Koch's health concerns may sound more like science-fiction than science, but there are growing numbers of people in the United States who claim to have bugs crawling under their skin and wiry multi-colored fibers sprouting from their sores.
They call the condition Morgellons Disease, and it's been blamed on everything from nanotechnology to nematodes. So far, no one has been able to explain its cause or even how to treat it.
Morgellons, also referred to as unexplained dermopathy or fiber disease, is a collection of symptoms that primarily involve the skin. People who have been affected report the sensation of bugs crawling, stinging or burrowing under the skin. Fibers -- single or multi-colored stiff threads -- or black granules are also reportedly found on or beneath the skin [source: CDC]. An array of other symptoms -- such as forgetfulness, aching joints or chronic fatigue -- also go hand-in-hand with Morgellons. What's more, there are those who believe the disease isn't a physical malady at all. Could the physical signs of Morgellons really be caused by mental illness?
Up first, we'll take a look at how Morgellons came to be in the spotlight.
