【摘要】 目的 :对四川省 1999～ 2 0 0 1年流感监测情况进行分析 ,以便进一步搞好流感监测工作 ,及时制定防治措施 ,对今后的流感流行更能作出精确的预测预报。方法 :1流行病学监测 :1999、 2 0 0 0年及 2 0 0 1年分别选择一所综合医院及一所综合医院和一所儿童医院作哨点常年监测 ,收集每日流感样病人数与门诊病人总数。 2病原学监测 :1999、 2 0 0 0年选择省人民医院、成都市儿童专科医院 ;2 0 0 1年选择青羊区人民医院和成都市儿童专科医院为监测点 ,采集每日流感样病例。用鸡胚分离、 MDCK细胞培养、血凝实验及血凝抑制实验。结果 :1999、 2 0 0 0年全年呼吸道病人与门诊病人总数的比例分别为73 .3 9% (42 484/ 5 7885 )、 80 .94% (45 42 3 / 5 62 0 4)。 2 0 0 1年全年流感样病人与门诊病人总数的比例为 2 0 .0 2 % (2 3 977/95 847)。 1999～ 2 0 0 1年共采集流感样病人标本 1488人份 ,共分离出流感病毒株 10 1株 ,乙型 88株 ,占 87.13 %。甲 3型 2株 ,占 1.98%。甲 1型 11株 ,占 10 .89%。结论 :近三年流感发病率较低 ,引起我省流感的毒株以乙型为主 ,B/四川 / 3 79/99为 WHO及国家代表株更多还原

【Abstract】 Objective:To analyse influenza surveillance activity from 1999 to 2001 in Sichuan province so as to enhance influenza surveillance,formulate preventive policy and forecast epidemics of influenza in the future.Methods:(1)The surveillance of epidemiology.A synthesize hospital was selected and collected all respiratory cases and patients in outpatient everyday as sentry post from 1999 to 2000,a synthesize and children hospital are regard as sentry post in 2001.(2)All samples of suspected influenza cases were collected from Sichuan provincial hospital and Chengdu municipality children hospital between 1999 and 2000,Qing Yang District people’s hospital and Chengdu municipality children hospital in 2001.All specimens were processed in chick embryos and MDCK cell culture and identified using the haemagglutination test(HA) and haemagglutination inhibition test(HI).Results:Rotio respiratory cases in outpatients is 73 39%(42484/57885) and 80 94%(45423/56204) respectively,during 1999～2000 and 20 02%(23977/95847) in 2001.Totally 1488 samples as like influenza case were collected and 101 strains belong to type B(87 13%),2 strains of A3(H3N2) subtype(1 98%) and 11 strains of A1(H1N1) subtype(10 89%) respectively.更多还原
