DALLAS (AP) — There’ll be more stringent procedures for health care workers taking care of Ebola patients in the U.S.

The Centers for Disease Control and Prevention says health care workers will have to wear full-body suits and hoods, covering every part of their body, and they’ll be checked by at least one other person when entering and leaving contaminated areas.

The changes come after two nurses who took care of an Ebola patient in a Dallas hospital contracted the virus themselves.
