Disease and Sickness

Hello, this is my first post, and I would like to congratulate 
everyone involved in this.  I've spent a lot of today going through 
the FAQs and other documentation in this group and in the Harry 
Potter Lexicon, and I am really blown away by the work and effort 
that has obviously gone into all of this.  The only description that 
comes to mind is "communal labor of love".  It is with a little 
trepidation that I post my first question, because it's probably been 
addressed somewhere already, but here goes....

Is there anything in canon or conjecture that mentions sickness and 
disease in the wizarding world?  I've been re-reading the books 
recently and although it's clear that they are subject to all manner 
of injuries, curses, and wounds, I can't remember an instance of 
someone coming down with any run-of-the-mill colds, aches, sniffles, 
or anything like that.  I believe I remember them suffering belly 
aches from stuffing themselves at the feasts, but that's about it.  
It's completely possible I missed a passage though.  It got me 
wondering however, whether wizards have some sort of immunity to 
muggle diseases and illnesses.  It would have a sort of cosmic 
justice to it, as muggles don't have to put up with the myriad 
mystical and fantastic ways wizards and witches have of dying, but 
then i've never read anything to make me believe that magical folks 
are biologically different from muggles.  If anyone has any thoughts, 
i'd love to hear them. Thanks!
