Morgellons was named in 2001 by an American called Mary Leitao, whose son complained of sores around his mouth and the sensation of "bugs". Examining him with a toy microscope, Leitao found him to be covered in unexplained red, blue, black and white fibres. Since then, workers at her Morgellons Research Foundation say they have been contacted by more than 12,000 affected families. Campaign group the Charles E Holman Foundation states there are sufferers in "every continent except Antarctica". Thousands have written to Congress demanding action. In response, more than 40 senators, including Hillary Clinton, John McCain and a*pre-presidential Barack Obama, pressured the Centres For Disease Control And Prevention (CDC) to investigate; in 2006, it formed a special taskforce, setting aside $1m to study the condition. Sufferers include folk singer Joni Mitchell, who has complained of "this weird incurable disease that seems like it's from outer space... Fibres in a variety of colours protrude out of my skin: they cannot be forensically identified as animal, vegetable or mineral. Morgellons is a*slow, unpredictable killer – a*terrorist disease. It will blow up one of your organs, leaving you in bed for a year."
So it's new, frightening and profoundly odd. But if you were to seek the view of the medical establishment, you'd find the strangest fact about this disease: morgellons doesn't exist.
