U.S. officials on Thursday announced the country's 15th confirmed case of the new coronavirus — an evacuee from China who had been under quarantine in Texas.

The patient, who had been flown to Lackland Air Force Base in San Antonio last week, is now in isolation at a hospital and was reported in stable condition. The infection was confirmed through a Wednesday night lab test.

Two earlier U.S. cases were found among evacuees flown to Marine Corps Air Station Miramar in Southern California.

Hundreds of people, including U.S. State Department employees and their families, were brought to military bases in Texas, California and Nebraska aboard chartered flights from Wuhan, a city of 11 million that is at the center of the outbreak.
