One of the reasons Ebola stays alive in Africa is that Ebola lives in Monkeys and many eat the Monkeys. The bodies have never been the big problem there. People keep infecting each other and the Ebola virus does stay alive for about 48 hours on anything. I thing that if there is many dead bodies everywhere that the bodies will not be infectious after a week and that also applies to the houses and buildings. The Ebola virus will just die.
