Another cruise ship has returned to its home port early in the wake of an outbreak of gastrointestinal illness.
Princess Cruises' Houston-based Caribbean Princess arrived back in the city late Thursday, more than 24 hours ahead of schedule.
More than 160 of 3,104 passengers on the vessel have fallen ill with a gastrointestinal illness that the cruise line suspects is norovirus -- a highly contagious infection that causes severe vomiting and diarrhea.
The incident comes just days after a massive outbreak of a norovirus-like illness forced an early end to a sailing of Royal Caribbean's Explorer of the Seas. The ship returned to its home port of Bayonne, N.J. on Wednesday -- two days ahead of schedule -- after more than 20% of 3,071 passengers fell ill.
