“West Africa is in the midst of the worst Ebola outbreak in history.  The Centers for Disease Control and Prevention estimates that some 9,000 people have contracted the disease so far. Heath officials put the death toll at around 4,500, meaning that one in two people who get Ebola in this outbreak die.”
