Malaria is mosquito-borne; effectively a condition of geography. One moves to a non-malaria zone and is no longer susceptible; or one can invest in some mosquito netting and dramatically cut their risk. Caring for the infected or burying the dead does not increase the risk. Ebola is person-to-person and by all accounts highly infectious, particularly targeting caregivers. It's a recipe for a much more severe social breakdown. It's also clear the number of malaria cases is bounded, at a level that is in some sense "livable". It is not clear at what level Ebola will top out at; it may not be compatible with maintaining a functioning society in particularly hard-hit areas.
