The World Organisation for Animal Health (WOAH) has issued a formal statement alerting member nations to active Ebola virus disease (EVD) transmission in the Democratic Republic of the Congo (DRC) and Uganda. The outbreak underscores the zoonotic origin of Ebola and the critical need for coordinated surveillance across animal and human health sectors. WOAH’s involvement signals recognition that controlling animal reservoirs is essential to preventing further human spillover events.
Key takeaways
- WOAH has documented active Ebola virus circulation in both the Democratic Republic of the Congo and Uganda
- Ebola remains a zoonotic disease requiring integrated animal and human health surveillance
- Cross-border transmission risk is elevated in East-Central Africa, demanding coordinated regional response
- Healthcare facilities in affected regions require enhanced infection control and biosafety measures
WOAH Confirms EVD Circulation in Two Nations
According to the WOAH statement, Ebola virus disease cases have been confirmed in both the DRC and Uganda, marking a significant public health incident in the region. The statement emphasizes the importance of animal health monitoring in areas where wildlife-human contact occurs, as previous Ebola outbreaks have traced their origins to contact with infected animals in these geographic zones. WOAH’s formal communication to member states indicates the organization views animal surveillance as integral to the broader outbreak response.
The involvement of WOAH—the international standards-setting body for animal health—reflects a One Health approach to infectious disease control. This framework integrates veterinary, human, and environmental health strategies to identify and contain zoonotic pathogens before they establish human-to-human transmission chains. The DRC and Uganda, both with significant populations of wildlife reservoirs, face particular vulnerability to spillover events.

One Health Response: Integrating Animal and Human Surveillance
The WOAH’s engagement in this outbreak response demonstrates that controlling Ebola requires coordinated action across veterinary and public health sectors. Previous Ebola outbreaks—including the 2014–2016 West African epidemic—have revealed gaps in cross-sector communication and animal disease monitoring. In the DRC, where multiple Ebola outbreaks have occurred in recent years, strengthening wildlife surveillance networks and training veterinary personnel in diagnostic protocols is essential.
Healthcare facilities in affected and adjacent regions must implement strict infection prevention and control (IPC) measures. The WHO’s infection control guidance for Ebola specifies protocols for managing suspected cases, including personal protective equipment (PPE) standards, safe burial practices, and laboratory biosafety protocols. Given Uganda’s proximity to the DRC outbreak zone, border health facilities are priority sites for IPC strengthening and staff training.
Regional Transmission Risk and Cross-Border Challenges
The simultaneous presence of EVD cases in the DRC and Uganda raises concerns about cross-border transmission dynamics. The porous borders in the East-Central Africa region, combined with population movement for trade and family connections, create conditions for rapid geographical spread. WOAH’s alert to member states signals the need for enhanced disease reporting and coordination between the ministries of health and agriculture in both countries.
Vaccination remains a critical tool for outbreak containment. The Ervebo (rVSV-ZEBOV) vaccine has demonstrated efficacy in ring vaccination campaigns, where contacts of confirmed cases are prioritized for immunization. Availability and rapid deployment of vaccine supplies in DRC and Uganda will be essential to limiting further transmission. Additionally, community engagement and public communication about Ebola transmission routes and prevention measures are vital, particularly in regions with previous outbreak experience where community trust has been affected by past epidemics.
What this means
Frequently asked questions
How is Ebola virus transmitted between humans?
According to WHO guidance, human-to-human transmission occurs through direct contact with blood or body fluids of infected individuals, or with surfaces and materials contaminated by these fluids. The virus enters through breaks in the skin or mucous membranes. Healthcare workers and family members caring for patients face elevated risk without proper IPC measures.
What is the case fatality rate for Ebola virus disease?
Ebola virus disease has a historically high case fatality rate, typically ranging from 50% to 90% depending on the virus species and quality of supportive care available. Survival improves significantly with early diagnosis, aggressive fluid replacement, electrolyte balance, oxygen support, and treatment of secondary infections in healthcare settings equipped for critical care.
Why does WOAH issue statements on human disease outbreaks?
WOAH issues alerts on zoonotic diseases like Ebola because animal surveillance is essential to outbreak prevention and control. Understanding where the virus circulates in wildlife and domestic animals helps identify spillover risks and informs vaccination and containment strategies. The One Health framework recognizes that human epidemic control begins with animal health monitoring.
The WOAH statement serves as a critical signal to the global health community that Ebola remains an active threat in East-Central Africa and that sustained, coordinated action across sectors is required. As regional laboratory capacity and vaccine availability improve, the DRC and Uganda have better tools to contain transmission than were available during previous outbreaks. However, success depends on rapid case identification, rigorous contact tracing, and community cooperation—all of which require ongoing investment and international support. Monitoring this situation closely and documenting lessons learned will strengthen future pandemic preparedness across the region and globally. For the latest updates, clinicians and public health officials should monitor WHO emergency alerts and Global Health news from GMJ.
