Ebola is a very virulent haemorrhagic fever, and is actually TOO virulent and deadly to be of great concern.... ALL people who catch it, get extremely ill very quickly (before the contagious stage) and end up too incapacitated by the fever to spread the virus (which is spread by contact with the blood and sweat of the victim). Because it is so deadly and incapacitating, it also tends to burn itself out very quickly.... In order for a virus to be easily spread, it actually has to be quite mild and less incapacitating (the direct opposite of Ebola).... There are other haemorrhagic fevers that are less deadly than Ebola, and more easily spread, if you really insist on getting hysterical about viruses.
