I'm planning a House fanfic involving a disease engineered for offensive/black-market weapons purposes. Essentially, a woman walks into the clinic with certain symptoms that, at first, would raise no alarms, and seem easily treatable: the doctor sends her home with a diagnosis and a prescription, but it gets worse, and a few days later she's near death.
Obviously, the actual disease would be fictional, something invented for the purposes of the story. What I need is something that fits the apparent symptoms, in two stages:
-the first, non-life-threatening diagnosis
-a second diagnosis, fitting the advanced symptoms
Basically, two diseases of varying severity that fit the same symptoms, and could also plausibly be caused by a virus or other disease specifically engineered to kill.
What these symptoms actually are is flexible; I'm thinking rash, maybe localized pain at first, but really anything goes. I've tried looking at medical databases, but the problem is I don't even know where to
start. I was thinking that it could be something that appears genetic/inherited at first, but again, I'm not wedded to the idea.
I apologize for the excessive vagueness of this post, but I really don't have the first clue what I'm talking about, or how to go about searching for it. Any suggestions on where to look, or what to look for, would be greatly appreciated. Thank you kindly.
