WASHINGTON (AP) — Revised guidance for health care workers treating Ebola patients will include using protective gear “with no skin showing,” a top federal health official said Sunday, and the Pentagon announced it was forming a team to assist medical staff in the U.S., if needed.

Dr. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, said those caring for an Ebola patient in Dallas were left vulnerable because some of their skin was exposed.
