Evolution of Ebola Virus Disease from Exotic Infection to Global Health Priority, Liberia, Mid-2014
“Reviewing that first phase in the light of subsequent events, our townsfolk realized that they had never dreamed it possible that our little town should be chosen out for the scene of such grotesque happenings as the wholesale death of rats in broad daylight or the decease of concierges through exotic maladies.”
—Albert Camus, The Plague (1948)
The Ebola virus disease (EVD) epidemic in West Africa is recognized as the largest in history; more cases reported than in all previous EVD outbreaks combined (1). However, until the summer of 2014, the epidemic had not captured the world’s attention.
The EVD epidemic began in Guinea in late 2013. In neighboring Liberia, EVD was first diagnosed in a patient in mid-March 2014. A team of epidemiologists from the US Centers for Disease Control and Prevention (CDC) began working with the Liberian Ministry of Health and Social Welfare (MOHSW) in early April. By April 9, a total of 12 EVD cases (6 laboratory-confirmed) had been identified in Liberia, but no additional cases were reported in April or during most of May, and it appeared that the outbreak had been contained locally. However, on May 25, a patient who had traveled from Sierra Leone died of suspected EVD in Lofa County in northern Liberia. Within days, additional EVD cases were reported in Lofa County and in Monrovia, the capital city of Liberia. The MOHSW initiated investigations into what was considered a second epidemic wave of EVD.
