【摘要】：目的了解本市职业暴露人群高致病性禽流感病毒的感染状况和该病毒在环境中的分布情况,提高本市监测水平,及时发现人禽流感疫情。方法对阳泉市城区、矿区、郊区、平定县、盂县5个县区职业暴露人群抽样调查,问卷调查的同时采集调查对象的咽拭子和环境标本。荧光定量PCR对咽拭子和环境标本进行A型流感核酸检测,A型流感病毒核酸阳性标本进一步行亚型检测。结果监测职业暴露人群251名,54.18%的从业者经常接触死禽,接触死禽人群中67.65%没有任何防护措施,所有职业暴露人群A型流感核酸检测阴性。50份环境标本中在活禽市场检出H9亚型禽流感2份,阳性率为4%。结论阳泉市职业暴露人群未发现A型流感病毒隐性感染,活禽市场存在H9亚型禽流感,应加强对活禽市场的科学管理。
[Abstract]:Objective to investigate the infection status of highly pathogenic avian influenza virus in occupational exposed population and its distribution in the environment, to improve the surveillance level and to detect human avian influenza epidemic in time. A sampling survey of occupational exposure population in five counties and regions of Pingding County and Yu County, The throat swabs and environmental samples of the subjects were collected simultaneously by questionnaire survey. Fluorescence quantitative PCR was used to detect influenza A nucleic acid and influenza A virus nucleic acid positive samples. The results showed that the positive samples of influenza A virus nucleic acid were further detected by fluorescence quantitative PCR. 54.18% of the 251 workers who were exposed to occupational exposure were in frequent contact with dead birds. No protective measures were taken in 67.65% of the population exposed to dead poultry, and 2 of the 50 negative samples of influenza A nucleic acid from all occupational exposed people were detected in live poultry markets. Conclusion there is no latent infection of influenza A virus in occupational exposed population in Yangquan city, and H9 subtype avian influenza exists in live poultry market, so the scientific management of live poultry market should be strengthened.
