目的了解马鞍山市流感流行动态,为流感的防治提供科学依据。方法统计监测医院流感样病例(ILI)数据,采集部分ILI咽拭子标本,用MDCK细胞进行流感病毒分离,采用血凝抑制实验进行流感病毒型别鉴定。结果马鞍山市2006-2007年共报告流感样病例15904例,流感样病例就诊百分比为6.63%。采样2656例,分离出病毒358株,病毒分离率为13.48%,其中A型H1N1亚型142株、A型H3N2亚型49株、B(Victoria)型72株、B(Yamagata)型96株。结论2006-2007年马鞍山市流感发病呈现冬春季及夏季两个峰,应进一步加强对流感的监测。
Objective To understand the epidemiological trend of influenza in Ma’anshan and to provide a scientific basis for the prevention and treatment of influenza. Methods Statistical data of hospital-like influenza-like illness (ILI) were collected. Some throat swab specimens from ILI were collected, and influenza virus was isolated from MDCK cells. The type of influenza virus was identified by hemagglutination inhibition test. Results A total of 15 904 flu-like cases were reported from 2006 to 2007 in Ma’anshan City, and the percentage of flu-like cases was 6.63%. A total of 2656 samples were collected and 358 viruses were isolated. The virus isolation rate was 13.48%. Among them, 142 strains were type A H1N1, 49 type A H3N2, 72 type B and 96 strains B (Yamagata). Conclusion The incidence of influenza in Ma’anshan City during 2006-2007 showed two peaks in winter, spring and summer, and influenza surveillance should be further strengthened.
