2011年楚雄州禽流感职业人群和环境监测结果分析

Avian Influenza Surveillance Analysis in Occupational Exposed Population and Evironment in Chuxiong State in 2011

目的了解云南省禽流感职业暴露人群及外环境禽流感病毒H5、H9感染状况.方法采集与禽类动物有接触史的职业人群血清标本400份,采用马红细胞血凝抑制试验检测H5N1流感抗体;采集外环境480份标本,用PCR法检测FluA、AH5和AH9及AN1和AN2亚型.结果 400份职业人群血清标本检测结果均为阴性;480份外环境标本检出FluA阳性9份(阳性率1.88%);AH5亚型阳性3份(0.63%),AH9亚型阳性5份(1.04%).结论云南省所监测的活禽市场存在禽流感病毒,职业暴露人群应做好个人防护,减少感染机会.

Objective To understand the pollution of avian influenza in occupational exposed population and external environment of Yunnan. Methods Total of 400 specimens from occupational exposed population were detected by horse erythrocyte HI for H5N 1 antibodies to influenza. Total of 480 environment specimens were detected by PCR assay of FluA, AH5, AH9, AN1 and AN2 subtypes. Results 400 specimens from occupational exposed population test results were negative. 9 specimens were positive to FluA 9 （posit!ve rate 1.88% ） , AH5 subtype positive 3 （ 0.63% ） , AH9 subtype positive 5 （ 1.04% ） of all external environment specimens. Conclusions Part of the live bird markets are polluted by high pathogenic avian influenza in Yunnan province, and occupational exposed population should take personal protective measures to reduce the infection opportunities.
