I snagged this from OSU medical site. OSU (Oklahoma State University) is one of the major medical organizations that have been entrusted in studying Morgellons Disease and Morgellons Fibers. If an answer to this mysterious disease comes from anyone, it will more than likely come from this source.
I will keep searching for more answers on this disease, but I just wanted to share this bit of information with you guys. Morgellons is real, according to this paper. In 2007, OSU had just begun its research into the fibers, they may have more info by now. The medical community is very hushed on the matter, as there are some sceintists that have come out and said that Morgellons is caused by manmade nanorobotic fibers.
This article in OSU's journal of Medicine spends a lot of time scolding Morgellons debunkers and goes on to say that the medical community is taking Morgellons very seriously.
It speaks about the mysterious fibers but does not give any clue to what they might be.
