【摘要】：目的分析2010-2013年度梧州市流感病毒流行特征。方法选择监测点进行流感流行病学和实验室病原学监测。结果 2010-2013年梧州市流感样病例(Influenza-Like Illness,ILI)按月百分率分别为0.93%~1.6%、0.9%~1.14%、1.04%~4.19%、2.03%~3.54%。流感样病例主要集中在5岁以下儿童。2010年检出流感病毒核酸阳性标本125份,阳性率9.87%,其中新甲型H1N1、季节性H3N2和B型流感分别占阳性标本的21.51%、26.41%和55.82%;2011年检出核酸阳性标本92份,阳性率9.48%,新甲型H1N1占优势;2012年检出核酸阳性标本154份,阳性率14.35%,主要型别为B型和季节性H3N2;2013年核酸阳性标本295份,阳性率19.55%,主要型别为新甲型H1N1和B型流感。2010-2013年流感暴发疫情共有8起,在4月、6月、11月、12月发生。结论通过观察门诊流感样病例数的百分比变化,可以大体推测流感活动强弱;对流感各亚型核酸的检测能较准确地反映了流感病毒的流行状况。
[Abstract]:Objective to analyze the epidemic characteristics of influenza virus in Wuzhou City in 2010-2013. Methods Influenza epidemiology and laboratory etiology were monitored at surveillance sites. Results the monthly percentages of Influenza-Like Illnessessi from 2010 to 2013 in Wuzhou City were 0.93and 1.60.0.0.14 and 1.040.4.190.2.033.540.Results the number of flu cases in Wuzhou City from 2010 to 2013 was 0.93% and 1.14%, respectively. The influenza-like cases were mainly collected from 125 positive specimens of influenza virus nucleic acid in children under 5 years of age. The positive rate of influenza virus nucleic acid was 9.87. The positive rate of influenza A H1N1, seasonal H3N2 and influenza B was 21.51%, 26.41% and 55.82% respectively, and 92 positive samples were detected in 2011. The positive rate was 9.48%. In 2012, 154 nucleic acid positive specimens were detected in the new type A H1N1, the positive rate was 14.35, the main types were B type and seasonal H3N 2, and 295 nucleic acid positive specimens were detected in 2013. The positive rate was 19.55%. The main types were new influenza A (H1N1) and influenza B (2010-2013). There were 8 outbreaks in April, June, November and December. Conclusion by observing the percentage change of the number of influenza-like cases in outpatient clinic, the strength of influenza activity can be estimated, and the detection of nucleic acid subtypes of influenza can accurately reflect the epidemic situation of influenza virus.
