Outbreak details

Norovirus is a highly contagious virus that causes gastroenteritis, typically characterized by symptoms such as nausea, vomiting, diarrhea, and stomach pain.

The virus spreads easily in crowded environments, such as cruise ships, through direct contact with an infected person or by touching contaminated surfaces and then touching the mouth.

While the specific location of the ship and the total number of confirmed cases have not been further detailed, the scale of the illness has led to significant disruption on board.

Industry response to norovirus

Cruise lines typically implement strict sanitation protocols when a norovirus outbreak is detected. These measures generally include the use of medical-grade disinfectants on high-touch surfaces and the isolation of symptomatic passengers in their cabins to limit further transmission.

Princess Cruises Limited is expected to follow standard health and safety guidelines to contain the spread of the virus and ensure the wellbeing of those remaining on board.
