A total of 12 people have died and at least 805 others across 46 states have sustained lung damage after using e-cigarettes, the Centers for Disease Control and Prevention said Thursday. The latest figures show that the number of known vape-related illnesses has increased by 275 since last week. It also increases the number of affected states by eight. News of the 52% rise came hours after the Mississippi State Department of Health announced its first confirmed vape-related death. The individual was only identified as under the age of 30. Earlier this week, health officials in Florida and Georgia also announced their first deaths from vaping-related illnesses.

Georgia health officials identified the deceased individual as a 35-year-old man who had a history of heavy nicotine vaping, but no history of vaping THC. The Florida Department of Health has not released details about its fatality and did not immediately respond to a request for comment. Most nationwide cases of vaping-related lung damage have involved individuals with a history of using products containing THC, though there have been cases of people who only used nicotine, according to the CDC. As of this week, there are eight other vaping-associated illnesses in Georgia. “All patients were hospitalized and developed pneumonia with no known infectious cause,” the Georgia Department of Public Health said. All of the individuals are between the ages of 18 and 68 and nearly all are male. Florida has reported 27 known cases of lung damage associated with e-cigarette use this year.
