目的:探讨2011年衢州市流感流行规律,为做好流感预防控制工作提供科学依据。方法:对本市2011年各流感监测哨点送检的流感样病例标本,进行流感病毒分离培养,用“O”型人血红细胞作微量血凝试验(HA)、血凝抑制试验(HI)进行鉴定。结果:2011年共检测流感样病例标本397份,分离出流感病毒23株,其中,流感流行主要发生在1月-3月及10月-12月;男女比例相似,年龄以30岁～39岁为高发人群(11.84%)。结论:2011年衢州市流感流行出现2个高峰期,分布于冬春季节,其中,甲型H1N1型成为当年高检出率的优势流行株,应加强防范对甲型H1N1流感毒株可能造成的流行或暴发。
Objective: To explore the prevalence of influenza in Quzhou in 2011 and provide a scientific basis for the prevention and control of influenza. Methods: Influenza-like specimens were collected from all the influenza surveillance sentinel sites in the city in 2011. Influenza virus was isolated and cultured. The “O” type human erythrocytes were used for micro-coagulation test (HA), hemagglutination inhibition test ) For identification. Results: In 2011, 397 samples of influenza-like illness were detected and 23 strains of influenza virus were isolated. Among them, the prevalence of influenza mainly occurred in January-March and October-December; the proportions of men and women were similar, and the age ranged from 30 to 39 years For the high incidence of the crowd (11.84%). Conclusion: There were two peak periods of influenza in Quzhou in 2011, which were distributed in winter and spring. Among them, type A H1N1 became the prevalent epidemic strain with high detection rate in that year, and should be strengthened to prevent the possible impact on influenza A (H1N1) virus strains Popular or outbreak.
