OMAHA, Neb. (AP) — For the second time this week, a person who has tested positive for COVID-19 after being evacuated from a cruise ship in Japan will be transferred to an Omaha hospital, officials said.

The person had been monitored at Travis Air Force Base in California, but was being flown to Omaha on Tuesday night, the University of Nebraska Medical Center said in a news release. The person is the spouse of one of 13 people already being monitored and treated at the Omaha hospital, hospital officials said.

The addition will bring to 15 the number of people being monitored at the Omaha hospital. Thirteen people are being monitored at the National Quarantine Unit, while two are receiving care at the Nebraska Biocontainment Unit. Two people continue to test negative for the virus and could leave quarantine March 2.
