An important milestone for the family of Thomas Eric Duncan, and dozens of others now declared ebola free. New evidence of how hard it can be for the disease to prspread. And Tom llamas has more. Reporter: That group includes the paramedics who first brought Thomas Eric Duncan to this hospital. It's a milestone, as you mentioned. But there are still 75 hospital workers who wake up every morning hoping to show no symptoms. This morning, a big morning in Dallas. The first group of people quarantined and monitored for their close contact with Thomas Eric Duncan, now free and clear. 48 in total. Including Duncan's relatives and fiance, Louise troh. There's zero chance they carry the vice. Reporter: Duncan's fiance telling ABC news, we're so grateful that none of us has shown any signed of illness. Our heart gos out to the two brave women who have been infected by this terrible disease as they were trying to help him. Am bore Vinson, in stable condition, able to communicate with her parents. Her family said she contacted the CDC before flying to Cleveland to prepare for her wedding. The CDC cleared her for travel. When she learned about Nina Pham's up next, she is asked if arrangements could be made for her to fly back to Dallas as a precaution. But the family says the officials told amber her concerns were unfounded. Now a 30-member medical support team of 20 critical care nurses, 5 infectious disease doctors and five protocol trainers all being assembled. Now at the national institutes of health, Nina Pham, the other nurse, is fighting fatigue, still in fair condition. She's in very good spirits as of last night in my discussion with her. Reporter: Dallas officials releasing these photos of Nina's dog, Bentley. The center currently caring for him posted the pictures on Sunday with his caretaker clad in a biohazard suit. So far, Bentley showing no signs of the disease. Still, no answer on how Pham or Vinson were infected. They're asking all health care workers to have no skin showing, including the neck area.
