title: The evolution of Ebola virus disease outbreaks.
abstract: The paper presents general information regarding descriptive epidemiology of Ebola virus disease (EVD) outbreaks. Some observations have shown the decrease in case fatality ratio after several generations of patient-to-patient passage. An increase in the frequency of EVD outbreaks across decades was also noticed. The knowledge about the past outbreaks may provide crucial information about the evolution of EVD epidemic, which may be useful for future preventions.
