The World Health Organisation (WHO) and the Africa Centres for Disease Control and Prevention (Africa CDC) on Thursday, 27 August officially declared the end of the Ebola outbreak in Uganda, following 42 consecutive days without a new confirmed case since the country's last patient was discharged. The declaration marks a significant public health milestone for Kampala, though health authorities warn that the threat has not disappeared from the broader region.

Why 42 Days Is the Benchmark

The 42-day period is not arbitrary — it equals twice the upper limit of Ebola's incubation period, providing sufficient confidence that no undetected chains of transmission linked to the last imported case remain active. The WHO Regional Office for Africa described the completion of this window as a critical step in certifying the outbreak's end.

How Uganda Contained the Outbreak

Uganda reported 20 confirmed Ebola cases during the outbreak, including two deaths, following the initial outbreak declaration on 15 May. Of these, 15 cases were imported from the neighbouring Democratic Republic of the Congo (DRC), while five were locally acquired among contacts and health workers linked to the imported cases.

According to WHO, Uganda — with support from national and international partners — rapidly interrupted local transmission through strong government leadership and early, comprehensive measures. These included case detection and confirmation, contact tracing, isolation, and clinical care, as well as heightened surveillance at health facilities and points of entry.

What Global Health Leaders Said

WHO Director-General Tedros Adhanom Ghebreyesus credited Uganda's swift response, saying: 'Uganda has demonstrated that with decisive action, Ebola outbreaks can be brought under control quickly.' He added that 'with a focus on preparedness, increased surveillance to find potential cases in health facilities and communities, and careful management of points of entry, countries can keep people and goods moving while ensuring people stay safe, or receive care if they are sick.'

Africa CDC Director-General Jean Kaseya described the outcome as a continental lesson: 'Uganda has shown that Ebola can be stopped when leadership acts decisively, communities are trusted and public health systems reach people quickly.' Kaseya also issued a caution: 'This is a victory for Uganda and an important lesson for our continent. We must now protect this achievement while accelerating the response in the Democratic Republic of the Congo. We will only be secure when transmission is stopped everywhere.'

The DRC Threat Remains

Both WHO and Africa CDC stressed that while Uganda's outbreak is over, the DRC continues to battle active Ebola transmission. Close social and economic ties, frequent population movement, and cross-border trade mean neighbouring countries remain at risk of further imported cases.

Both institutions pledged continued support under a joint continental preparedness and response plan, with ending transmission in the DRC described as a central regional priority. Mohamed Janabi, WHO regional director for Africa, confirmed: 'WHO will continue working with the government and partners to help preserve these gains and keep communities safe.'

What Comes Next

Health authorities have indicated that surveillance will remain elevated at Uganda's borders, particularly along corridors with the DRC. The outbreak's containment — achieved despite the challenge of imported cases — is being studied as a model for rapid response in resource-constrained settings. Whether Uganda's gains hold will depend in large part on how quickly transmission in the DRC can be brought under control.
