DALLAS, Texas — The first Ebola patient diagnosed in the United States died Wednesday morning in a Dallas hospital according to a hospital spokesman.
Thomas Eric Duncan was pronounced dead at 7:51 am at Texas Health Presbyterian Hospital, Dallas, where he was admitted Sept. 28 and has been kept in isolation, according to spokesman Wendell Watson.
Duncan’s condition was changed on Saturday from serious to critical.
Duncan carried the deadly virus with him from his home in Liberia, though he showed no signs when he left for the United States. He arrived in Dallas Sept. 20 and fell sick a few days later.
Others in Dallas still are being monitored as health officials try to contain the virus that has ravaged West Africa, with more than 3,400 people reported dead. They are also trying to lower anxiety among residents frightened of contracting Ebola, though the disease can be spread only through direct contact with the bodily fluids of an already sick person.
Health officials have identified 10 people, including seven health workers, who had direct contact with Duncan while he was contagious. Another 38 people also may have come into contact with him.
The four people living in the northeast Dallas apartment where Duncan stayed have been isolated in a private residence.
Everyone who potentially had contact with Duncan will be monitored for 21 days, the normal incubation period for the disease.
Duncan passed an airport health screening in Liberia, where doctors took his temperature and found no other signs of Ebola symptoms. But a few days after he arrived, he began to have a fever, headache and abdominal pain.
He went to the emergency room of Texas Health Presbyterian in Dallas on Sept. 24, but was sent home. By Sept. 27, his condition had worsened. An ambulance that day took him back to the hospital is in isolation.
The hospital has changed its explanation several times about when Duncan arrived and what he said about his travel history. It has acknowledged that Duncan told them on his first visit that he came from West Africa.
The government plans to begin taking the temperatures of travelers from West Africa arriving at five U.S. airports as part of a stepped-up response to the Ebola epidemic.
A federal official said Wednesday the screening will begin Saturday at New York’s JFK Airport. Screenings will start next week at Newark, Dulles, Chicago and Atlanta. The official was not authorized to describe the change by name and spoke only on condition of anonymity.
Separately, Homeland Security Deputy Secretary Alejandro Mayorkas said Customs and Border Protection agents are handing out information sheets to travelers with details of what symptoms to look for and directions to call doctors if they become sick within 21 days—the incubation period for Ebola.
