NEW YORK—U.S. health officials on Nov. 8 announced a breakthrough into the cause of a mysterious outbreak of vaping illnesses, reporting they have a “very strong culprit.”
The same chemical compound was found in fluid taken from the lungs of 29 patients across the country, the Centers for Disease Control and Prevention said. The compound—vitamin E acetate—was previously found in liquid from electronic cigarettes and other vaping devices used by many of those who got sick.
