ROSEVILLE CA USA -- Verna Gallagher, who claims to be suffering from a rare infliction called, Morgellons, points to a sore on her skin that she believes the bugs of the condition emerged from, at her Roseville, Calif., home, Tuesday, Aug. 1, 2006. Like others with the condition, Gallagher, 48, said she has a crawling sensation on her skin, that is caused by bugs that emerge from the skin but do not act like they are alive. The Center for Disease Control has been receiving calls from self-diagnosed Morgellons patients, and has been urged to investigate by, among others, U.S. Sen. Dianne Feinstein of California. But so far there is no evidence of an infectious agent, and health officials say there is not yet enough evidence to call it a disease, he added.
