Hawaii has confirmed its first novel coronavirus case, according to state officials at a Friday news conference.
Governor David Ige said the patient is a Hawaii resident who traveled on the Grand Princess cruise ship, which is now in quarantine off the coast of California.
It’s the seventh confirmed case tied to the cruise ship.
Ige said the Hawaiian patient disembarked in Mexico, but officials are aware that the cruise ship also stopped at four Hawaiian ports last month.
The state is examining the manifest of Grand Princess passengers to contact those who stopped in Hawaii, asking that they self-quarantine, he said.
And if you're told to self-quarantine, here's what you need to know.

A resident of a nursing home in Issaquah, Washington tested positive last night for the novel coronavirus, according to Eastside Fire Deputy Chief Rich Burke.
The patient has since been transferred from the facility to a local hospital, and three firefighters who responded to the scene have self-quarantined.
“We worked closely with the Kirkland Fire Department and learned a lot from what they went through,” Burke said.
The Issaquah Nursing & Rehabilitation Center, where the patient was living, posted a message on its website saying it had implemented infection control procedures for staff and residents.
This is the third senior care facility in the past week in Washington state to have a resident diagnosed with coronavirus.
