Unless she is trained to work in a containment suite, there is little chance she would be involved with the care of an Ebola patient brought to that hospital.
The containment suites are built in such a way that no virus will ever escape. Workers entering the suite wear impermeable spacesuits. An accidental needle stick or other event that causes damage to the spacesuit could expose a worker... but short of penetration with sharp objects, the suits are impermeable.
I’d think that the case of the American who collapsed and died in Nigeria, passing his infection on to at least eight others who cared for and cleaned up after him, would be a worst case scenario. Once they get to the containment facility, things are more controlled and safer, even for the medical staff.
