(CNN)The chartered flights carrying US citizens from Wuhan, China, this week are likely to be the last.
Two flights out of Wuhan, the epicenter of the novel coronavirus outbreak, landed Wednesday morning in California, bringing the number of such flights arriving in the US since January 29 to three.
Another two flights from Wuhan are scheduled to come later this week -- one headed to Lackland Air Force Base in San Antonio, Texas; the other going to Eppley Airfield in Omaha, Nebraska, the US Centers for Disease Control and Prevention said.
Canada's Foreign Affairs Minister Francois-Philippe Champagne said Washington has offered a few dozen of its seats on an evacuation flight to Canadians.
The US State Department does not anticipate chartering any flights after this week, a State Department official said Tuesday.
There are now 12 confirmed cases of coronavirus in the United States.
Two flights landed Wednesday: 'We are very grateful for the ride home'
Two flights -- carrying a total of about 350 passengers, according to the US Defense Department -- landed Wednesday morning at Travis Air Force Base, located between San Francisco and Sacramento.
About 178 passengers from one plane are staying at Travis. The other plane refueled before taking its passengers to Marine Corps Air Station Miramar in San Diego later in the morning.
The passengers at both locations will be under a 14-day quarantine managed by the US Centers for Disease Control and Prevention, Defense Department spokesman Lt. Col Chris Mitchell said.
Video recorded by passenger Frank Hannum showed what it was like in one of the planes that landed Wednesday.
Passengers sat in the cabin, wearing masks, as some State Department staff and health workers walked around the plane or stood, donning protective gear -- some of them nearly head to toe.
In the background, a large sheet of plastic separated the area where these passengers were sitting from the rest of the plane.
Someone at the front of section, using a megaphone, made an announcement about what would happen when the plane landed at Travis Air Force Base, including details about the two week quarantine.
