They say that blackwater fever begins with loss of appetite and nausea, which I have.

他们说我得的是黑水热，开始会呕吐和没有食欲。

My dear young woman, I fear that blackwater fever is going to be the least of your worries.

哦年轻人，我想黑水热不会使你困惑了。

Blackwater fever is not that difficult to diagnose, and you would be dead already if you had it.

诊断黑水病是不难的，如果你得的是黑水病，你已经死了。
