At least 172 people arriving in California on Sunday aboard a Crown Princess cruise ship are sick with the highly contagious norovirus, the Centers for Disease Control says.

The ship has more than 4,100 people on board returning from a monthlong Pacific cruise. Passengers will be met by CDC staff upon arrival in San Pedro, The Associated Press reported.

At least 14 of the 172 infected are Crown Princess staff, the report said.

Norovirus symptoms include vomiting, diarrhea, fever and body aches. The CDC said most people recover within three days, AP reported.

In a statement, Princess Cruises said the ship would “increase cleaning and disinfection procedures according to their outbreak prevention and response plan,” a local ABC affiliate reported.

“We are sorry this incident has impacted our guests’ vacations and are grateful for their understanding given the circumstances. The health and safety of our crew and guests is our top priority,” the cruise line said.

The CDC said Princess Cruises is consulting with them to ensure the ship is disinfected before it sets sail again Sunday.

In April, 129 people on the same ship contracted norovirus during a seven-day cruise off the California coast, AP reported.
