Oh, my head is fine. I, er, took injury to my torso. [Which isn't a better answer, really. A lot could go wrong when there's so many organs at risk and the infection isn't anything to sneeze at.]

Wilder's request. We had to kill some infected creatures. Luckily, it seems that despite being stripped of our original magic, we kept some particulars. I've found that average people are much more fragile in physiology than wizards. I'm happy to say that my physiology still is intact. [A fancy way of saying that Theseus and Newt can weather stupid decisions easier.]
