Officials have now identified 16 people, up from 12, who came into close contact with Ebola patient Amber Vinson. The person at highest risk is her stepfather, who is now under strict quarantine.
Vinson traveled from Dallas to Cleveland and back last week on Frontier airlines.
Frontier has finished notifying some 800 passengers who flew on either of her two flights, as well as those who traveled on those same planes, about Vinson's diagnosis.

CNN has obtained new images from inside the plane that nurse Nina Pham flew from Dallas to a new hospital, the National Institutes of Health in Maryland.
In the photo, health care workers on board are no longer wearing hazmat suits. It's a stark contrast to the pictures of them loading her onto and off of the plane, where they were in full gear.
During the 3-hour flight, Pham flew in the rear of the plane in a specialized containment tent. Health officials say doctors downgraded her condition early Friday because she was fatigued from the trip.

Another Dallas health care worker is under quarantine, this time on a cruise ship in the Caribbean. Officials says this passenger may have handled lab specimens from late Ebola patient Thomas Eric Duncan.
