Everybody has heard of ebola, but what do we really know about this scary virus and the disease it can cause with the current ebola news i thought i could give my opinion as a biomedical scientist and a very practical and to the point analysis of what this disease is, how it spreads, how likely it is show up in developed countries and what you can do to prevent being infected if it ever does.
