Since the discovery of Marburg virus 50 years ago, filoviruses have reemerged in the human population more than 40 times. Already the first episode was as dramatic as most of the subsequent ones, but none of them was as devastating as the West-African Ebola virus outbreak in 2013-2015. Although progress toward a better understanding of the viruses is impressive, there is clearly a need to improve and strengthen the measures to detect and control these deadly infections.
