After battling outbreaks of norovirus for years, it seems that the cruise industry is finally getting a handle on controlling the illness.
Norovirus outbreaks have sickened up to 700 cruise ship passengers at a time, leaving them with symptoms including extreme nausea, vomiting, and diarrhea. The illness is most often spread by contact with fecal matter but has also been shown to become airborne in certain situations.
A recent report by USA Today cites a Centers for Disease Control and Prevention report which found that in 2018 cruise ships experienced the fewest outbreaks sin 2001.
The report goes on to say that in the early 2000s cruise ships routinely reported over 20 outbreaks per year. In contrast, 10 outbreaks were reported in 2018.
