@Prince of Seraphs I think I was going with tetanus because if rust was involved, then magic wouldn't work to fix it. Iron and all that.
Even if they're not affected by human sicknesses, I doubt there's no fey diseases at all, even if they're rarely fatal.
MAx: I want to know how they handle disease so well when their tech is clearly rather primitive.
@BlackPantherI'm quite certain there's bacteria that go back and forth -- and certainly with the Moot being held in the human realm there will be some microorganisms crossing over very shortly. Furthermore, I meant more along the lines of a disease that affected primarily humans, not fey, as I imagine some but not all diseases are shared. Though really, it's likely only small percentage are, as is the case with the various species of plants and animals irl.
Regardless of whether it's a disease /from/ the human realm or not, there are going to be diseases in the realm of faerie that affect humans. Just as there are animals that live there. Nor have we established that all flora and fauna is distinct from that of the human realm, so identical or at least practically similar microorganisms doubtless exist in both places as well. Think of it like Madagascar, at the very worst. Used to be very closely connected, now not so much, but they shared a great deal at one time despite evolutionary paths leading down different routes.
Actually, that is a thought. I wonder if fey heading to the mortal realm and mortals being taken to the fey realm need vaccinations to lessen the risk of becoming severely ill....
Max: I could find out. IF SOMEONE WOULD BOTHER USING THE SCIENTIFIC METHOD AND GIVE ME THE RIGHT TOOLS! T.T Well, actually that's not my field -- I was studying pediatrics, not research medicine. Still, I know the basics?
