News Summary

• Norovirus (the so-called vomiting bug) is the infection most closely linked to cruise ships.
• Buffet-style dining, shared utensils and many people touching the same surfaces can make it easier for stomach bugs to spread.
• Legionnaires’ disease (a serious lung disease caused by bacteria) shows a different kind of risk.
• It is not usually spread directly from one person to another.
• Instead, people can get infected by breathing in tiny droplets from contaminated water systems, hot tubs or showers.
