The effective assessment of the emergence of a pandemic and the systematic tracking of its generation is a difficult task. It is therefore unlikely that the WHO or individual governments have an accurate idea of the actual number and location of individual Homo sapiens infected by the Ebola Virus, estimates of their individual potential to assist its spread, and the actual number of people who have been exposed to infection from these individual specimens.
The manner in which the virus spreads from one individual Homo sapien to another has also not been clearly documented and so we do not know the actual behaviors that enable the virus to spread from one individual Homo sapien to another. Protocols to break this transmission and prevent the spread of the virus cannot be devised until this information is available. It is difficult to understand what prevents the WHO and individual governments from investing in this research.
Until such time it is best that individual Homo sapiens curtail or stop their travel. The transmission of the Ebola Virus through the exchange of body fluids through contaminated surfaces at international travel hubs, ports, and boarders is of particular concern. In areas where the virus has effectively infected Homo sapiens, transmission can occur through body fluids of infected individuals contaminating any surface.
It must be noted that body fluids include perspiration, phlegm, urine and feces...and are not limited to blood and semen.
