[目的]了解山东省流感流行特点,掌握流感病毒优势毒株的变异动态,为及早发现和控制疫情提供科学依据。[方法]2007年10月至2008年3月,山东省各哨点医院报告的门诊流感样病例(ILI)和门急诊病例就诊总数统计资料和部分医院采集的ILI鼻咽拭子标本流感病毒检测资料进行分析。[结果]监测期间,全省52家哨点医院合计,内科(儿内科)门诊病例1 267 783例,其中ILI 23 023例,占1.82%。ILI%,2007年10月至2008年3月分别为1.79%、1.68%、1.87%、2.18%、1.88%、1.50%(P<0.05);55.72%的ILI集中在5岁以下年龄组;不同地区ILI就诊百分比不同,滨州市、潍坊市、泰安市分别为5.30%、3.88%、3.37%,菏泽市、临沂市、德州市分别为0.17%、0.34%、0.53%,其他11个市为0.56%~2.97%。合计检测ILI标本941份,检出流感病毒246株(H1N1型3株,H3N2型114株,B型124株,H3N2型和B型混合感染5株),阳性率为26.14%。流感病毒检测阳性率,各月分别为18.60%、15.57%、28.81%、36.20%、17.43%、17.46%(P<0.05)。[结论]2007~2008年度山东ILI疫情平稳,以H3N2和B型为优势流行株。
[Objective] To understand the epidemic characteristics of influenza in Shandong Province, grasp the variation of the dominant strains of influenza virus and provide a scientific basis for early detection and control of the outbreak. [Methods] From October 2007 to March 2008, statistics of outpatient influenza-like illness (ILI) and outpatient and emergency department reported cases in all sentinel hospitals in Shandong Province and ILI nasopharyngeal swab specimens collected from some hospitals were detected by influenza virus Data analysis. [Results] During the monitoring period, there were 1 267 783 cases of internal medicine (pediatric internal medicine) out of 52 sentinel hospitals in the province, of which ILI 02 023 cases accounted for 1.82%. ILI%, respectively, 1.79%, 1.68%, 1.87%, 2.18%, 1.88%, 1.50% (P <0.05) from October 2007 to March 2008; 55.72% of ILI were concentrated in the age group under 5 years; The percentage of ILI visits in different regions is different, with Binzhou, Weifang and Tai’an at 5.30%, 3.88% and 3.37% respectively, and Heze, Linyi and Dezhou at 0.17%, 0.34% and 0.53% respectively, and 0.5% at 11 other cities % ~ 2.97%. A total of 941 ILI samples were detected, of which 246 were influenza viruses (3 strains of H1N1, 114 of H3N2, 124 of B, 5 of H3N2 and B) with a positive rate of 26.14%. The positive rate of influenza virus was 18.60%, 15.57%, 28.81%, 36.20%, 17.43% and 17.46% respectively (P <0.05). [Conclusion] The epidemic situation of ILI in Shandong from 2007 to 2008 was stable, and H3N2 and B strains were dominant epidemic strains.
