State health officials confirmed Friday that a Japanese tourist came down with symptoms of coronavirus during a vacation in Hawaii.
The patient and his wife visited the island of Maui from January 28 to February 3, then traveled to Oahu, where they stayed until flying on February 7 back to their home in the Aichi Prefecture of central Japan, the officials said.
The State is still seeking more details on his exact itinerary including which places he visited and flights he was on.
Health Director Bruce Anderson says officials believe that someone who doesn't have symptoms probably can not transmit the virus.
Hawaiian officials are on high alert after a recent vacationer tested positive for the coronavirus after returning to Japan, reports said.
Hawaii Department of Health's state epidemiologist, Dr. Sarah Park, said the man likely contracted the coronavirus before or en route to Hawaii.
The man's apparent lack of fever while in Hawaii also bodes well because infected individuals are believed to be most contagious when feverish, she said. He did not seek medical care in Hawaii, Anderson said.
He is from Japan's Aichi Prefecture. The incubation period is believed to run between 2 and 14 days.
Japan has about 250 confirmed cases of the new disease that apparently started in Wuhan, a city in central China, in December. Japan is among the nations hardest hit, with 251 confirmed cases, a lot of them on a cruise liner quarantined in a port.
So far, only 15 US cases of the coronavirus have been confirmed, and no deaths. All but two of the cases were in people who had traveled to Wuhan, China, the epicenter of the worldwide outbreak. The remaining two were spread from travelers to their spouses.
