They started flooding hospitals with numbness in their hands and feet, high fever, uncontrollable flailing, and loss of sight and hearing.

他们开始涌入医院，手脚麻木、高烧、无法控制的胡乱摆动身体、视力和听力丧失。

But those who have never suffered loss of sight or hearing damage seldom make the fullest use of these blessed faculties.

但是那些听力或视力从未遭受损失的人却很少充分利用这些幸运的能力。

Because of my loss of sight, I got Egan, my good working dog.

由于失明， 我得到了 Egan，我的好工作犬。
