目的对2010年深圳市流感监测结果进行分析,了解流感的流行趋势,为流感防治提供科学依据。方法收集全市31家监测单位的流感样病例数据、病原学检测结果和暴发疫情资料进行分析。结果 2010年深圳市的流感样病例百分比(ILI%)为5.43%。2010年全市共采集日常监测ILI咽拭标本4031份,分离出445株流感病毒,阳性率为11.0%,其中14株季节性H1N1亚型(3.1%),42株季节性H3N2亚型(9.4%),171株甲型H1N1亚型(38.4%),213株B(Victoria,47.9%)亚型,5株B(Yamagata,1.1%)亚型。2010年全市报告了89起ILI暴发疫情,发病总人数741人,流感PCR检测阳性79起,其中季节性甲型6起(6.8%),乙型67起(75.3%),甲型H1N1流感6起(6.8%)。结论 2010年深圳市流感活动较低,未出现明显的高峰。
Objective To analyze the results of influenza surveillance in Shenzhen in 2010 to understand the epidemic trend of influenza and provide a scientific basis for the prevention and treatment of influenza. Methods A total of 31 surveillance units in the city were collected for influenza-like illness data, pathogen test results and outbreak data. Results The percentage of flu-like cases in Shenzhen in 2010 (ILI%) was 5.43%. In 2010, 4031 ILI pharyngeal swabs were routinely collected in the city, 445 influenza viruses were isolated, the positive rate was 11.0%, including 14 seasonal H1N1 subtypes (3.1%), 42 seasonal H3N2 subtypes (9.4% ), 171 strains of type A H1N1 (38.4%), 213 strains of B (Victoria, 47.9%) and 5 strains of B (Yamagata, 1.1%). In 2010, 89 ILI outbreaks were reported in the city, with a total incidence of 741 people and 79 positive influenza PCR tests, of which seasonal influenza A (6) (6.8%), type B (75.3%), type A H1N1 influenza 6 From (6.8%). Conclusion In 2010, influenza activity in Shenzhen was relatively low with no apparent peak.
