Uganda has officially declared the end of the Ebola disease outbreak, which was confirmed on 30 January 2025 by Uganda’s Ministry of Health. The outbreak infected 14 people, two of whom were probable (not confirmed by laboratory tests) and caused four deaths (including two probable).
Disease outbreaks, such as Ebola, Marburg, and yellow fever, are not new in Uganda. The country has faced multiple outbreaks and, in doing so, has built a resilient health system capable of detecting and containing outbreaks rapidly. With active support from the World Health Organization (WHO) and other partners, this outbreak again demonstrated Uganda’s capacity to deal with such challenges.
The latest Ebola disease outbreak occurred in the bustling, highly mobile city of Kampala. In many places, such an announcement could have triggered widespread panic. But, within 72 hours of confirmation, the Ministry of Health, actively supported by the WHO and health partners, activated its response mechanisms. Rapid response teams were deployed on the ground, identifying contacts to the confirmed patient, collecting samples for testing, setting up treatment units, and educating the community about Ebola prevention.
Similarly, within 24 hours of notification, the WHO Deputy Director General and Executive Director for Emergencies, Dr Mike Ryan, was in Uganda to guide WHO’s strategic and operational support to the response.
“The outbreak occurring in an urban setting is of significant concern to us, given past experiences. In this outbreak, every minute is of the essence, and we must set up rapidly to avert a potential disaster,” said Dr Mike Ryan upon arrival in the country.
WHO mobilized 129 national and international staff to support the response. They brought a wealth of technical expertise, ensuring that WHO’s input was present at every critical stage.
The impact of these efforts was quickly evident. On 14 March 2025, the last confirmed patient was discharged, and 534 contacts had been successfully identified and followed up daily. This is no mean achievement given the area in which the outbreak occurred. It is a testament to Uganda’s strengthened capacity to detect and respond to disease outbreaks in line with the International Health Regulations (2005) (IHR), for which WHO is the principal custodian.
Uganda has now completed the 42-day mandatory countdown without a confirmed Ebola case. During this critical period, WHO worked closely with the Ministry of Health to conduct active case search and mortality surveillance to ensure that no potential chains of transmission went undetected.
It’s important to acknowledge the groundwork that made this rapid response possible. WHO’s presence on the ground through its regional hubs and prior technical leadership in helping Uganda develop a multisectoral preparedness and response plan were pivotal. These provided clear direction for all responding actors, enabling effective coordination, optimizing resource allocation, and preventing duplication.
Another key enabler was the swift deployment by WHO of 165 multidisciplinary Rapid Response Team members (RRTs) to hotspot districts. These members strengthened local capacity for alert management, case investigation, and contact tracing, even in remote areas. Backed by WHO’s technical training and tools, the RRTs worked hand in hand with district teams to ensure that no case went undetected. This strong collaboration helped halt the further spread of the disease.
Special attention was also given to border health. With the international imperative to prevent cross-border transmission, health workers were rapidly reoriented, thermal scanners were deployed, and screening protocols were enforced at 13 key entry points, especially at Entebbe International Airport.
The laboratory response was equally robust. Over 1500 samples were collected, transported, and tested, with national labs rising to the challenge. Thanks to WHO’s prior technical support, Uganda had the capacity to manage samples under strict biosafety and quality standards. Laboratory teams at the Uganda Virus Research Institute and Central Public Health Laboratories handled the workload professionally and efficiently, earning praise for their quick turnaround.
At the heart of the response was a courageous and well-prepared case management team. Equipped with WHO Ebola supplies designed to protect health workers and support clinical care, they treated patients with professionalism and care. Of the 12 confirmed cases, two patients succumbed, while the rest were successfully treated and reintegrated into their communities. Two probable cases were identified after their death, therefore not managed in the treatment center.
WHO-supported 78 Emergency Medical Teams (EMTs) further reinforced case management efforts. These highly trained and well-equipped teams ensured the safe transportation and treatment of patients across affected regions, delivering high-quality care at every step.
For the second time in an Ebola outbreak caused by the Sudan virus in Uganda, WHO deployed anthropologists, risk communication experts, and community engagement teams. These specialists worked directly with communities to address stigma, mistrust, and misinformation, while providing real-time public health information. Their efforts were instrumental in gaining trust and reinforcing safety practices.
Despite the absence of a licensed vaccine against the Sudan virus, candidate vaccines are in various phases of clinical trials, recommended by the independent WHO candidate vaccine prioritisation working group. Within four days of the government’s declaration of the outbreak, a randomized clinical trial for vaccine safety and efficacy using the ring vaccination approach was launched. In addition, the administration of Remdesivir treatment under the Monitored Emergency Use of Unregistered and Experimental Interventions (MEURI) protocol was initiated.
Ecological studies aimed at identifying the source of infection were initiated and are continuing. These are important because they help to anticipate risks of outbreaks as well as ensure health systems are well prepared and ready to detect outbreaks early and respond effectively.
Behind the scenes, coordination and partner engagement played crucial roles. WHO was responsible for aligning resources, reducing duplication, and maximizing impact. Through its coordination role, WHO mapped out key stakeholders and facilitated effective resource use at all levels of the response.
No successful outbreak response is complete without adequate financial backing. So far, WHO has mobilized and utilized US $6.2 million for this response. This support, along with in-kind contributions of essential medicines, supplies, and equipment, has been vital in maintaining the momentum of operations.
WHO acknowledges and deeply appreciates all partners who contributed through the WHO Contingency Fund for Emergencies (CFE), including: Germany, Norway, Ireland, Canada, France, New Zealand, Kuwait, Portugal, Philippines, Republic of Korea, Switzerland, Estonia, and the WHO Foundation. Thanks to the United Kingdom, the Republic of Ireland, the Netherlands, the European Commission – Health Emergency Preparedness and Response (HERA), International Development Research Centre (IDRC), European Commission – European Civil Protection and Humanitarian Aid Operations (DG ECHO) and the African Public Health Emergency Fund (APHEF) for supporting WHO’s interventions.
As the situation in Uganda stabilizes, this outbreak highlights three clear lessons: early preparedness saves lives, rapid response is critical, and WHO’s support remains vital, not only for Uganda, but for global health security.
