New details are emerging today on the first case of Ebola reported in the United States. The patient, identified as Thomas Eric Duncan, is reported to be in serious but stable condition.

UPDATE, 3p ET: Dallas health officials held a news conference with the latest information on the Ebola case.

UPDATE, 2p ET: In his latest report on "The Real Story," John Roberts said Duncan lied on a questionnaire when he left Liberia. He answered "no" to a question on whether he'd been in contact with anyone who had the Ebola virus.

It turns out Duncan helped carry a woman who was too weak to walk because of the virus. Liberian officials intend to prosecute Duncan if he ever returns to the country, Roberts reported.

Up to 100 people are now believed to have been exposed.

John Roberts reported this morning that officials wanted to make sure Duncan's family "stayed put" until Oct. 19. He said county officials encouraged the family to stay home, but weren't sure the family would comply.

"So they put it down on paper. That has the force of law so if they were to go out and try to mingle in the public they could potentially be arrested," Roberts reported.

According to reports, 80 people may have been exposed to the virus, including five children who were in close contact with Duncan as he became sicker.

Parents in the Dallas area are nervous amid reports that those kids then went to school.

Gov. Rick Perry said the children are being monitored and maintained that the virus cannot be transmitted until after symptoms appear.

Details of the man's 28-hour trip from western Africa emerged Wednesday. He flew on two airlines, took three flights, and had lengthy airport layovers before reaching Texas on Sept. 20.

Still, federal officials say other passengers on the flights are at no risk of infection because the man had no symptoms at the time of his trip.

Duncan left Monrovia, Liberia, on Sept. 19 aboard a Brussels Airlines jet to the Belgian capital, according to a Belgian official. After layover of nearly seven hours, he boarded United Airlines Flight 951 to Dulles International Airport near Washington, D.C. After another layover of nearly three hours, he then flew Flight 822 from Dulles to Dallas-Fort Worth International Airport, the airline confirmed.

According to the Centers for Disease Control and Prevention, Duncan sought medical care Sept. 25 in Dallas after falling ill the day before.

The hospital is now being called into question because they let Duncan leave after he went to the ER and told them he had just come back from Liberia.

Roberts reported that the hospital had just gone over their Ebola procedures with staff. A hospital official, however, said the information about Duncan's travels was not communicated to the "whole team."
