Good morning.

早上好
We can continue with our subject of Asiatic cholera.

我们继续讨论亚细亚霍乱
And I thought we could perhaps frame that discussion

我想再提一下九十年代的诺贝尔奖获得者
by reminding you that in the 1990s the Nobel Prize winning microbiologist,

微生物学家约瑟夫·莱德勒提出的概念
Joseph Lederer, coined a term, "emerging diseases."

"新型疾病" 以此来明确一下课程的框架
He used it to describe infectious diseases that are previously unknown,

他用这个词来描述以前未知的传染病
at least as sources of human infection, and emerge, as it were,

当其首次感染人类时
for the first time to infect human beings.

或至少是传染源时以此称呼它
These are diseases--

这些疾病包括
in our own day we can think of Ebola or Lyme's disease,

现在所知的埃博拉病毒莱姆关节炎
