A second case of new coronavirus has been identified in San Diego among evacuees from China, bringing the total number to eight in California and 15 in the United States.

The person was aboard a flight from the city of Wuhan that arrived at Marine Corps Air Station Miramar in Southern California last week, the CDC said.

The patient was in isolation at a San Diego hospital, UC San Diego Health confirmed.

Also in isolation is a woman who was mistakenly released because of a mislabeled sample that hadn't been tested for coronavirus. She was returned to the hospital on Monday after testing positive for the virus.

Originating in Wuhan, the new coronavirus has infected more than 60,000 people and killed more than 1,300 worldwide, according to the World Health Organization. The majority of cases are in China, but the virus has spread to at least 25 other countries. Two deaths have been recorded outside mainland China, one in Hong Kong and one in the Philippines.

In the U.S. 15 cases have been identified: eight in California, two in Illinois and one each in Arizona, Massachusetts, Texas, Washington and Wisconsin.

In California, Santa Clara, San Benito and now San Diego counties have seen two cases each, and there is one each in Los Angeles and Orange counties. (See maps in gallery above to see where cases have been found in the U.S. and around the world.)

The newly diagnosed patient in San Diego is expected to make a full recovery.

This new patient and the previously diagnosed one “arrived on different planes and were housed in separate facilities; there are no epidemiologic links between them," a CDC statement said.

A third person whose test results are pending also is hospitalized in isolation.

“We want to reassure our patients, their loved ones and the community at large that there is no exposure risk at any UC San Diego Health hospitals or clinics," the health system said in a statement.

Hundreds of people, including U.S. State Department employees and their families, have arrived at military bases in California, Texas and Nebraska aboard chartered flights from Wuhan, a city of 11 million that is the epicenter for the virus.

Recent chartered flights have sent hundreds of Wuhan evacuees back to the U.S. They are being held in quarantine at military bases in California, Texas and Nebraska.

A plane carrying 178 American coronavirus evacuees from Wuhan landed early Wednesday at Travis Air Force Base, 50 miles northeast of San Francisco. All evacuees will be quarantined for 14 days and staying in isolation at the Westwind Inn on Travis AFB. They won't have any contact with people living and working on the base. Five of the evacuees taken to Travis Air Force Base were hospitalized after showing symptoms of the virus and on Wednesday they were confirmed to not have the virus.

The only confirmed evacuee cases were at Miramar, where about 200 people are being held under quarantine until all are cleared.
