The latest Ebola outbreak is the largest, most severe and most complex ever recorded for the disease. With a death rate of around 55% and more than 1000 victims thus far, it has been declared a public health emergencyof international concern by the World Health Organization (WHO). While specific treatments or vaccines currently do not exist, several interventions are in the earliest phases of testing. WHO released a statement on 12 August that “it is ethical to offer unproven interventions with as yet unknown efficacy and adverse effects, as potential treatment or prevention.”
