HONOLULU (AP) — Anyone flying to Hawaii will be required to have a negative COVID-19 test result prior to their departure for the state, with the new rule going into effect two days before Thanksgiving, Gov. David Ige announced Thursday.

Until now, passengers flying to the islands using a pre-travel testing program were permitted to arrive and then upload their negative test results to a state database, allowing them to skip two weeks of quarantine.

However, some travelers who arrived in Hawaii without their test results wound up later testing positive. That, in part, prompted the rule change, Ige said at a news conference,

The new program goes into effect Tuesday, just ahead of the holiday. The Wednesday before Thanksgiving is traditionally one of the busiest travel days of the year. The Centers for Disease Control has urged people not to travel this year because of a surge in coronavirus cases nationwide.

To bypass the 14-day quarantine, travelers must have the correct type of COVID-19 negative test results from one of the state's trusted testing partners, Ige said.

“If test results are not available before boarding the final leg of their trip, the traveller must quarantine for 14 days or the length of the stay, whichever runs shorter," he said.

Those who arrive without having their negative test results before departure will not be able to skip quarantine, even if their negative results become available shortly after they arrive.

Passenger have always had the option to not get tested at all and quarantine in their hotel rooms or homes upon arrival. Travelers will continue to have that option.

The rules apply to anyone flying to Hawaii from the U.S. mainland or Japan, both of which have pre-testing programs in place. Ige also said passengers from Canada will soon have the option to get pre-tested and come to Hawaii.

For most people, the coronavirus causes mild or moderate symptoms that clear up within weeks. But for others, especially older adults and people with existing health problems, the virus can cause severe symptoms and be fatal. The vast majority of people recover.
