Apparently they stayed at the timeshare, Grand Waikikian:
"
Hawaii's state health director, Bruce Anderson, said Friday that the couple was staying at Hilton Grand Vacations' Grand Waikikian on Oahu when the man began exhibiting symptoms on Feb. 3. He did not seek medical care at that time but was hospitalized upon his return to Japan and initially diagnosed with pneumonia before
testing positive for coronavirus.
"Hawaii's Department of Heath was later notified that the wife had been hospitalized, spokeswoman Janice Okubo
told Hawaiian Public Radio.
The Honolulu Star Advertiser and
The New York Times and reported that she was diagnosed with the virus on Saturday."
"Following the stay of a guest who was later diagnosed with COVID-19, the Grand Waikikian has implemented all recommendations of public health authorities," said Lauren George, the corporate communications director for Hilton Grand Vacations, an independent company which operates timeshares. "While the Grand Waikikian remains open as usual, we are also working with all current and future guests at the Grand Waikikian to ensure their comfort and safety."
Delta and Hawaiian AIrlines are working with the CDC to trace the path of a couple who were diagnosed with coronavirus after returning from Hawaii.
