目的分析2009-2012年石嘴山市流行性感冒监测结果,了解其流行趋势及病毒优势株的变化,为防控提供科学依据。方法通过流行性感冒监测信息系统计算哨点医院流感样病例就诊比例,并采集病例标本进行病原学检测,通过疾病监测信息报告管理系统统计流感病例报告例数进行综合分析。结果石嘴山市流行性感冒毒株以A型为主,A(H1N1)亚型和A(H3N2)亚型同时存在,交替成为优势株,B型隔年出现,与A型共存。结论应加强流感监测,分析流行性感冒病毒优势毒株,以便预防控制流感的流行。
Objective To analyze the surveillance results of influenza in Shizuishan City from 2009 to 2012, understand the epidemic trend and the variation of dominant virus strains, and provide a scientific basis for prevention and control. Methods The proportion of flu-like cases in sentinel hospitals was calculated through the influenza surveillance information system, and pathological tests were performed on the samples collected from the sentinel hospitals. A comprehensive analysis was made on the number of cases reported by the system of influenza surveillance information reporting and management system. Results The strains of influenza A in Shizuishan were mainly A type. A (H1N1) subtype and A (H3N2) subtype existed simultaneously and became dominant strains alternately. Type B coexisted with type A every other year. Conclusion Influenza surveillance should be strengthened to analyze the dominant strains of influenza virus in order to prevent and control the prevalence of influenza.
