The deadly effects of these viruses aren't caused by the pathogens directly, but rather, by their host's uncontrolled immune response.

这些病毒的致命影响不是由病原体直接引起的，而是由宿主不受控制的免疫反应引起的。

So I think young virologists today just have this amazing collection of tools and capabilities to understand what's going on in virus biology and the host response at a level that was just never before possible.

所以我认为今天的年轻病毒学家拥有这些惊人的工具和能力，可以在前所未有的水平上了解病毒生物学和宿主反应中正在发生什么。
