Dozens of US teens hospitalized with lung disease after vaping

US health officials are investigating the cases of dozens of people, mainly teens, who were hospitalized with severe lung injuries in recent weeks after vaping, though the precise cause of their illnesses remains a mystery. Health departments in Illinois, Minnesota and Wisconsin have issued statements describing cases involving patients who exhibited coughs, shortness of breath, dizziness and fatigue, symptoms that led them to hospitals where they had to be intubated. Officials in the three states, which have reported at least 30 confirmed cases and 22 under investigation, said it was too early to say whether the illnesses were connected, but were working with each other and the Centers for Disease and Control and Prevention to investigate further.
