U.S. chartered plane from Wuhan lands in California

More than 200 U.S. citizens aboard a flight chartered by the U.S. State Department arrived in the United States from Wuhan Wednesday morning.

They will undergo three days of monitoring at a military base before they are released, but they will not be quarantined, said Chris Braden of the Centers for Disease Control and Prevention.

If any passengers ask to leave before the three days, CDC officials said they will make a determination.

Those who were evacuated reportedly were given health checks in China before they left.

Officials can still decide to quarantine passengers if they see a need, Braden said.

The plane landed at March Air Reserve Base in Riverside County, California, about 60 miles (96 kilometers) east of Los Angeles.

None of the passengers showed signs of the virus and they were screened before leaving Wuhan.

They were screened again during a refueling stop in Anchorage, Alaska.

During travel, the flight crew remained on the upper level of the plane, entirely isolated from the passengers for the entirety of the flight.

They did not get off the plane in China, putting them at low risk, said Anne Zink, Alaska's chief medical officer.
