目的:了解上海奉贤区2010年流感流行的特点,为本地区流感预防控制工作提供科学依据。方法:采用Realtime PCR方法对哨点医院采集的流感样病例进行流感核酸检测。结果:2010年共检测流感样鼻咽拭子标本711份,流感病毒核酸阳性131份,阳性检出率为18.42%。其中检出季节性H11份,占0.14%;季节性H315份,占2.11%;B型流感98份,占13.78%,新甲型H1N117份,占2.39%。1月-3月检出率最高为34.23%,5岁～9岁年龄组阳性率最高,占34.35%。结论:监测显示2010年上海市奉贤区流感主要流行株为B型,流感流行呈冬春季高发的特点,5岁～9岁年龄组为高发人群。
Objective: To understand the characteristics of the epidemic of influenza in Fengxian District in 2010 and to provide a scientific basis for the prevention and control of influenza in this area. Methods: Real-time PCR was used to detect influenza nucleic acid in influenza-like cases collected from sentinel hospitals. Results: In 2010, 711 samples of nasopharyngeal swab samples were detected, and 131 were positive for influenza virus nucleic acid. The positive rate was 18.42%. Among them, 11 were seasonal H11, accounting for 0.14%; seasonal H315, accounting for 2.11%; 98 influenza B, accounting for 13.78%; and H1N1 117, accounting for 2.39%. The highest detection rate was 34.23% in January-March, and the highest positive rate was in 5-year-9 age group, accounting for 34.35%. Conclusion: The surveillance showed that the major epidemic strain of influenza in Fengxian District in Shanghai in 2010 was B type. The epidemic of influenza was characterized by high incidence in winter and spring. The age group of 5 to 9 years old was a high incidence population.
