摘要
目的:了解海盐县流感病毒优势株的亚型变化和流感的流行趋势,为制定流感的防控策略提供科学依据。方法:采用real time RT-PCR法进行核酸检测和型别鉴定。结果:共采集流感样病例咽拭子和漱口液168份,检出流感病毒核酸阳性14份,其中,新甲型H1N1流感5份,B型流感9份。2011年1月-2011年3月是海盐县流感流行的高峰期,新甲型H1N1、B型流感病毒交替出现。结论:2011年流感阳性率8.33%。1月-3月新甲型H1N1流感和B型流感病毒为主要毒株,9月份后以乙型流感为优势毒株。新甲型H1N1流感流行速度快,活动力强,25~岁年龄组人群是此流行期的高危人群。
Objective:To t.nderstand the influenza virus strains subtype variations and influenza epidemic tenden- cy, and provide scientific basis for the development of influenza prevention and control strategies. Methods: The re- al lime RT - PCR method was used for detection of nucleic acids and type identification. Results: One hundred and sixty -eight throat swabs and gargling liquid samples were collected for influenza virus detection, fourteen cases were found influenza virus nucleic acid positive, including 5 new A( HI N1 ) cases and 9 influenza B cases. The pe- riod from January, to March in 2011 was the influenza epidemic peak in Haiyan county, with the alternation of new A ( H1NI ) and influenza B. Conclusion: In 2011, the influenza positive rate was 8.33% , new A( HI NI ) and inIlu- enza B virus were predominant from January to March, but influenza B virus went to the top 'after September. The people above 25 years old were the high - risk population in the epidemic period.
