On Friday, officials said the number of people placed under isolation in Dallas after possible exposure to Duncan had grown to at least 10, including four members of a family moved to an undisclosed house for close monitoring.  Initially, 100 people had been feared to have had direct or indirect contact. All those in isolation were cooperating with public health authorities by staying in quarantine voluntarily, according to Dallas city and county officials.  "There's no one under orders. There's no one that we perceive that needs to be under orders,'' Judge Clay Jenkins, Dallas County's top elected official, told a news conference late on Friday.  Separately, five public school children who had possibly been exposed to the Ebola patient had been kept home from class in recent days while being monitored as a precaution, though none had shown any symptoms, said Mike Miles, superintendent of the Dallas Independent School District.  Authorities have said the individuals placed in isolation included the four members of a single family whose apartment Duncan was staying in when he fell ill after traveling to Dallas from Liberia on Sept. 19. The six others are healthcare workers, including those who transported Duncan by ambulance on his second trip to the hospital on Sept. 28.  Duncan became ill on the night of Sept. 25 and visited the emergency room at Presbyterian Hospital, but was sent home with antibiotics and not screened for Ebola, despite telling a nurse there that he had just been to Liberia.  The hospital issued a statement on Friday saying that Duncan's travel history was "documented and available to the full care team,'' including doctors, through electronic records,contrary to the hospital's earlier assertions that staff were not made aware of his recent presence in West Africa.  Just days before flying to Texas via Brussels and Washington, Duncan had helped a pregnant woman who later died of Ebola in Liberia, a fact that he concealed from airport authorities in Liberia before boarding the plane.  Dallas County District Attorney Craig Watkins told a Dallas NBC News affiliate his office was considering whether to pursue a possible criminal case against Duncan, though he did notspecify on what basis Duncan might be charged.  The woman with whom he was staying, publicly referred to by city officials by her first name only but identified in the media as Louise Troh, was later ordered to stay inside her apartment with her 13-year-old son and two adult nephews who lived there with her.  On Friday, the family agreed to move voluntarily to an isolated four-bedroom house in a gated community in an undisclosed location somewhere within city limits, Jenkins said.  Arrangements for making the home available were made through a "faith friend,'' Jenkins said, describing the house as spacious and well equipped with amenities. He said the family members were free to venture outdoors on the property.  In the meantime, a cleanup crew contracted by local public health authorities finished the task of sanitizing the family's own apartment and removing perspiration-soaked bed linen, towels and other items used by Duncan.  Jenkins said the materials were placed in plastic bags, doused with bleach and then sealed in plastic barrels that were loaded onto trucks for shipment to an undisclosed location.  The hazardous materials trucks left the Ivy Apartments complex in Dallas on Saturday morning, bringing a sense of relief to neighbors worried about the virus.  "We are happy that they are gone,'' Thapa Lal Bahadur, an immigrant from Bhutan said, referring to the cleanup crews. "We had a fear about that virus.''
There have been inquiries about as many as 100 potential cases of Ebola in the US, but no new infections have been identified, a senior health official said on Saturday.
