What Do PCs Do When They Get Sick?

This thought often occurs to me when some virus or flu knocks me for a loop. PCs frequent cold, dank dungeons, sleep on floors, eat trail rations, horrid sanitary conditions and drink from water sources that may be less then fresh.

And yet I've yet to see a cleric spell that addresses illness. Wounds, diseases, blindness, lost limbs, even lost minds and the raising of the dead - yes. A cure for the common shits, flu, cold, rash, fever, etc - nada.

If I had to adventure the way I currently feel, the party would be dragging dead weight.

I wouldn't be in this soft, warm bed milking it for all it's worth, either ;)
