The outbreak of lung illnesses linked to vaping grew by more than 200 cases in a week, now totaling 1,299, the Centers for Disease Control and Prevention reported on Thursday.

Twenty-nine people have died from vaping-related illnesses, health officials said.

The figures mean that 219 new cases and seven new deaths were reported. Cases have occurred in 49 states, the District of Columbia and the United States Virgin Islands.

A 17-year-old boy died in the Bronx last week, the youngest death so far linked to vaping. Utah and Massachusetts officials confirmed their states’ first vaping deaths this week. Indiana health officials announced late Thursday afternoon that two more people had died.
