摘要：Norovirus is the most commonly reported virus in shellfish related gastroenteritis outbreaks. In March 2013 an investigation was conducted fol-lowing the receipt of reports of gastroenteritis after the consumption of oysters at private functions in Tasmania. Cases were ascertained through gen-eral practitioners, emergency departments, media releases and self-reporting. Of the 306 cases identified in Tasmania, 10 faecal specimens were collected for laboratory testing and eight were positive for norovirus (GII.g). The most common symptoms were vomiting (87%), diarrhoea (85%), myalgia (82%) and fever (56%). The implicated oys-ters were traced to a single lease from which they were harvested and distributed locally and interstate. Nationally 525 cases were identified from Tasmania (306), Victoria (209), New South Wales (8) and Queensland (2). This report highlights the conse-quences of norovirus outbreaks in shellfish, even with rapid identification, trace back and removal of the implicated product from the market
