HOUSTON, Texas — A man in Dallas is being isolated in a hospital after he showed signs of Ebola, the virus that has killed thousands of people in Africa.

Test results from the Centers for Disease Control and Prevention will be released on Tuesday, according to the Associated Press.

The identity of the individual has not been released. The Dallas-based Texas Health Presbyterian Hospital reportedly released a statement on Monday; the hospital claimed that due to the patient’s recent travel history and exhibited condition, it is likely that he has Ebola.

While Ebola has been widespread in Africa, only five people have been treated for it in the United States. A doctor, who is a U.S. citizen, was recently admitted by the National Institutes of Health after contracting Ebola while volunteering in Africa.

Ebola symptoms include high fever, headache, muscle aches, sore throat, weakness, and stomach pain, according to WebMD.

It is unclear what special steps, if any, Texas Health Presbyterian Hospital is currently taking to keep its employees and staff safe and away from the infected individual.
