If an outbreak lasts longer than individual patients are sick (earlier patients have either died or recovered), then you could start recruiting survivors to help care for victims later in the outbreak. This will work better for diseases with lower mortality (e.g. the 1918 Spanish Flu) than one with a higher mortality like Ebola (Wikipedia says a 56% mortality rate, but maybe that includes people who are still sick and haven't died yet). This assumes that surviving the disease confers serious immunity, which I believe is normally the case, but I don't really know. In the case of Ebola it also assumes a relatively fast recovery time if the disease doesn't kill you, but I don't know if that is true either.
