Norovirus causes an inflammation of the stomach or intestines called acute gastroenteritis, producing stomach pain, nausea and diarrhea, according to the Centers for Disease Control.
Each year, norovirus causes some 21million illnesses, of which 70,000 require hospitalization. It kills about 800 people a year, the CDC says.
The Queen Mary 2, with 2,613 passengers and 1,255 crew members, is now docked in Saint Maarten in the Caribbean, according to ship owner Cunard Line, which is owned by Carnival Corp.
The CDC learned of the illnesses on the QM2 on Christmas Day, and of those on the Emerald Princess last Saturday. Vessels are required to notify the agency when two percent of those on board develop a gastrointestinal illness.
