目的通过分析1起学校甲型H1N1流感爆发疫情的发现和处置情况,总结防控经验,为控制学校甲型H1N1流感爆发疫情提供参考。方法通过流行病学调查,对这次甲型H1N1流感暴发学校的所有病例进行调查,并对部分病例采集咽拭子标本,采用RT-PCR检测甲型H1N1流感病毒核酸。结果 2013年12月27至2014年1月26日,该校共累计报告流感样病例24例,罹患率为2.37%。病例全部为学生,病例主要集中在二年级。病例均为轻症表现,未出现大规模暴发。采集8例流感样病例的咽拭子标本进行检测,结果显示,5份标本新甲1型流感病毒核酸呈阳性。结论此次为一起甲型H1N1流感爆发疫情,及早报告疫情、落实隔离、通风、接种流感疫苗等综合防控措施是控制甲流疫情的关键。
Objective To analyze the detection and treatment of an outbreak of H1N1 influenza in schools, summarize the prevention and control experience, and provide reference for controlling the outbreak of influenza A (H1N1) in schools. Methods Through epidemiological investigation, all the cases of influenza A (H1N1) outbreak schools were investigated. In some cases, throat swab specimens were collected and the nucleic acids of the H1N1 influenza virus were detected by RT-PCR. Results From December 27, 2013 to January 26, 2014, a total of 24 cases of flu-like illness were reported in the school with an attack rate of 2.37%. All cases are students, the cases are mainly concentrated in the second grade. Cases were mild manifestations, did not appear large-scale outbreaks. Throat swab samples from 8 cases of influenza-like illness were collected and tested. The results showed that 5 samples of the new influenza A virus nucleic acid were positive. Conclusions This is the key to controlling the outbreak of Influenza A (H1N1) outbreak with an outbreak of H1N1, early reporting of the outbreak, and implementing comprehensive prevention and control measures such as isolation, ventilation and influenza vaccination.
