Medscape interviewed the CDC about the current Ebola outbreak. In it, the CDC reiterates that healthcare workers are at particular risk for infection.

Protect yourself using standard precautions (sometimes called contact or droplet precautions). This includes gloves, gowns, face mask, and eye protection when handling specimens from a potential victim.
