New guidelines from the World Health Organization for the personal protective equipment that health workers should wear when treating Ebola patients make clear that what you wear counts — but even more important is how you put it on and take it off. Health care workers often get infected even while wearing personal protective equipment, or PPE. Hundreds have become infected and have died at the front lines in West Africa. Dallas nurses Nina Pham and Amber Vinson were infected while taking care of Thomas Eric Duncan, the only person so far to die of Ebola in the U.S. Most experts think infection was due to a gear malfunction of some type — perhaps a small mistake made when taking off contaminated PPE.
