太原市不同人群SARS血清流行病学调查

Seroepidemiological study on severe respiratory syndrome among different population in Taiyuan

摘要

摘要:
目的分析山西省太原市严重急性呼吸系统综合征(SARS)患者及其密切接触者和社区人群中血清SARS抗体水平。
方法采用ELISA方法检测3组人群的SARS特异性抗体, 并进行分析比较。
结果 SARS患者、密切接触者和社区健康人群的SARS冠状病毒(SARS-CoV)抗体阳性率分别为5 2.08%, 4.63%和1.88%, 3组人群比较差异有统计学意义; 3组人群中不同年龄组及性别间抗体阳性率差异无统计学意义。在密切接触者既往各类接触史中, 除“接触时有无洗手”与血清SARS-CoV抗体阳性有关外, 未发现其它有关因素。
结论太原SARS病例存在过度诊断现象, 密切接触者和普通人群中可能存在SARS的隐性感染。

Abstract:
Objective To analyze the SARS-CoV antibody level among patients with severe acute respiratory syndrome (SARS), close contactors with suspected SARS and community-based population in Taiyuan, Shanxi Province.
Methods ELISA method was used to detect the SARS-CoV antibody level among patients with severe acute respiratory syndrome (SARS), close contactor with SARS and community-based population followed a comparative analysis.
Results Positive rate of SARS patients, close contactor and general population was 52.08%, 4.63% and 1.88% respectively.No difference rate of SARS-CoV Ab was found between male and female and among difference age groups.No relationship was found between SARS-CoV Ab and history of contacting factors except the item "washing hands after contacting suspected SARS patients".
