The US Centers for Disease Control and Prevention said a Norovirus outbreak sickened more than 150 cruise guests on a recent sailing of the Celebrity Summit.
It happened during a recent cruise which ended on May 25.
A total of 152 passengers and 25 crew were sick.
The virus spread rapidly with symptoms such as diarrhea, vomiting and headaches.
In its report, the CDC praised the actions of the ship’s crew in dealing with the outbreak and sick passengers.
There have been several major gastrointestinal outbreaks on cruise ships so far this year.
Norovirus is usually spread through contaminated food and water, or touching contaminated surfaces.
According to the CDC, Norovirus is a ‘very contagious virus that causes vomiting and diarrhea.’
There are millions of Norovirus cases reported annually in the US each year.
