(CNN) — An American who was evacuated on a US-chartered jet from a cruise ship docked in Japan told CNN that she wasn’t aware that other passengers on the plane had tested positive for novel coronavirus until they landed.

Sarah Arana was one of more than 300 US citizens evacuated from the Diamond Princess over the weekend and flown to the states following the outbreak of coronavirus on the ship, which is docked off the Japanese port city of Yokohama.

Fourteen of the evacuees had tested positive for coronavirus before they boarded the evacuation flights, the US departments of State and Health and Human Services said in a joint statement early Monday, as the two flights carrying the evacuees were en route to US military bases in California and Texas.

‘I didn’t hear a single word’

Arana told CNN’s Kate Bolduan on “Erin Burnett OutFront” Monday night that she didn’t know that passengers on her flight had tested positive until she landed.

“I didn’t hear a single word about that until I literally heard it on the news when we landed,” Arana said. “It was widely being reported everywhere else and we were never informed about that.”

But Arana felt she was in good hands while on the evacuation flight and when she landed on US soil.

“On the plane we were with specialists … very knowledgeable doctors and CDC professionals,” she said. “I have no doubt that they did everything with extreme caution.”

She felt much more at risk while on the ship without information and specialists, she told Bolduan.

“I’m not worried about being exposed on the plane,” Arana said. “Those are fellow Americans of ours, they deserve to come home.”

While the evacuees have returned to the US, they are not going home just yet.

Evacuees with the virus being moved to different locations

The 14 passengers who tested positive are now being treated in various locations around the United States.

Four of the seven who arrived at Travis Air Force base in California were taken to health care facilities near the base, said Dr. William Walters of the US Department of State’s Bureau of Medical Services.

The other three, along with their spouses, were transported to the University of Nebraska Medical Center. They were joined there by the other seven passengers who tested positive and had initially arrived at Lackland Air Force base in Texas, Walters said.

The Diamond Princess evacuees who haven’t been infected will still undergo a 14-day quarantine.

Quarantine ending for others

Meantime, Americans who arrived at the Marine Corps Air Station in Southern California earlier this month in the first evacuation flights from Wuhan, China — the epicenter of the outbreak — are nearing the end of their quarantine.

The US State Department flights from Wuhan landed at MCAS Miramar in San Diego County, on February 5 and February 7.

About 160 people are expected to be released Tuesday morning, Capt. Matthew Gregory, MCAS Miramar’s director of communication, confirmed to CNN Monday night. Another group is expected to be released on Thursday. Gregory did not have details on Thursday’s release.

There have been two confirmed cases of coronavirus among the group. The first and second patients arrived on different planes and were housed in separate facilities, CDC officials said.

As Americans are returning to the US on government-chartered evacuation flights, commercial airlines are keeping tabs on passengers leaving the country who may have been exposed to people infected with the virus.

Delta Airlines is reaching out to passengers

Delta Air Lines is “proactively reaching out” to passengers who recently traveled on a flight from Honolulu to Nagoya, Japan, after learning that two passengers on that flight are being treated for coronavirus, a statement from the airline said.

“We are communicating with the appropriate public health officials, including U.S. Centers for Disease Control and Prevention and local Japanese authorities. The health and safety of our customers and crews is our top priority, and in cooperation with Japanese health officials, we are proactively reaching out to customers who were onboard that flight as well as taking the necessary steps to ensure the safety of our customers and crew,” the statement read.

Several airlines, including Delta and American Airlines, have already suspended flights between the United States and China due to concerns over the virus.

Delta previously said it will suspend flights between the United States and China until at least April 30.
