Standard PPE generally involves gloves and hand hygiene. Then you have patient populations that involve different degrees of isolation. Contact isolation for Clostridium for example, which requires the addition of a gown. Droplet isolation for flu, which you have the joy of mask and face shield. Airborne for TB, in which you have a particle mask and a negative pressure room. If you work in the ED, unless there is a red flag or a patient history, you risk initial exposure to whatever brought them in. Regarding Ebola, they've provided us with zero information as of yet. Now that it's in a large metroplex, there's a good chance it will travel, and there will be a learning curve in which some of us will be infected. In time, we'll learn how to deal with this, but there will be some losses. Welcome to the world of healthcare.
