I'm sure that there's a protocol you could follow to prevent catching the flu from flu patients, too, but I doubt it would be practical to practice medicine at the same time. I think that as Western medical personnel are beginning to be infected, it becomes less easy to just say "the training/equipment/conditions were the problem". At some point, we need to look at how the containment protocol interacts with the treatment protocol, and see if it actually works.
Remember, correctly executed withdrawl is just as effective a form of birth control as a correctly applied condom, but a greater share of condom users use them correctly than those who attempt pulling out.
