U.S. health authorities said Friday they have confirmed the country's second infection with a newly identified coronavirus that has been spreading rapidly from the central Chinese city of Wuhan.

An infected individual in Illinois returned from Wuhan on Jan. 13 and consulted a health care provider after experiencing symptoms a few days later. The patient remains hospitalized in stable condition and has been placed in isolation, the Centers for Disease Control and Prevention said.

The CDC said Tuesday that a man residing near Seattle had been diagnosed with a new coronavirus after traveling to Wuhan, becoming the first confirmed case in the United States.

"It is likely there will be more cases reported in the U.S. in the coming days and weeks," the CDC said in a statement, while stressing that the immediate risk of the new coronavirus to the American public "is believed to be low at this time."

The new coronavirus spreading rapidly in China has infected around 900 people and killed 26 in the country, while many other countries in Asia have also reported cases of the virus.
