The United States now has one confirmed case of Ebola, the Centers for Disease Control and Prevention said, marking the first domestic appearance of the deadly virus that has ravaged swaths of continental Africa.

The Ebola epidemic has overwhelmed public health workers in three African countries, one of which was the likely site of infection of the first American case. At least for now, the incident remains isolated. However, CDC officials say the virus incubated here in the U.S. for at least a few days, and others have been exposed.

The as-yet unidentified patient is located in Dallas's Texas Health Presbyterian Hospital. Texas Gov. Rick Perry says a handful of school-aged children who had contact with the man are being monitored.



In a press conference on Tuesday, CDC Director Tom Frieden said the patient in question was traveling through Liberia, where he may have contracted the disease. He entered the United States on the 20th of September, after which he sought care. Reports surfaced that the man is a Liberian national in the U.S. visiting relatives.

"There may be a small outbreak because he did walk around with symptoms," said Debra Spicehandler, an infectious disease expert at Northern Westchester Hospital in Mount Kisco, NY. "So we may see a few more cases related to him."

On Wednesday, Texas health professionals were monitoring a clutch of potential citizens that may have come into contact with the hospitalized victim. Zachary Thompson, director of Dallas County Health and Human Services, told a local station that there might well be "another case that is a close associate with this particular patient."

Frieden attempted to assuage concerns about Ebola's contagious effect, saying that the virus was only spread through direct contact, and was not airborne. He vowed that officials would contain a potential spread.

Frieden added that "there is no doubt in my mind that we will stop it here," Frieden said.
