It has canceled plans to visit Lisbon, Portugal, as the last leg of its cruise and was to leave later Wednesday for Southampton, England, where the cruise began Saturday, Princess Cruises said in a statement. The vessel arrived in Vigo from Le Havre, France, te AP reports.

The symptoms of the bug - believed to be one called Norovirus - are nausea and diarrhea; they tend to last 24-48 hours. As of Wednesday afternoon, only about 15 people were still ill, the company said.
