以前有过猪流感爆发吗?

【中文原文】

如果你曾经听到过猪流感,很可能是你回忆起了或者读到过1976年那次在新泽西Fort Dix的猪流感在入伍新兵里的爆发.那一次持续了一个月然后消失了.来得突然,去得也很神秘. 当时有240例感染;死亡一例. 在Fort Dix传播的是H1N1型猪流感毒株,与导致灾难性瘟疫的1918-1919年流感相同,那场灾难夺走了上千万人的生命.(1976年)出于一种新H1N1病株大流行可能随着冬季卷土重来的担心, 导致一次匆忙上马的项目,以发明一种猪流感疫苗并对所有美国人接种. 那次疫苗项目后来问题百出-- 其中包括公众恐慌导致了过多的危险的过激反应 ,这还算小麻烦.在4000多万美国人接种后,这个徒劳的努力被放弃了.目前证实尚无猪流感大流行事件.

What Have There Been Previous Swine Flu Outbreaks?

　　　If swine flu sounds familiar to you, it's probably because you remember or have read about the 1976 swine flu outbreak at Fort Dix, N.J., among military recruits. It lasted about a month and then went away as mysteriously as it appeared. As many as 240 people were infected; one died.

　　　The swine flu that spread at Fort Dix was the H1N1 strain. That's the same flu strain that caused the disastrous flu pandemic of 1918-1919, resulting in tens of millions of deaths.

　　　Concern that a new H1N1 pandemic might return with winter led to a crash program to create a vaccine and vaccinate all Americans against swine flu. That vaccine program ran into all kinds of problems -- not the least of which was public perception that the vaccine caused excessive rates of dangerous reactions. After more than 40 million people were vaccinated, the effort was abandoned.

　　　As it turned out, there was no swine flu epidemic.
