How lethal is the Bundibugyo virus?
Dr. Geeta Sood, a hospital epidemiologist at Johns Hopkins Bayview Medical Middle, mentioned the Bundibugyo virus has a mortality charge of round 25% to 40%, decrease than different kinds of Ebola, which common round 50% to 60%.
The mortality charge for the Zaire kind, the commonest species of Ebola, is 60% to 90%, based on a 2015 research.
