Norovirus Makes a Comeback, Surging on Cruise Ships

The number of norovirus outbreaks on cruise ships in the US has surged this year, with 13 outbreaks recorded so far, the highest since 2012. Experts believe the increase may be due to the soaring demand for cruises and record numbers of passengers. Norovirus is a highly contagious virus that causes acute gastroenteritis, leading to symptoms such as nausea, vomiting, diarrhea, and stomach pain. To prevent the spread of norovirus, experts recommend thorough handwashing with soap and warm water, as hand sanitizers are not effective against the virus. The CDC advises passengers to practice good hygiene, avoid contaminated food, and notify the ship's medical team if they become ill.
