You are looking at a fundamentally abstract system, so really "blinding sickness" actually probably covers a whole gamut of diseases that have similar symptoms, but are caught in different ways: some might be waterborn, some airborn, some spread by contact etc. - the system does not differentiate, so if you want to make up your own rules, that works!
Well I'm looking to do more of the latter. We've seen paizo take a lot of great strides in this area with a lot of the newer diseases they put out getting actual fluff text to explain them alongside their effects. So to that end I'm looking to see if anyone knows of or has ideas on backgrounds for some of these older diseases that we've had since core and has maybe expanded on them to make them more interesting things in the game.
For example I've always thought that blinding sickness was a disease you picked up from tainted water and I could have sworn that was originally in its write up.
Another one I'd kind of want to see get more attention is Red Ache since it's another one of those early diseases that doesn't really have much story. Like we know it apparently has something to do with red (likely the wound sites getting red and swollen) but what else? Where do you usually get exposed to it, is it an infection like filth fever probably is, what happens to people who can't seem to kick it since it doesn't kill you directly?
