Utah health officials on Monday were reviewing 21 cases of severe, vaping-related illnesses, about a week after the U.S. Centers for Disease Control warned of a cluster of lung disease cases that appear to be linked to e-cigarettes.
The updated number more than doubles the 10 cases the Utah Department of Health had learned of statewide as of last week.
Health officials also are investigating another five unconfirmed cases, department spokeswoman Rebecca Ward said.
Across the country, health officials are looking into an outbreak of severe lung disease that appears to be tied to vaping; the CDC was investigating nearly 200 cases nationwide as of last week, and doctors attributed one death in Illinois to vaping.
