Hawaii currently has no known coronavirus cases, and officials there are now scrambling to locate people that came into contact with the man during his time in Honolulu and Maui.
The man began showing symptoms of illness on February 3 - the couple's second week of vacation - while staying at a time-share on the island of Oahu. While on Oahu, he had cold-like symptoms, but no fever, Anderson said. The incubation period is believed to run between 2 and 14 days.
Hawaii officials were notified through the U.S Centres for Disease Control and Prevention (CDC) yesterday, and state authorities in turn alerted local health providers to be on the lookout for coronavirus-like illnesses.
"We do believe that this is a serious concern, and I want to assure you that this scenario is exactly what we've been preparing for and are prepared for", the governor said.
State officials are also working to identify who else might have had close contact with the man and determine whether they are showing any signs of illness.
While on Oahu, the tourist stayed at the Hilton Grand Hilton.
The State is still seeking more details on his exact itinerary including which places he visited and flights he was on. Eight cases are in California.

All but two of the cases were in people who had traveled to Wuhan, China, the epicenter of the worldwide outbreak. Japan is among the nations hardest, with 251 confirmed cases, a lot of them on a cruise liner quarantined in a port.
