In the summer of 2014, the World Health Organization (WHO) declared the outbreak of Ebola in parts of West Africa to be “a health emergency of international dimensions”. Before that, local governments had announced a state of disaster. For the first time since its discovery in 1976, Ebola had reached densely populated areas connected to international travel. Fear of a pandemic was spreading – a scenario that so far had been unthinkable. Among experts, Ebola was not considered a threat to the world population because previous outbreaks had remained local. Until the infection figures declined in June 2016, the deadliest form of the virus had spread across West Africa.
