Almost 2,000 people have been infected with norovirus on cruise ships this year, meaning there are more norovirus cases at sea halfway through 2023 than there were in 2022.
A highly contagious stomach bug is creeping across Canada, wreaking gastrointestinal distress. Norovirus, like the Norwalk strain, is starting to cause major outbreaks this season bringing with it unpleasant symptoms linked to stomach flu, fever and fatigue. Infections usually spread in the colder months through contaminated food and can last for several days. If you or a friend feel the onset of an upset stomach, here's what you should keep in mind.
The norovirus symptoms typically last between 24 and 72 hours, but if they linger longer than that, you should seek medical attention right away, especially if you start passing blood in your stools.
