(CNN) -- It can be exhausting nursing a child through a nasty bout with the flu, so imagine how 22-year-old Fatu Kekula felt nursing her entire family through Ebola. Her father. Her mother. Her sister. Her cousin. Fatu took care of them all, single-handedly feeding them, cleaning them and giving them medications. And she did so with remarkable success. Three out of her four patients survived. That's a 25% death rate -- considerably better than the estimated Ebola death rate of 70%.
