摘要
目的了解某鞋厂流感暴发的疫情特征和病原体,为制定预防控制措施提供科学依据。方法按2005年广东省卫生厅《广东省流感样病例暴发疫情报告及调查处理工作指引(试行)》进行现场调查和处理。采用胶体金法、RT-PCR方法进行病原学检测。结果共发生217例流感样病例,罹患率为1.05%,其中以第二分厂发病罹患率最高(1.81%)。疫情持续25d,男女发病比例为1∶8,男性罹患率为0.43%,女性罹患率为1.27%,女性发病率高于男性并有统计学意义(χ2=26.8,P<0.01)。15.7%的病例集中在20岁组人群;二分厂生产车间的管理及其他人员发病较精致线上的人员高。实验室分离鉴定为H3亚型病毒。结论根据流行病学调查、临床表现和实验室检测,确定此起流感由H3亚型流感病毒引起。
Objective To find out the epidemic characteristics of influenza and etiology in a shoe manufactory for providing effective measures to control the outbreak. Method Investigation and laboratory tests were conducted according to ＂The Guidelines and Epidemic Situation Reports of Influenza Outbreak in Guangdong Province （ For Trial Implementation）＂ issued by Health Department of Guangdong Province in 2005.

The attack rate was 0. 43% in male, 1.27% in female, and there was significant difference in atack rate between female and male（X2 =26. 8, P 〈0. 01 ）. 15.7% of 217 cases occurred at age group of 20 years old. The attack rate among persons in charge of workshops was higher than the persons working on the sewing lines. The subtype H3 of influenza virus was indentified.
