7. Interesting. I hadn't heard of it, probably assumed those outbreaks

were either food poisoning or norovirus. But the Google tells me otherwise.

The human caliciviruses (HuCV) are the most common cause of acute gastroenteritis outbreaks in humans, and a common cause of sporadic cases of acute gastroenteritis with vomiting, abdominal cramps, diarrhoea, headache and fever among both children and adults [10,11]. Their role as agents of gastroenteric diseases had long been unrecognized and under-appreciated because diagnostic tools were not commonly available or used. The application of new molecular diagnostic methods has shown caliciviruses to be the most common cause of acute gastroenteritis outbreaks in the USA [11] and in Europe [12].
