Federal health officials said 530 people have fallen ill from the mysterious vaping-related lung ailment that has raised alarms across the U.S., up from 380 confirmed and probable cases that the government reported last week.









Seven people have died from the illness, the Centers for Disease Control and Prevention said at a briefing Thursday. Officials said they still hadn’t determined a cause of the ailment, and that there didn’t appear to be one product or substance involved in all instances. Cases have been identified in 38 states.
