CDC: Airline passenger didn't have monkeypox

Updated 11:22 PM ET

(CBS News/AP) CHICAGO - Authorities say passengers aboard a Delta Air Lines flight from Detroit were kept from disembarking in Chicago for about three hours after one person was suspected of carrying a disease.

The Centers for Disease Control and Prevention says the passenger was evaluated shortly after the plane landed Thursday afternoon at Midway International Airport. The CDC says emergency medical personnel determined the woman's rash was not related to monkeypox, which had been suspected.

In its statement, the CDC says the woman was cleared but advised to seek medical care.

The incident occurred on Delta flight 3163, which landed at about 3:45 p.m. Passengers were kept aboard the plane for about three hours before being allowed off.

Earlier, citing multiple sources, WBBM Newsradio reports that the Centers for Disease Control was called to the scene in relation to a passenger who may have transferred from Africa with a visible rash. However, a subsequent report indicates that the emergency may have been a false alarm over "bug bites."

The aircraft was identified as flight 3163 from Detroit and landed at around 3:45 p.m. in Chicago. Fire department crews surrounded the aircraft, which has not been allowed to go to a gate.

Initially, no crews boarded the flight and no passengers or crew were allowed off, CBS Chicago reports.
