Absolutely not. There are many infections in Africa that kill far more. Rabies is a big problem in Africa & Asia and kills someone every 10 minutes! This is much higher than Ebola! Just that Ebola is newsworthy at present whilst rabies is a neglected infection.
Because of Ebola, Africa will sink into the sea like Atlantis never to be seen again! No, that would be daft!
Africa will still be there after Ebola has gone, there will still be people living there, they will probably still be poor, they will probably still be undernourished, the instability may cause a few more wars, and obviously many people will have died but Africa will still be there and will still have many other problems!
