Separately, one U.S. citizen died in China.

Two charter flights carrying 340 passengers who had been on the Diamond Princess cruise ship arrived at military bases in California and Texas late Sunday and early Monday. All but one of the coronavirus-positive evacuees are at the University of Nebraska Medical Center in Omaha.

WHAT TYPE OF ECONOMY DOES CHINA HAVE?

The State Department announced later that 14 of the evacuees received confirmed they had the virus but were allowed to board the flight because they did not have symptoms. They were being isolated separately from other passengers on the flight, the U.S. State and Health and Human Services said in a joint statement.

The rest of the virus infection cases are scattered in Arizona, California, Illinois, Massachusetts, Texas, Wisconsin and Washington state. The patient list includes at least two pairs of spouses.

CORONAVIRUS INCUBATION PERIOD COULD BE AS LONG AS 24 DAYS

Two individuals brought to California after being evacuated from Wuhan, the city at the center of the outbreak in China, have tested positive for coronavirus.

One Wuhan evacuee tested negative at first and was allowed to return to quarantine at Marine Corps Air Station Miramar in California. The patient was returned to UC San Diego Health on Monday after further testing resulted in a positive, the hospital said.

The patient has not been confirmed as a U.S. citizen.

Nearly 200 evacuees who were on the first flight from Wuhan but did not test positive for the virus were released from quarantine last week.

Meanwhile, China's lockdown in response to the outbreak is having ramifications on businesses around the world.

Major U.S. airlines have suspended nearly all flights to mainland China and Hong Kong. American Airlines announced last week that it's extending its suspension of flights to and from mainland China and Hong Kong from Dallas-Fort Worth and Los Angeles airports. Flight cancellations will now last until late April instead of late March.

California — 9

Thirteen of the 14 Diamond Princess evacuees who tested positive were taken to Nebraska, but one remained behind at Travis Air Force Base in California, USA Today reported on Monday.

The state confirmed its first cases in January. Confirmed cases are two patients in Santa Clara County, two in San Diego, two in nearby San Benito County, one in Los Angeles County and one in Orange County.

CORONAVIRUS CASE CONFIRMED IN SAN DIEGO

"The two cases in San Benito County are spouses, one of whom traveled to China and one who did not," the California Department of Public Health said in a statement. "This marks the first instance of close household person-to-person transmission of novel coronavirus in California. There is no evidence of person-to-person transmission in the general public in California."

The health department is working with labs throughout California so that the facilities are able to rapidly test for the virus.

Illinois — 2

A husband and wife who became sick in January were the nation's "first instance of person-to-person spread," CDC said.

The Chicago woman, who is in her 60s, returned from central China Jan. 13. Last week she went to a hospital with symptoms and was diagnosed with the viral illness. Her husband did not travel to China and caught the virus from her.

Authorities released them from home isolation on Friday.

"[T]here has been no further spread of the virus from these two cases," Illinois Department of Public Health Director Dr. Ngozi Ezike said in a statement. "The risk to the general public remains low and we are continuing to use every tool at our disposal to keep our community safe."

Massachusetts — 1

A Boston man in his 20s who had recently returned from Wuhan is the state's only confirmed case of coronavirus.

The patient has been reported as a University of Massachusetts student.

Nebraska — 13

Thirteen Diamond Princess evacuees arrived at the National Quarantine Unit on the UNMC/Nebraska Medicine campus on Monday. The facility cared for three patients with Ebola in late 2014.

Texas — 1

U.S. officials on Thursday announced the country's 15th confirmed case of the new coronavirus — an evacuee from China who had been under quarantine in Texas.

The patient, who had been flown to Lackland Air Force Base in San Antonio last week, is now in isolation at a hospital and was reported in stable condition. The infection was confirmed through a Wednesday night lab test.

Washington — 1

The Washington man who returned from Wuhan with coronavirus was discharged from Providence Regional Medical Center in Everett, Washington, in early February, MyNorthwest reported.

"I am at home and continuing to get better," the man said in a statement. "I ask that the media please respect my privacy and my desire not to be in the public eye. I would like to thank the doctors, nurses, and entire team at Providence who cared for me. I appreciate all of the concern expressed by members of the public, and I look forward to returning to my normal life."
