Two vaccinated passengers and one unvaccinated crew member tested positive for COVID-19 aboard an American Cruise Lines Alaska cruise.

The 162-guest, 62-crew American Constellation – which was one of the first ships to resume cruising in the Alaska – initially departed on a 10-night sailing from Juneau, Alaska on July 4, USA Today reported. The positive COVID-19 cases were recorded five days later while the cruise was in Petersburg, Alaska.

The three COVID-19-positive passengers and their “close contacts” stayed in Petersburg to quarantine – according to a press release from Juneau, Alaska’s government – while the ship then returned to its homeport on July 10, four days early.

All guests and the majority of the crew aboard the ship were vaccinated. Unvaccinated crew must stay quarantined on the ship as it continues to stay in Juneau until July 20.

American Cruise Lines “strongly recommends the COVID-19 vaccine for all eligible guests,” but vaccination is required for its 2021 Alaska cruises, according to the cruise line’s website. All guests must also be tested for the virus as part of the cruise line’s boarding process.

The “small-ship” cruise line has since canceled what would’ve been the ship’s next cruise on July 14 “out of an abundance of caution,” the cruise line told Insider in an email statement on Monday.

“American Cruise Lines has implemented its COVID-19 Response Plan in Alaska and is coordinating with state and local health officials following the detection of COVID-19 on board,” the cruise line said.

So far, American Cruise Lines has shuttled over 10,000 passengers on 130 sailings since it resumed sailings in March. The three positive cases aboard the American Constellation are the cruise line’s first COVID-19 incidents since its resumption of operations.

Cruise lines like Celebrity Cruises and MSC Cruises have also recently reported positive COVID-19 cases amid the worldwide resumption of cruising.
