Ebola has a weakness that current PPE doesn't really exploit.
Right now you're probably using the giant blue, all plastic suits that block out everything. They block out even air. Creating your own little protective air bubble from the outside environment. Well from what I've read Ebola isn't an airborne virus so why're you treating it like it is?
If you can only get ebola from coming into contact with an infected persons fluids then it sounds to me like you could wear your gas mask and then wear stain resistant clothing. You need clothing that has been treated to be hydrophobic. There are already several companies that make and sell these. My personal vote is for the "Silic" shirt though. What I'm trying to say in short is that you are wearing suits that cover a range of threats when what you need is a threat specific one.
