The latest norovirus outbreak aboard the Princess Cruises' Crown Princess has infected 172 people, according to the U.S. Centers for Disease Control and Prevention.
At least 158 of 3,009 passengers and 14 of 1,160 crew members came down with the virus aboard the Crown Princess during a 28-day cruise that docked in Los Angeles on Sunday.
This ship had sailed from Los Angeles to Hawaii and Tahiti.
Onboard rapid norovirus testing resulted in positive results of the virus, the CDC investigation update confirmed.
At least 122 of 3,161 passengers and 30 of 1,176 crew members aboard the Crown Princess were sickened on an April sailing, according to the CDC. The federal agency blamed norovirus and E. Coli for the outbreak.
Norovirus is known for being quite contagious. It causes nausea, vomiting and diarrhea and is believed to have infected passengers on a number of cruise ships this year.
It is passed in person-to-person contact and can spread more easily in closed quarters.
