I think the key is quarantine. Ebola can thrive in the rainforest / low hygiene regions of the planet. Outside of that environment it has a tough time. I doubt it could live long in desert conditions. It is also a cultural thing as all the third worlders have their own cultural practices as well as traditional caring for the ebola victims. Here? Our touchy feely is limited. Here? Preparation of the deceased is totally different. Beyond that, the Liberians should be able to combat and contain it by changing the dietary dependency on easy bush meat..... and limiting contact with the infected and loads of soap and water. I would also think that ebola has a leg up on any compromised immune system and any already sickly people. I once heard that 85 percent of Africans also have hepatitis a, b and/or c. Then there are the traditional malaria and crap born diseases readily available in the immediate surroundings to make the system work even harder.
I read the other day that this is not associated with eating bush meat, is that incorrect?
