The 2026 Ebola outbreak in eastern Democratic Republic of the Congo (DRC), declared a Public Health Emergency by the World Health Organization, is unfolding within a larger humanitarian crisis. The region faces armed conflict, mass displacement and reductions in humanitarian assistance. With more than 7 million internally displaced people and degraded health infrastructure, the capacity to detect, prevent and treat infectious diseases is critically weakened. Recent funding cuts have disrupted core public-health functions, including surveillance and procurement of medicines, compounding the effects of insecurity.
Disruptions to routine health services affect multiple disease-control programs beyond Ebola. Insecurity damages facilities, interrupts supply chains and limits access to diagnosis, treatment and follow-up care. Malaria remains a leading cause of illness and death in the region, especially among children and displaced populations; conflict has reduced access to insecticide-treated nets, rapid diagnostic tests and effective antimalarial treatment. These gaps also complicate Ebola surveillance because malaria and Ebola can present with similar clinical features.
TB and HIV services face analogous challenges. Interruptions in diagnostics, medicines and community-based care increase the risk of treatment failure, mortality and the emergence of drug resistance, particularly among displaced groups. Conflict-related sexual violence increases vulnerability to HIV and other sexually transmitted infections, while reductions in humanitarian services limit availability of post-exposure prophylaxis, reproductive-health care and psychosocial support.
The authors describe the situation as a syndemic, where armed conflict and humanitarian retrenchment interact with multiple infectious disease threats. The collapse or weakening of one part of the health system undermines control efforts across diseases. Ebola, malaria, TB and HIV are not isolated problems in eastern DRC; they overlap in affected communities and health facilities, and failures in surveillance, supply chains or clinical services for one disease reverberate across others.
Experience in eastern DRC highlights the shortcomings of narrowly targeted emergency responses in contexts where several health threats coexist. Reactive, disease-specific interventions can temporarily address single outbreaks but do not substitute for sustained systems that maintain prevention, diagnosis and treatment for multiple conditions. The correspondence argues for shifting preparedness and response strategies away from isolated vertical programs toward approaches that strengthen the broader health system.
A priority for epidemic preparedness in conflict-affected areas is protecting health-care delivery. Attacks on facilities, staff and humanitarian personnel directly disrupt surveillance, vaccination, clinical care and outbreak response. Ensuring safe access for health workers and protecting medical infrastructure are framed as essential obligations under international humanitarian law and as prerequisites for functional epidemic response. Without operational health facilities, timely detection, isolation and treatment cannot be achieved even with external resources.
The correspondence calls for restoration of humanitarian financing through flexible and sustained mechanisms that support both emergency response and routine services. Short-term, disease-specific funding is inadequate in protracted crises where communities face concurrent threats. Donors should prioritize financing models that allow rapid adaptation to changing epidemiological needs while maintaining core programs for malaria, TB, HIV, immunization and maternal health, and should invest in national and local health structures rather than parallel systems that become unsustainable when external support declines.
Integrated surveillance and service delivery are recommended in place of fragmented vertical approaches. Since the same communities and facilities manage overlapping risks from Ebola, malaria, TB and HIV, combining resources—community health workers, laboratory platforms, surveillance systems and supply chains—would increase efficiency and resilience. Lessons from prior Ebola responses in eastern DRC emphasize the importance of community engagement, trust-building and locally adapted interventions to improve acceptance of public-health measures and maintain continuity of care.
Reliable access to essential medicines and diagnostics must be guaranteed. Stock-outs of antimalarials, TB drugs, antiretroviral therapy, rapid diagnostic tests and personal protective equipment can convert manageable conditions into public-health emergencies. The authors recommend establishing strategic buffer stocks, improving procurement transparency and strengthening last-mile distribution in conflict-affected areas to prevent treatment interruptions and reduce dependence on informal medicine markets.
Beyond immediate operational measures, eastern DRC needs epidemic preparedness founded on resilient primary-healthcare systems that can sustain essential services during conflict and displacement. Protecting routine programs is presented as a cornerstone of outbreak preparedness. The correspondence concludes that without sustained investment to strengthen health-system resilience, the vulnerabilities of this fragile health system will remain exposed, reversing years of progress in controlling Ebola, malaria, TB and HIV.
