目的:了解2009~2010年新型甲型H1N1流感大流行期间,大连市郊区流感病毒的流行情况。方法:对大连市外各区的流感样病人咽拭子标本采用Real-time RT-PCR方法进行流感病毒核酸检测。结果:2009年11月~12月郊区标本均为新型甲型H1N1流感病毒核酸阳性,2010年1月部分地区标本季节性流感病毒核酸阳性,2010年2月后各区标本均季节性流感病毒核酸阳性。结论:2010年1月为新型甲型H1N1流感病毒和季节性流感病毒交替期,之前流行株为新型甲型H1N1流感病毒,之后的流行株为季节性流感病毒。
Objective: To understand the prevalence of influenza virus in the suburbs of Dalian during the new influenza A (H1N1) pandemic from 2009 to 2010. Methods: Real-time RT-PCR was used to detect the influenza virus nucleic acid in throat swab samples of influenza-like patients in all districts outside Dalian. Results: The subtype of the new influenza A (H1N1) virus from November 2009 to December 2009 was positive. In January 2010, the samples of seasonal influenza viruses were positive in some areas of China. After February 2010, all the samples were positive for seasonal influenza virus nucleic acid . Conclusion: In January 2010, the new influenza A (H1N1) virus and the seasonal influenza virus were alternated. The former epidemic strain was the new type A (H1N1) virus and the later was the seasonal influenza virus.
