What is Dr. Shem Musoke’s recollection about his illness?

From the text:

One day I interviewed him, and he said to me that he has almost no
memory of the weeks he was infected inMarburg. "I only remember bits and
pieces," he said. "I remember having major confusion. I remember, before
my surgery, that I walked out of my room with my IV drip hanging out of
me. I don't remember much of the pain. The only pain I can talk about is the
muscle ache and the lower-back ache. And I remember him throwing up on
me."
