This outbreak was notable for its impact on the central region of Uganda, particularly affecting the Mubende District.

Background

Ebola virus disease (EVD) is a severe, often fatal illness in humans, caused by the Ebola virus. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is around 50%, but it can vary from 25% to 90% in past outbreaks.

Outbreak Timeline

The outbreak was first declared on 20 September 2022, when a case of Sudan ebolavirus was confirmed in the Mubende District. The initial case was a 24-year-old man who presented with symptoms consistent with Ebola and later succumbed to the disease. Following this, several other cases were identified, leading to a rapid response from the Ugandan government and international health organizations.

Affected Areas

The outbreak primarily affected the central region of Uganda, with the Mubende District being the epicenter. Other districts, including Kassanda, Kyegegwa, and Kagadi, also reported cases. The spread of the virus was facilitated by the movement of people between districts, which necessitated the implementation of movement restrictions and other public health measures.

Response Efforts

The Ugandan Ministry of Health, in collaboration with the World Health Organization (WHO) and other partners, launched a comprehensive response to control the outbreak. This included the establishment of treatment centers, contact tracing, community engagement, and the deployment of healthcare workers to affected areas. Vaccination campaigns were also initiated, although the Sudan ebolavirus does not have a licensed vaccine, experimental vaccines were used under emergency protocols.

Challenges

The response to the outbreak faced several challenges, including logistical difficulties in reaching remote areas, community resistance to public health measures, and the lack of a licensed vaccine for the Sudan ebolavirus. Additionally, the outbreak occurred in the context of the ongoing COVID-19 pandemic, which strained healthcare resources and complicated response efforts.

Conclusion

The 2022–2023 Uganda Ebola outbreak highlighted the importance of rapid response and international cooperation in managing infectious disease outbreaks. It also underscored the need for continued research and development of vaccines and treatments for all species of the Ebola virus.
