"Really, it's just to answer a public demand," Rutz says of the CDC inquiry. "We've been hearing enough from folks for a number of years. We haven't been able to give them an appropriate answer, and they haven't been able to get it elsewhere. So we thought it was time for us to shed some light on it."
The fact that a small number of influential lawmakers -- U.S. Sen. Dianne Feinstein (D-Calif.) among them -- have written asking the CDC what experts there know about the purported disease has helped fuel a new urgency to get to the bottom of Morgellons. "Certainly you don't ignore those," Rutz says.
Missing from Rutz's explanation, however, is how unusual that makes this probe. Unlike most such investigations, the CDC's inquiry is a response, overwhelmingly, to patients who believe they have the disease, not to a groundswell of confusion or professional concern from the medical community that sees these patients.
Public outcry has played a key role in prompting many past CDC investigations, but nearly all have had the added impetus of a call for help from the medical community.
In the case of Morgellons, that outcry has been muted, at best.
Diagnosis and treatment
"The vast majority" of physicians who see these patients, says Torrance dermatologist Mark Horowitz, are in little doubt of the correct diagnosis -- delusional parasitosis -- and its proper treatment -- antipsychotic medications such as Orap or its generic form pimozide.
It is not, Horowitz is quick to note, because antipsychotic medication has any power against parasites, but because these patients -- whom Horowitz and his dermatologist father have seen in the hundreds over 30 years -- "have a psychological disorder that's very limited in its spectrum."
In many cases, Horowitz says, they are functioning well in jobs and society, and bear no signs of mental illness. "They act normally," Horowitz says. "But something is wrong."
The recent upsurge in symptoms can be traced directly to the Internet, following the naming of the disease by Mary Leitao, a Pennsylvania mother struggling to explain her young son's mysterious rash, which she first noticed in 2001. She plucked the term Morgellons from an obscure 17th century French medical text describing "strange hairs" sprouting from children's backs, accompanied by coughing and convulsions.
Although such symptoms go back hundreds of years, by 2004, Leitao's descriptions of her son's condition -- and the name she had adopted for it -- were circulating widely online, picking up speculation and conspiracy theories along the way.
Morgellons also picked up patients, raising the question of whether the websites had become a meeting place for sufferers or an incubator for a nightmare with no basis in reality.
Medical history is replete with colorful accounts of the phenomenon known as "mass delusion," which cause outbreaks of physical symptoms that are quickly attributed to infection, poisoning or, of course, metaphysical causes. But those medical curiosities have generally been limited by the means of common communication.
The World Wide Web, however, has made that communication global, with the result that real or imagined, anyone with any of the Morgellons symptoms and an Internet connection can develop a fierce conviction that he or she is infected.
Patients for decades have been coming to physicians' offices with complaints of infestation by bugs, says Dr. Noah Craft, assistant professor of dermatology at Harbor-UCLA Medical Center. But now, when they come in, many are armed with a fat printout of information, a community of fellow sufferers with whom they've exchanged information and a name to put to their bizarre symptoms.
"It seems to be a socially transmitted disease over the Internet, and that's the fascinating phenomenon here," says Robert E. Bartholomew, a sociologist with the Australian government who has studied and written extensively on mass delusions. In his father's early practice, the younger Horowitz says, doctors recognizing the signs of delusional parasitosis would simply write a prescription for an antipsychotic medication. Patients -- unaware that their mental health had been called into question -- would willingly fill the prescription, take the medication and get better, Horowitz says. They still will, he adds, in those rare cases where the patient will accept a diagnosis of mental illness and take the pills.
For the CDC to launch an inquiry into the reported Morgellons symptoms, Horowitz says, is doing patients a disservice. In addition to wasting time and resources, "What CDC is doing is hurting these patients by reinforcing their delusions," Horowitz says. "That's the worst thing you can do for these patients."
Some physicians are not as critical. Craft of Harbor-UCLA believes that the CDC must investigate Morgellons, if only to help quell the groundswell of believers.
Sufferers such as Donna Grace may be skeptical about the CDC's motives, but they have few other places to turn in their bid to vanquish their horrific symptoms.
Last July, Donna Grace said she felt a "mass rumbling" beneath her scalp, and three weeks later, "I felt a hatching of hundreds of thousands of tiny bugs coming down ... crawling throughout my head, down my back.
"It didn't feel like worms as much as like little feet on a mission, finding homes throughout my body. I felt like I was going crazy, and I knew I wasn't."
Without her faith, her family and the care she receives from Savely, says Donna Grace, life would be impossible.
