摘要
目的通过浙江省建立的流感监测网络所取得的2006年流感监测结果对流感的流行趋势、病原学变化特点进行分析、总结。方法流行病学监测,哨点医院每周填写流感样病例报表并上报网络;各市县(区)疾控中心(防疫站)的流行病学医师对流感样暴发疫点进行个案调查并上报;病原学监测,监测点医院每周采集流感样病人漱口液5～10份进行流感病毒分离。结果流行病学监测,全年报告暴发疫情40起,罹患率在2.03%～37.95%之间,集中于3～4月份。病原学监测,以B型(Victoria系)为优势流行株,集中于3～4月的暴发疫情,与WHO推荐的2005-2006年度且目前正在使用的流感疫苗株巴拿马系毒株不同。结论呈现冬春季和夏秋季的双峰型分布,上半年以B型为优势流行株,下半年暴发疫情较少且未发现B型流感暴发。
Objective To explore the trend of influenza epidemic and predominant strains of the virus in Zhejiang province in 2006. Methods Epidemiological surveillance was performed. Influenza - like cases were filled in web - based forms weekly by monitoring hospitals. Individual influenza - like cases were surveyed and reported by CDC doctors at district and county levels. Etiological surveillance was also conducted. 5 - 10 mouth - rinsing samples were collected weekly from influenza - like cases in monitoring hospitals for influenza virus separation. Results A total of 40 outbreaks of influenza were reported for the whole year, and the morbidity rates were from 2.03% to 37.95%. Outbreaks occurred mainly in March and April. Etiological surveillance revealed that influenza B （Victoria） was the predominant strain for the year 2006, which was different from Panama vaccine strain （recommended by WHO for 2005 -2006 ）. Conclusion Two peaks of the outbreaks were observed： one in winter - spring, and the other in summer - autumn. Influenza B was the predominant epidemic strain for the first half year, and was not found in the second half year of 2006.
