The NORISK project aims to elucidate transmission routes of noroviruses, pathogens generally recognized as a leading cause of foodborne non-bacterial gastroenteritis.These goals will be accomplished by (1) development of detection methods for norovirus in food products, (2) investigation of (foodborne) norovirus outbreaks and (3) investigation of possible zoonotic transmission. Ghent University focuses mainly on development of norovirus detection methodology.
