Ebola

So 2 Americans with Ebola are being brought to the U.S. so the disease can be further studied. Not to worry, even though the disease id contagious and incurable, precautions are being taken. Both patients are being placed into isolation bags where they will stay until they can be placed in an isolation ward. And I'm sure that all their colleagues back in Africa gave them a high five or a fist bump through the plastic bag as a sendoff.

What could go wrong?
