Seasonal flu kills 291,000 to 646,000 people worldwide each year, according to a new estimate that's higher than the previous one of 250,000 to 500,000 deaths a year. The new figures from the U.S. Centers for Disease Control and Prevention and other groups were published Dec. 13 in The Lancet medical journal.
还是预防那些不致命的？
比如有的流感就是高烧啊，需要 10天才能好那样的，也不会致命。那比如猪流感，就是比这个还要严重对吧？普通流感即使得了，也没有得死了的感觉吧？很难受就是了。

总不可能全是swine flu, etc 吧。。
真的有同感。普通流感每年都死人，怎么定义流感是否致命这个事呢？
