  HPA | Norovirus | FAQs
Norovirus often causes outbreaks because it is easily spread from one person to another and the virus is able to survive in the environment for many days.
Outbreaks of norovirus are reported frequently in semi-closed institutions such as hospitals, schools, residential and nursing homes and hotels.
Norovirus is not a notifiable disease so reporting is done on a voluntary basis.

 ICCL - Cruise Industry Policies: Norovirus
A common type of gastrointestinal virus called norovirus, sometimes referred to as the "stomach flu," is the second most prevalent illness in the general population behind the common cold.
Norovirus can be transmitted from person to person through direct contact, eating or drinking foods and liquids infected with norovirus, or indirectly from transfer of the virus to surfaces that are then touched by another person.
In most cases of norovirus reported on cruise ships, the CDC has determined that the increased incidents of norovirus were sourced from passengers bringing the illness on board and transmitting it through direct or indirect contact - not from food or water sources.

 Cruise Critic Cruise Planning: Norovirus: What You Need to Know
Norovirus is not a "cruise ship" virus, nor does it limit itself to sea-going vessels.
Norovirus is associated with cruise travel simply because health officials are required to track illnesses on ships (and are not at hotels and resorts); therefore, outbreaks are found and reported more quickly at sea than on land.
Though Norovirus can be passed via contaminated food and water, when it comes to cruise ships it is typically spread through physical contact with ill people or surfaces/objects they may have touched.
