目的 探讨动物市场从业人员SARS冠状病毒(CoV)感染的可疑危险因素。方法 在对广州市3家大型野生动物市场从业人员进行SARS-CoV抗体检测的基础上,采用自行设计调查表进行SARS-CoV感染的危险因素调查,采用单因素和多因素logistic回归分析方法分析资料。结果经单因素logistic回归分析发现,经营其他畜类(猫、狗)、野生畜类(狸、山猪、黄猄)、其他野生类(蝙蝠、巨蜥、穿山甲等)、水产类(甲鱼、龟、鳗鱼、蛙等)动物、采购销售等是SARS-CoV感染的相关因素;经多因素logistic回归分析发现有意义的因素是经营野生畜类(狸、山猪、黄猄)(P<0.001)和经营家禽(鸡、鸭、鹅、鸽子)(P=0.04),OR值分别为12.28、0.41。结论 接触狸类动物是该从业人员感染SARS-CoV的主要危险因素。
Objective To investigate suspicious risk factors of SARS-CoV infection in animal market. Methods Based on the detection of SARS-CoV antibodies in three large-scale wildlife markets in Guangzhou, the risk factors of SARS-CoV infection were investigated by self-designed questionnaire. The data were analyzed by single factor and multivariate logistic regression analysis . Results According to the univariate logistic regression analysis, it was found that other wild animals (cats, dogs), wild animals (raccoon, wild boar, yellow catfish), other wild species (bats, monitor lizards, Eel, frog, etc.) animals, procurement and sales were the related factors of SARS-CoV infection. The significant factors found by multivariate logistic regression analysis were that the management of wild animals (raccoon, wild boar, yellow grub) (P <0.001) Poultry (chickens, ducks, geese and pigeons) (P = 0.04), with OR values of 12.28 and 0.41 respectively. Conclusion Exposure of beaver animals is a major risk factor for SARS-CoV infection among practitioners.
