即便新病毒在未来几个月内威力减弱，世界各国的政策制定者们——他们大多数来自北半球——也不应该愚蠢地认为它在很长一段时间内都不会卷土重来。

The world’s policymakers, most of whom live in the northern hemisphere, should not be fooled into thinking the new virus is going away for long, even if it declines over the next few months.

从而我们可以简单地认为H5N1病毒缺乏成为大流行流感的能力，而H5N1要具有更强的传染性，它的致病性就不得不减弱。

That led to hopes that the H5N1 virus simply lacked the ability to be a true pandemic killer and that to become more transmissible, it would necessarily have to become less dangerous.

我们有充分理由猜测，病毒在传播的过程中，其致命毒力逐渐减弱。

There is good reason to suspect the virus will become less lethal as it spreads.
