A passenger who recently traveled to China and was showing flu-like symptoms was escorted off a plane at Baltimore/Washington International Thurgood Marshall Airport Saturday afternoon "out of an abundance of caution," airline and health officials say.

Medical officers escorted the passenger, who had been to Beijing, off of a Southwest flight from Las Vegas.

The Maryland Department of Health said in a statement the sick passenger did not meet the CDC's critical for coronavirus testing, but "was referred to a medical facility for evaluation to determine whether additional follow-up is necessary."

The person was released after a medical evaluation, the health department said.

A video provided to NBC from a passenger on the flight shows other passengers wearing masks over their mouths.

"Because of this heightened time, we are just using an abundance of caution," a health official can be heard telling the passengers in the video.

In an earlier statement to NBC, Southwest Airlines said the crew followed recommendations from the Centers for Disease Control "in light of the recent concerns of the coronavirus" and passengers would "receive the assistance or support they may need."

The sick passenger was previously screened and cleared in Mexico and Las Vegas, according to the health department.

The newly discovered virus from China has killed 56 people, sickened nearly 2,000 and prompted lockdowns of Chinese cities, putting the world on edge.

There are two confirmed cases of the coronavirus in the U.S., one of them a Chicago woman in her 60s who traveled to Wuhan in December and returned Jan. 13. She remains hospitalized in stable condition.

As of Friday, there were more than 60 unconfirmed cases of coronavirus in 22 U.S. states.
