A BBC article shows just how easy it is for norovirus to spread through a cruise ship.
According to the article, one passenger boarded Fred Olsen's Balmoral on Saturday, and she was detected at that point to have norovirus. She was confined to her cabin by the medical staff. The woman did not stay in her cabin as she was requested to do, and now, by Tuesday, 91 passengers have the virus.
Kind of makes you sick, doesn't it?
