How Ebola works


The MicrobeWiki has a really detailed explanation of the biological mechanisms behind an Ebola infection. It gets a little technical in places, but it's a good read if you've ever wondered how the virus creates hemorrhaging and why it's hard to treat.

One of the reasons that Ebola is so deadly is that it has multiple ways of interfering with or avoiding the human immune system. While the virus is busy destroying the human body, the immune system is either still in the process of discovering that there is a problem, or is in such disarray that it would be next to impossible to mobilize a unified effort to fight off the invader.
