This is a wonderfully comprehensive study about how norovirus is transmitted. Way to investigators from the CDC, New Zealand and The Netherlands! Norovirus is responsible for a huge number of gastroenteritis cases and the main reason I won't take a cruise!
What was really interesting to me is the 14% value. 14% of norovirus outbreaks are due to contaminated food. This seems like a really big value, especially when you consider that this is a preventable transmission route! I hope 2015 sees fewer cases as more people become aware of how to stop spreading it!
