The federal Centers for Disease Control and Prevention recently reported that a norovirus was what sickened 124 people on the cruise ship Veendam in June.
The CDC says 12 of 556 crew members and 112 of 1,313 passengers got sick during the Holland America Line cruise ship's voyage from Vancouver through Alaska.
A report says most sick people had diarrhea and vomiting.
According to the Juneau Empire, records show the Veendam had two norovirus outbreaks in 2004, three in 2005 and one in 2006.
Noroviruses cause diarrhea and vomiting. Most people recover after a day or two. People get sick by eating food, touching surfaces or contacting people contaminated with the virus.
