At least 70 people on a month-long cruise from Singapore to Los Angeles were stricken with norovirus when an outbreak swept through the massive cruise liner.

Of the 1,822 passengers onboard the Coral Princess, 55 came down with the misery-inducing illness — while 15 of the 907 crew also got sick, according to the Centers for Disease Control and Prevention (CDC).

Most suffered “diarrhea and vomiting,” the CDC said.

The ship, which heaved off on Oct. 17, has since implemented more stringent “cleaning and disinfection procedures according to their outbreak prevention and response plan,” the federal agency said.

The CDC’s Vessel Sanitation Program is monitoring the outbreak remotely.

The federal agency requires ships to inform it of such outbreaks when 3% or more of guests and crew members experience symptoms, according to Cruise Hive.

The sickness erupted sometime around Nov. 9, or eight days before the ship was set to port in its California destination, the CDC said.

The agency has logged 11 different outbreaks of gastrointestinal illness on cruise ships this year — and norovirus caused all but three, the USA Today said.

The Coral Princess, which was refurbished in January 2019, is meant to carry a total of just under 3,000 people, including guests and crew.

The 203-foot tall cruiser — which stands as high as a 20-story building and is nearly as long as the Chrysler Building is high — has 16 decks, 1,000 guest cabins and weighs more than 91,000 tons, according to the Princess website.
