That means the Ebola EVD variant is currently spreading across the African roads to the population of African long distance truckers and their prostitutes — “blood born” also means sexually transmitted — to everywhere in Africa.
The poverty of Africa means that local prostitutes do a great deal more anal than vaginal sex due to a lack of contraceptives and in particular condoms.
In a matter of weeks we will be seeing prostitute vector Ebola showing up with village headmen and African government officials across equitorial Black Africa.
The timing of this Congo outbreak fits that sexual mode of transmission.
We have already lost rural equatorial West Africa in Liberia and the Liberian cities are dying.
It is now a question of limiting the damage.
This is the MSDS sheet on Ebola.
It uses 23 days, not five days, as the survival time outside the host.

COMMUNICABILITY: Communicable as long as blood, secretions, organs, or semen contain the virus. Ebola virus has been isolated from semen 61 days after the onset of illness, and transmission through semen has occurred 7 weeks after clinical recovery (1, 2).
and
SURVIVAL OUTSIDE HOST: The virus can survive in liquid or dried material for a number of days (23). Infectivity is found to be stable at room temperature or at 4°C for several days, and indefinitely stable at -70°C (6, 20). Infectivity can be preserved by lyophilisation.
