A patient showing Ebola-like symptoms was put under evaluation at Yale-New Haven Hospital in Connecticut late on Wednesday. According to reports, the patient is a student researcher who had recently traveled to Liberia.

The hospital confirmed the news on Thursday morning in a statement: “We have not confirmed or ruled out any diagnosis at this point.”

Ebola scares have become common in the United States in recent weeks, but many have turned out to be false alarms. The three cases in Dallas have been the only confirmed Ebola diagnoses in the country. However, the New Haven case is drawing attention because two Yale health researchers had recently returned from Liberia and were not in isolation.

The campus’ student newspaper, the Yale Daily News, reported that the two researchers had originally agreed to sequester themselves for 21 days in case they started showing symptoms. But, after consulting with the Centers for Disease Control and Prevention, the university said the isolation was unnecessary.

The researchers had been in Liberia working on a computer model of the spread of Ebola, the Yale Daily News reported. Neither of the researchers came into contact with anyone infected with Ebola during their time there, according to the university.

The hospital did not release information on the patient’s identity or current condition. But local TV station WFSB reported that the patient was, indeed, a Yale researcher who had been in Liberia. That report was backed up by another TV station and the Hartford Courant.

New Haven officials: Yale researcher checked in with Ebola-like symptoms. The student has previously tested negative when left Liberia.

Other Ebola scares in the U.S. this week include one at Boston’s Logan Airport on Monday when a hazmat crew boarded an Emirates flight from Dubai after five passengers showed flu-like symptoms.

The U.S. is on high alert for Ebola cases after two nurses who treated Texas Ebola patient Thomas Eric Duncan contracted the virus. (Duncan died on Oct. 8.) Five airports around the country are now screening passengers traveling from West Africa for Ebola symptoms.
