A 12th American has reportedly died from a vaping-related illness, according to a report.

The news of the latest death in Mississippi comes after the 10th and 11th victims in a national spate of recent e-smoking fatalities were revealed in Georgia and Florida earlier Thursday, according to WLBT.

“There is still so much we don’t know. It’s uncharted territory,” Mississippi State Health Officer Dr. Thomas Dobbs told the local station.

The victim was only identified as a person under the age of 30. Dobbs said Mississippi health officials have also identified four serious lung injury cases linked to vaping — all patients between 18 and 34 years old.

Of the 12 recent vaping deaths, two were reported in California, along with two in Kansas. One each was reported in Florida, Georgia, Illinois, Indiana, Minnesota, Mississippi, Missouri and Oregon, officials said.

In total, at least 805 more people have also reported suffering from vaping-related breathing illnesses — up more than 52 percent from last week, according to The Centers for Disease Control and Prevention.

On Tuesday, Florida’s Department of Health said at least one death this year was the result of a “lung injury associated with e-cigarette use, or vaping.”

The Georgia Department of Public Health announced it had identified the state’s first death from a “vaping-associated illness” the next day.

Over the summer, health officials in several states began noticing reports of people developing severe breathing illnesses, with their lungs apparently reacting to a caustic substance. The only common factor was that the patients had all recently vaped.

As a national investigation began, the number of reported vaping-related illnesses soared.

Most patients have said they vaped products containing THC, the ingredient that produces a high in marijuana.
