Nearly 175 passengers and crew members aboard a Princess Cruises ship are ill with the Norovirus, according to the Centers for Disease Control and Prevention. The Crown Princess ship docked in San Pedro on Sunday following the outbreak of the gastrointestinal virus. The cruise was sailing from Tahiti to Los Angeles when an increasing number of Norovirus cases began to appear. This latest outbreak of the Norovirus is the second to hit Princess Cruises this year.
