目的 了解广州市野生动物市场从业人员SARS冠状病毒感染状况。方法 对 3家野生动物市场部分从业人员进行SARS冠状病毒IgG抗体血清学检测并回顾性调查急性呼吸道感染症状。结果 6 35名从业人员中 ,SARS冠状病毒抗体检出率为 16 6 9%。 3家市场从业人员抗体检出率存在着差异 ,主营野生畜类动物的甲市场为 2 5 6 1% ,明显高于分别主营禽类、蛇类的乙市场和丙市场 (7 5 0 %和 6 80 % ) ;只经营果子狸者抗体检出率为 5 8 5 4 % ,明显高于只经营蛇类者的9 4 6 %。甲市场内 ,主营野生畜类者、市场管理者、从业人员子女、主营家禽家畜类者、主营蛇类者及经营冷冻类食品者等 6类人员随着接触野生畜类动物机会的减少 ,抗体检出率下降 ,依次为5 9 34%、2 0 5 9%、16 0 0 %、15 2 2 %、10 4 0 %和 9 6 8%。在SARS流行期间 ,有急性呼吸道感染症状者抗体检出率为 30 70 % ,高于无症状者的 2 0 0 8% ;抗体阳性者急性呼吸道感染症状发生率为4 9 2 8% ,高于阴性者的 30 35 %。结论 动物市场人员SARS冠状病毒感染可能与野生畜类动物 ,特别是果子狸有密切关系。在SARS流行期间 ,不排除存在着部分从业人员曾感染人SARS冠状病毒并发病 ,但由于临床表现不明显而被忽略的可能性
Objective To understand the status of SARS-CoV infection in Guangzhou wild animal market practitioners. Methods The SARS coronavirus IgG serological tests were conducted on some employees in three wild animal markets and the symptoms of acute respiratory infection were retrospectively investigated. Results Among 635 employees, the detection rate of SARS coronavirus was 16 6%. There was a difference in the detection rate of antibodies among the three market practitioners. The market area of main wild animals was 2561%, significantly higher than the market shares of B and C in the main poultry and snakes (75% and 6 80%). The detection rate of antibodies against civet cats was only 58.54%, significantly higher than that of snakes operating only to snakes. Within the A market, there are 6 categories of people mainly engaged in wild animals, market managers, employees and children, the main poultry livestock people, the main snakes and the operators of frozen foods. With the reduction of opportunities for exposure to wild animals and animals, The detection rate of antibodies decreased in the order of 5 9 34%, 25 9%, 16 0 0%, 15 2 2%, 10 4 0% and 9 6 8%. During the SARS epidemic, the detection rate of antibodies in patients with acute respiratory infections was 30 70%, which was higher than that of asymptomatic subjects 280.0%. The incidence of acute respiratory infections in antibody positive patients was 49.8% Negative persons 30 35%. Conclusion SARS coronavirus infection in animal markets may be closely related to wild animals, especially civets. During the SARS epidemic, it is not ruled out that there is a possibility that some employees have been infected with the human SARS coronavirus and have been neglected because of their poor clinical manifestations
