I honestly don't buy into the whole vitamin C thing here. This isn't scurvy or the common cold. It might help? Intuitively vitamin K would seem more of a factor to me...

"Another thing we are looking at is what goes wrong with the immune response during viral infection. Our bodies are so good at responding to so many diseases, and in most cases we get sick for a couple of days and then we get better. Our response to Ebola is totally out of whack. The immune system appears to deliver a much more aggressive response than is necessary, one that causes a lot of damage to the body. That overreaction is a significant part of what makes infection with this virus so deadly.
What kind of damage is done by the overreaction?

The response is so strong that it triggers other pathologies. This can include diffuse intravascular coagulopathy, which is why the virus is often called a hemorrhagic fever virus. Normally, coagulation is constantly serving your body, so if you get cut you get a nice blood clot that seals you up. It’s a great way to keep your blood from leaking out. In the case of Ebola, you get clotting in inappropriate places, such as organs like the liver. The problem is, you have a finite number of clotting factors in your body, and they get depleted from the inappropriate clotting. When that happens, you have a hole in your body that needs clotting but won’t stop bleeding. All the small things that happen on a daily basis that are normally taken care of by coagulation are not working."

"In order to continue the chain reaction of the coagulation cascade, these four factors need to be activated in a chemical reaction that involves vitamin K."
