Dallas - A hazardous-materials crew planned to return Friday to a Texas apartment where the U.S. Ebola patient stayed to collect bed sheets and towels used by the infected man before he was hospitalized.
The family living in the apartment has been confined to their home under armed guard while public-health officials monitor them — part of an intense effort to contain the deadly disease before it can get a foothold in the United States.
Louise Troh, who shares the apartment with her 13-year-old son and two nephews, said she is tired of being quarantined and wants authorities to decontaminate her home.
"Who wants to be locked up?" she said Thursday. Private security guards and sheriff's deputies blocked the entrance to the 300-unit apartment complex.

Dallas officials were waiting for a permit to allow hazardous material taken from the home to be transported along state highways for disposal, city spokeswoman Sana Syed said Friday.
A cleanup crew hired by the county and state arrived Thursday evening to assess the job but did not complete it. They expected to return Friday.
The first Ebola diagnosis in the nation has raised concerns about whether the disease that has killed 3,300 people in West Africa could spread in the U.S. Federal health officials say they are confident they can keep it in check.
The family must be relocated before the cleanup can begin.
"The challenges are real," CDC Director Tom Frieden said Friday on ABC's "Good Morning America" when asked about Troh's situation. But, he said, "I am confident that we will get it sorted out today."
The confinement order, which also bans visitors, was imposed after the family failed to comply with a request to stay home, according to Dallas County Judge Clay Jenkins.
Meanwhile, Texas health officials expanded their efforts to contain the virus, reaching out to as many as 100 people who may have had direct contact with Thomas Eric Duncan or someone close to him.
None has shown symptoms, but have been told to notify medical workers if they begin to feel ill, said Erikka Neroes, a spokeswoman for the Dallas County Health and Human Services agency.
The at-risk group includes 12 to 18 people who had direct contact with the infected man, including an ambulance crew and a handful of schoolchildren. The others came into contact with that core group, she said.
"This is a big spider web" of people, Neroes said.
The virus that causes Ebola is not airborne and can only be spread through direct contact with the bodily fluids — blood, sweat, vomit, feces, urine, saliva or semen — of an infected person who is showing symptoms. Those fluids must also have an entry point.
For example, people might get infected by handling soiled clothing or bed sheets and then touching their mouth, or if they are not wearing gloves while doing those tasks and have a cut on their hand.
Duncan's neighbors in the Liberian capital believe he become infected when he helped a sick pregnant neighbor a few weeks ago. It was not clear if he had learned of the woman's diagnosis before traveling.
Nonetheless, Liberian authorities announced plans to prosecute Duncan when he returns, accusing him of lying about not having any contact with an infected person.
Duncan filled out a form Sept. 19 about his health and activities before leaving for Dallas. Among other questions, the form asked whether Duncan had cared for an Ebola patient or touched the body of anyone who had died in an area affected by Ebola. He answered no to all the questions.
Frieden dismissed suggestions that people traveling from West Africa should not be allowed into the U.S.
"The fact is that if we tried to seal the border, it would not work because people are allowed to travel," he told ABC. "It would backfire because it would make it harder to stop the outbreak."
Duncan arrived in Dallas on Sept. 20 and fell ill a few days later. An emergency room sent Duncan home last week, even though he told a nurse he had been in West Africa.
In a statement issued late Thursday, Texas Health Presbyterian Hospital said it followed communicable disease protocols by asking Duncan if he had come into contact with anyone who was ill. He replied that he had not.
A flaw in the electronic health records systems led to separate physician and nursing workflows, meaning the travel history documented by nurses was not passed onto physicians, hospital spokesman Wendell Watson said. He said the system has been corrected.
Duncan's symptoms included a 100.1 F temperature, abdominal pain, a headache and decreased urination, the hospital said. He said he had no nausea, vomiting or diarrhea. Based on that, the hospital decided to release him.
He returned two days later and has been kept in isolation since Sunday. Duncan was listed Thursday in serious but stable condition.
Also late Thursday, NBC News reported that an American freelance cameraman working for the network in Liberia has tested positive for the virus and will be flown back to the United States, along with the rest of the news crew.
