This is interesting. a report titled, Delusions of Skin Infestatine May Not Be So Rare states that 27 out of every 100,000 (.03%) of the population suffers from delusions of skin infestations. "Mayo Clinic dermatologist Mark Davis. Sufferers have an unshaking belief that pathogens or inanimate objects pollute their skin despite no medical evidence. Davis and colleagues report online April 4 in JAMA Dermatology that the disorder is not as rare as previously assumed." 

Too bad they have no idea what they are talking about. They calculated this number based on the white population and have no idea how prevalent delusions might be among other ethnic groups. 

Another reference, Lyme Disease in the U.S.-Statistics and Facts states that 8.1 out of 100,000 (.008%) have Lyme disease

Wow, they estimate that 3.7 times more people have delusions of skin infestations than have Lyme disease. That's a lot of delusional people, or is that a of people suffering with with Morgellons Disease, mites, and Collembola? Both you and I know the answer to that question.

Too bad we are at loss as to  how to educate the CDC.
