The BBC is reporting that 20 people had been taken to hospitals in western Germany after contracting the bug on the U.K.-based River Cruise Line's Lady Anne earlier this week. The site also says that 23 people had been confined to their cabins when they were struck down with the sickness.
Those remaining on the 106-passenger ship will disembark in Boppard, Germany, where it has been moored up.
Lady Anne, which had been on a five-day Rhine cruise, will be professionally cleaned and its next scheduled cruise has been cancelled.
In a statement to the BBC, River Cruise Line said: "Our passengers, crew and staff who are onboard the Lady Anne are now able to get off the ship and doctors have confirmed that they are fit to travel and we are making arrangements for them to return home today.
"We will be arranging for a doctor to accompany our passengers during the journey to Folkestone.
"We would like to again express our gratitude for the excellent work of the German paramedics and offer our apologies to all those directly and indirectly affected."
The term Norovirus actually refers to a series of extremely common and highly contagious viruses that causes gastroenteritis. We tell you all you need to know and bust some of the myths surrounding the bug.
