The US diplomats and their families traveling on a charter flight from Wuhan, China may be forced to stay isolation between three days and two weeks, a San Bernardino County, California, official told CNN.

Curt Hagman, chairman of the San Bernardino County Board of Supervisors, said authorities are setting up beds, phone chargers and televisions in an isolated, dormant hangar at Ontario International Airport, as they wait to receive a group of US citizens who left Wuhan, China with a final destination to Ontario, California.

“They’re going to be isolated from the plane. They’re not going to the public areas of the airport. They’re not going to be exposed to the general public until CDC clears them to go on their way,” Hagman said.

Upon arrival in California, the travelers will be offloaded into the hangar on the opposite side of the airport from the public terminals. Hagman said Ontario’s airport was chosen because it’s one of two airports designated by the US government for repatriations on the West Coast.

Hagman said after the travelers are screened for coronavirus during a refueling stopover in Anchorage, Alaska, they’ll be screened again in Ontario. Hagman notes there are no indications any of the travelers have the virus.

His messages to the community: “Don’t panic this is what we’ve been trained for.”

Hagman said they have no idea how long the travelers will be staying, and they are getting ready to have them watch the Super Bowl in an airport hangar if needed.
