The Caribbean Princess returned to the Bayport Cruise Terminal in Pasadena late Thursday. Princess Cruises, which owns the ship, says the highly contagious norovirus spread quickly among passengers, forcing a premature end to their voyage.
The company says in a statement that Centers for Disease Control officials will board the ship Friday to ensure thorough sanitation.
The Caribbean Princess left the Pasadena port Jan. 25 bound for the Caribbean with more than 4,200 people aboard. It had been scheduled to return Saturday.
Royal Caribbean's Explorer of the Seas returned to New Jersey on Wednesday after nearly 700 aboard fell sick with the same gastrointestinal illness.
