流行性感冒是由流感病毒引起的急性呼吸道传染病,主要通过空气飞沫传播,传染性强,潜伏期短,传播迅速;全年均可发病,可有季节性爆发或流行。流感病毒分为甲(A)、乙(B)、丙(C)3型,甲型流感病毒变异频繁而引起流感反复流行和大流行,乙型变异少见,丙型相对稳定。2009年起,义乌市疾病预防控制中心被纳入国家流感监测网络实验室,正式启动国家级哨点医院流感监测工作。为了解义乌市流感流行态势,为义乌市流感防治提供科学依据,现将2012年流感监测网络实验室流感病原监测结果分析如下。
Influenza is an acute respiratory disease caused by the influenza virus, mainly spread through the air droplets, infectious, short incubation period, spread rapidly; can be sick throughout the year, there may be a seasonal outbreak or epidemic. Influenza virus is divided into A (A), B (B), and C (C) 3 types. Influenza A viruses frequently cause frequent outbreaks of influenza and pandemic influenza. Type B mutations are rare and type C viruses are relatively stable. Since 2009, Yiwu Municipal Center for Disease Control and Prevention has been included in the National Influenza Surveillance Network Laboratory, which officially started the work of influenza surveillance in national sentinel hospitals. In order to understand the epidemic trend of Yiwu City, provide a scientific basis for the prevention and treatment of influenza in Yiwu City, now the 2012 influenza surveillance network laboratory influenza pathogen monitoring results are as follows.
