"A few patients do bleed to death, Rollin said, but "they don't explode, and they don't melt." In fact, he said, the conventional term then in use, "Ebola hemorrhagic fever," was itself a misnomer, because more than half the patients don't bleed at all. They die of other causes, such as respiratory distress and shutdown (but not dissolution) of internal organs. It's for just these reasons, as cited by Rollin, that the WHO has switched its own terminology from "Ebola hemorrhagic fever" to "Ebola virus disease."
