Bay Area researchers are beginning the first major U.S. study into a mystery disease known for its frightening symptoms - among them, open sores and unidentifiable objects poking out of the skin - that doctors have long suspected is all in patients’ heads. The study into Morgellons will start immediately, as Kaiser Permanente contacts Northern California patients who have reported symptoms of the mystery disease in the past 18 months. The research will be funded by the U.S. Centers for Disease Control and Prevention.
