目的了解某动物市场从业人员SARS-CoV感染状况,初步探讨其影响因素。方法对广州市某动物市场环境卫生状况进行现场观察,并对市场从业人员进行血清学调查和问卷调查。结果调查共获得有效问卷293份,其中男性209例,女性84例。SARS-CoV抗体阳性率为27.3%,接触动物类别和SARS-CoV感染情况有关,各类人员的抗体阳性率由高到低排列依次为:主营野生畜类者、市场管理部员工、主营家禽家畜类者、主营野生蛇类者和主营冷冻食品类者。另外环境较差的第二、三通道从业人员SARS-CoV抗体阳性率也较高。结论初步发现经营动物的种类是SARS-CoV感染的重要影响因素,动物市场从业人员SARS-CoV感染与环境因素可能也有关系。
