How to prepare for the next inevitable Ebola outbreak: lessons from West Africa

The West African Ebola virus disease (EVD) outbreak in 2014 emerged in a region in Africa that had previously not reported any EVD outbreak. Subsequently, the outbreak rapidly spread and was protracted in the three Mano River basin countries (Guinea, Sierra Leone and Liberia), with spillover cases in Nigeria, Senegal and Mali and, for the first time, importation into Europe and the USA. It became the most extensive and protracted EVD outbreak in history, followed by the 2018 outbreak in the Democratic Republic of the Congo (DRC). For the first time, cases were reported in urban centers, underscoring the urban spread of the disease. Its devastation had a far-reaching impact on lives in the three largely affected countries for years to follow. A total of 28,616 cases and 11,310 deaths were reported from Guinea, Sierra Leone and Liberia, with an additional 36 cases reported from Italy, Mali, Nigeria, Senegal, Spain, the UK and the USA.
