The ship underwent a thorough cleaning and it sailed Sunday evening, Nov. 16 at 10p.m. on its next voyage to the Mexican Riviera.
The month-long cruise from California had made stops in Hawaii and Tahiti before people began falling ill, according to the Reuters news service.
"Over the last few days, the ship began seeing an increased number of gastrointestinal illnesses, caused by norovirus," Carnival spokeswoman Susan Lomax told Reuters.
"In response, we have enacted our stringent disinfecting protocols developed in conjunction" with the U.S. Centers for Disease Control and Prevention," she said.
There were more than 4,000 passengers and crew aboard the vessel, Reuters said.
Norovirus is a mild gastrointestinal illness characterized by nausea, vomiting and diarrhea that persist for three or four days, the news service said.
But the outbreak has raised some concerns since it is the second outbreak on the Crown Princess this year.
In April, more than 100 people aboard ship were sickened on a similar cruise.
More than a dozen cruise lines leaving from U.S. ports have reported outbreaks of the norovirus in the past few years.
Norovirus is the most common of gastrointestinal viruses and typically strikes people confined to a small area with limited access to handwashing facilities.
There are an estimated 20 million cases of norovirus in the U.S. each year, Reuters said.
The Crown Princess is scheduled to leave Sunday night on a cruise to the Mexican Riviera.
