Abstract

Norovirus is the most commonly reported virus in shellfish related gastroenteritis outbreaks. In March 2013 an investigation was conducted following the receipt of reports of gastroenteritis after the consumption of oysters at private functions in Tasmania. Cases were ascertained through general practitioners, emergency departments, media releases and self-reporting. Of the 306 cases identified in Tasmania, ten 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 oysters 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 consequences of norovirus outbreaks in shellfish, even with rapid identification, trace back and removal of the implicated product from the market.

摘要

诺如病毒是与贝类相关的肠胃炎暴发中报告最为常见的病毒。2013年3月，在收到塔斯马尼亚私人活动中食用牡蛎后出现肠胃炎报告后，开展了一项调查。通过全科医生、急诊科、媒体发布和自我报告来确定病例。在塔斯马尼亚确定的306例病例中，采集了10份粪便标本进行实验室检测，8份诺如病毒（GII.g）呈阳性。最常见的症状是呕吐（87%）、腹泻（85%）、肌痛（82%）和发热（56%）。涉事牡蛎追溯到一个养殖场，从该养殖场收获后在当地和州际进行分销。在全国范围内，从塔斯马尼亚（306例）、维多利亚州（209例）、新南威尔士州（8例）和昆士兰州（2例）共确定了525例病例。本报告强调了贝类中诺如病毒暴发的后果，即使能迅速识别、追溯并将涉事产品从市场上清除。
