influenza pandemic

基本解释

As announced earlier this month, the world is at the start of the 2009 influenza pandemic.
正如我们在本月初宣布的那样，世界已进入2009年流感大流行初期。
But we do know, from a recent World Bank estimate, that the global economic costs of the next influenza pandemic could reach US$ 3 trillion.
但是，我们从最近世界银行的估算中知道，下一次流感大流行在全球造成的经济费用可达3万亿美元。
While no one can predict the timing or severity of the next influenza pandemic, governments around the world are taking the threat seriously.
虽然没人能够预言下一次流感大流行的时间或严重性，但世界各国政府都正在严肃对待这一威胁。

The World Health Organization will not declare an influenza pandemic unless a virus becomes widespread in at least two areas of the world.
"For me,the best health news of the previous decade is the fact that the long overdue influenza pandemic has been so moderate in its impact .
This is welcome news for U.S.health officials, who initially had to consider the possibility that the new flu strain's impact could mirror the devastation of the 1918 influenza pandemic that led to tens of millions of deaths worldwide.

Which is a small piece of good news for those charged with contemplating how to deal with an influenza pandemic.
