乙型流感病毒病原学研究现状

乙型流感病毒是一种流行性感冒病毒，特定季节能够在人际间传播流行引起流感及其他并发症；近年来由其造成的疾病负担日趋严重，因此了解和掌握乙型流感病毒病原学特征和变异规律，才能更好的为乙型流感的防控提供科学依据。本文主要从乙型流感病毒的病原学特征、病毒的进化、致病、传播、流行以及对乙型流感病毒的药物、疫苗控制等方面进行综述。

Current status of research advances on etiology of influenza B virus

Influenza B virus is a kind of influenza viruses that can circulate in population and cause influenza and othercomplications in certain seasons.In recent years，the disease burden caused by Influenza B virus has been heavier than before，which attracted a lot of attention.Therefore，a study of the etiological characteristics and revolution patterns of influenza B viruswill provide a better scientific basis for the prevention and control of the influenza B.This article mainly reviewed thepathogenic characteristics，evolution，pathogenicity，spread，prevalence of influenza B virus，and the drugs and vaccinesagainst influenza B virus.
