The Centers for Disease Control (CDC) said the patient left Liberia in west Africa on 19 September, but did not develop symptoms until after arriving in the US. He was admitted to the Texas Health Presbyterian hospital in Dallas on Sunday.
Thomas Frieden, the director of the CDC, said the patient was being treated in isolation. All measures would be taken to ensure that the disease would not spread in the US, he said.
â€œI have no doubt that we will control this case of Ebola so that it does not spread widely in this country,â€ he told a news conference. The disease has spread rapidly in west Africa, killing more than 3,000 people.
A spokeswoman for Dallas County health and human services department told the Guardian that it will be â€œconducting a public health follow-upâ€ on the patient which will include investigating his travel history and recent activity.
Health officials in Texas attempted to reassured residents. â€œDallas county residents should not have any fears at this point, there is not an Ebola outbreak in Dallas county,â€ Zachary S Thompson, the Dallas county director of health and human services, told the Dallas Morning News earlier on Tuesday, before the case was confirmed. â€œThere are great mechanisms put in place in terms of our public health infrastructure to look at these particular situations and look at the proper response.â€
