It is not clear if she is lives in New Mexico or was there at the time she came down with Ebola-like symptoms.

The woman returned from Sierra Leone “earlier this month,” according to the Albuquerque Journal.

Though the woman supposedly had no “known” exposure to the virus while in the country, she’s being tested “out of an abundance of caution,” the newspaper reports.

KOB 4 reports the woman is “not a probable case, but a person under investigation …”

The Journal continues:

“The Department of Health is working closely with UNM Hospital and the Centers for Disease Control and Prevention on this investigation,” Department of Health Cabinet Secretary Retta Ward, said in a news release. “UNM Hospital has isolated the patient, and is following the appropriate protocols to ensure other patients and health care workers are safe.”

Health officials downplayed the concern to the newspaper, saying Ebola is “not a substantial risk to the U.S.”
