Hmm, I'm no medical expert, but I think a recurrence of the malaria might have further consequences? Also, if that happens, you can die painfully of liver disease. I'd go for 'flu. Given the state of everything on the Island, 'flu, even for the Kommandant, would always be an option.

(I'm amused at this question. I was having a thought last night (that probably won't lead anywhere) and, aha, giving Richter a minor injury. I think great minds may be thinking alike here. Which is excellent. :loL:)
