Interestingly, delusions, such as contagious diseases, can be spread from one susceptible person to another susceptible person. This is how the Internet can serve as a "vector" or transmitter of illness.
Sociologist Robert Batholomew recently suggested the "World Wide Web has become the incubator for mass delusion and it (Morgellons) seems to be a socially transmitted disease over the Internet."
While it's true that there has been an internet explosion of snake-oil treatments trying to cash in on folks who think they have Morgellons, I think it's a little early to conclude that the whole thing is a hoax. Let the CDC do their job, and then report on it. Jeeze.
