什么是猪流感？What is Swine Influenza?

猪流感(Swine Influenza, swine flu)是猪的一种呼吸道疾病，它的病原是一种能造成周期性爆发的A型流感病毒。猪流感病毒的致病率很高，但猪的死亡率低。猪流感病毒在全年都有可能传播，但大部分会在深秋和冬季月份爆发，这一点与人流感类似。典型的猪流感病毒(A型H1N1病毒)于1930年第一次从猪身上分离出来。

Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Swine flu viruses cause high levels of illness and low death rates in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans. The classical swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930.
