目的对深圳市龙岗区2010—2011年流感监测结果进行分析,为流感的预防与控制提供依据。方法采集龙岗区流感监测哨点医院的流感样病例咽拭子样本,提取流感病毒核酸,采用荧光定量PCR进行流感病毒核酸检测。结果 2010年检测流感样病例咽拭子样本368份,检出流感病毒核酸阳性112份,阳性率为30.4%,其中A型流感阳性57份(占50.9%),B型流感阳性55份(49.1%)。2011年检测流感样病例咽拭子样本453份,检出流感病毒核酸阳性209份,阳性率为46.1%,其中A型流感阳性130份(占62.2%),B型流感阳性79份(占37.8%)。2011年流感病毒核酸阳性率高于2010年(P<0.01)。结论深圳市龙岗区2010—2011年流感流行特征有较大变化,开展全年监测对流感的预测预警具有重要意义。
Objective To analyze the influenza surveillance results from 2010 to 2011 in Longgang District of Shenzhen City, and provide the basis for the prevention and control of influenza. Methods Throat swab specimens were collected from influenza-like sentinel hospitals in Longgang District, and influenza virus nucleic acid was extracted. Fluorescent quantitative PCR was used to detect influenza virus nucleic acid. Results A total of 368 swab samples of influenza-like illness were detected in 2010, of which 112 were positive for influenza virus. The positive rate was 30.4%, of which 57 were positive for type A (50.9%) and 55 were positive for type B (49.1 %). In 2011, 453 samples of throat swabs were detected in influenza-like cases, of which 209 were positive for influenza virus. The positive rate was 46.1%, of which 130 were positive for type A (62.2%) and 79 were positive for type B (accounting for 37.8 %). The positive rate of influenza virus nucleic acid in 2011 was higher than that in 2010 (P <0.01). Conclusion The prevalence of influenza in 2010-2011 in Longgang District of Shenzhen Municipality has greatly changed. It is of great significance to carry out annual monitoring on the prediction and forecast of influenza.
