ABSTRACT The Ebola virus is a pathogen that causes high morbidity and mortality in epidemic events during which health personnel are frequently infected. Such an epidemic occurred in West Africa, prompting WHO to issue a call in 2014 for health personnel to be dispatched to affected countries. Cuba responded and signed an assistance agreement under which 265 Cuban health professionals, members of the Henry Reeve Emergency Medical Contingent, volunteered their services in the Republic of Guinea, Sierra Leone and Liberia. This article presents Cuba’s strategy of medical aid and organization of the three medical teams formed; refers to the teams’ contribution to epidemic control in treatment centers where they worked alongside other personnel; and describes measures taken in Cuba to prevent the virus from entering the country through returning volunteers or other means. In the centers where Cuban medical teams worked with other health professionals in West Africa, case fatality decreased from 80%–90% to 24%, contributing to control of the epidemic; no Ebola outbreaks occurred in Cuba. During the epidemic, two Cuban health professionals died of malaria and one physician fell ill with Ebola. This paper includes an overview of the treatment and evolution of the latter case, a doctor who contracted the disease in Sierra Leone and was treated in Geneva and Havana.
