Norovirus outbreaks linked to 2 cruise ships with over 150 infected
A total of 161 passengers have reported falling ill during voyages on Princess Cruises' Sapphire Princess and Royal Caribbean International's Radiance of the Seas
The Centers for Disease Control and Prevention are investigating two seemingly separate outbreaks of Norovirus linked to U.S. cruise ships.
Cases have been linked to Princess Cruises' Sapphire Princess and Royal Caribbean International's Radiance of the Seas.
The CDC's Vessel Sanitation Program (VSP) is tracking the "very contagious" outbreaks following reports of passengers in distress.

Approximately 67 out of 1,993 passengers on the Radiance of the Seas reported falling ill during its voyage from Tampa to Los Angeles between Apr. 8 and 22. An additional two crew members also reported illness.
The predominant symptoms reported from those affected by the Norovirus were diarrhea and vomiting.

"Norovirus is a very contagious virus that causes vomiting and diarrhea. Anyone can get infected and sick with Norovirus," the CDC states on its website. "Norovirus is sometimes called the 'stomach flu' or 'stomach bug.' However, norovirus illness is not related to the flu, which is caused by influenza virus."
One of the biggest health risks posed by Norovirus infection is dehydration — the CDC recommends those infected drink plenty of liquids to aid recovering.
The CDC's Vessel Sanitation Program requires cruise lines to report and document cases of illness on their ships in order to facilitate coordinated responses in case of emergency.
