Ebola alone. The UN updates identify the funding target and intended reach but do not specify how much has been raised.

What happens next

The immediate response remains focused on containing the outbreak while maintaining operations in areas where security incidents have affected responders. The revised humanitarian plan sets an assistance target through year-end, while the World Health Organization and other response actors continue providing updates.

The latest information establishes three simultaneous developments: the outbreak has produced confirmed cases in five provinces, response personnel and facilities have come under attack, and the wider humanitarian funding requirement has grown substantially. It does not establish who carried out the Butembo attack, how many people have died, or whether all suspected cases are confirmed.

For communities in eastern Congo, the practical stakes are direct: insecurity can limit access to treatment and other health services at the same time that the number of confirmed cases and the scale of the humanitarian plan are rising.

The new allocation brings total U.S. aid for the outbreak above $500 million, according to reporting by Le Monde. The announcement followed Congo’s official declaration of an Ebola outbreak on May 15, after the virus had reportedly been spreading silently since late February.

A response under financial pressure

The funding decision comes as agencies working on food security and humanitarian relief have received only a fraction of the money requested for Congo’s broader response. Data from the United Nations Office for the Coordination of Humanitarian Affairs, cited by Le Monde, showed that food-security operations had received 25.2% of the funding requested in the humanitarian response plan.

That gap matters because the Ebola response is unfolding alongside broader humanitarian and food-security pressures. Health agencies must work in an environment where other life-saving operations are also seeking support, potentially making it more difficult to protect vulnerable communities while responding to the outbreak.

The available reporting does not establish that the funding shortfall caused the virus’s initial spread. It does show that the outbreak and the humanitarian funding crisis are occurring at the same time, increasing the demands on agencies operating in Congo.

Part of a wider regional funding strain

Reports from international institutions point to a wider funding challenge across parts of Africa, although those reports do not describe the Congo outbreak itself. A July 1 World Health Organization situation report said food insecurity and health emergencies were placing major pressure on humanitarian operations in Africa. It estimated that approximately $25.4 million was needed for priority life-saving health and nutrition interventions from July through December 2026 in the area covered by that report.

The United Nations Office for West Africa and the Sahel separately warned on July 23 that humanitarian needs and funding pressures were worsening across Sub-Saharan Africa. Its report projected that 15.4 million people in the Sahel would face acute food insecurity during June through August 2026. The Sahel projection is a regional context, not a measure of the Ebola outbreak in Congo.

Together, the reports describe a difficult operating environment for international relief organizations: a new infectious-disease response is competing for attention and resources while food insecurity and other health emergencies remain underfunded in several African regions.

What is known—and what remains unclear

The approved reporting does not provide a confirmed number of Ebola cases or deaths. It also does not establish how widely the outbreak has spread across Congo, and the available material cannot yet assess the effectiveness of the newly announced U.S. funding.

The $242 million is an announced allocation, not a confirmed amount already disbursed or spent. The funding announcement was reported by a secondary international outlet; a U.S. government or World Health Organization release would be needed for additional primary-source confirmation.

The next phase will require continued reporting from health and humanitarian agencies on the outbreak’s scope, the response’s effectiveness and the flow of funds. For now, the central development is the expansion of U.S. support at a moment when Congo’s Ebola response is taking place alongside a much broader humanitarian funding crisis.
