2017 Democratic Republic of the Congo Ebola virus outbreak is attempting to obtain and review Rwanda's public health rationale and relevant scientific information for implementing these measures. The sub-type "Zaire ebolavirus" has been confirmed in the current outbreak, from the family Filoviridae. It is a single stranded RNA virus, with a 60-90 percent mortality rate (the highest among the strains). An unusually high mortality has been reported in the local pig population.
