That's a smaller number of illnesses than the agency had previously stated because it has updated the way it reports cases of lung disease associated with e-cigarette use. It's now reporting confirmed and probable cases, rather than possible cases or cases under investigation.
Last week, the CDC had reported that there are more than 450 possible cases of vaping-related lung disease across 33 states and the US Virgin Islands.
There are hundreds more cases under investigation around the country, according to a CNN analysis of numbers reported by state health departments this week.
The states and territory with confirmed cases are Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Iowa, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, North Carolina, North Dakota, Nebraska, New Jersey, New Mexico, Nevada, New York, Ohio, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, Wisconsin, West Virginia and the US Virgin Islands.
"If you are an adult who used e-cigarettes containing nicotine to quit cigarette smoking, do not return to smoking cigarettes," the CDC recommends. "If you have recently used an e-cigarette or vaping product and you have symptoms like those reported in this outbreak see a healthcare provider."
"We will not stand idly by as these products become an on-ramp to combustible cigarettes or nicotine addiction for a generation of youth."
"The FDA plans to share more on the specific details of the plan and its implementation soon," according to the announcement.
Leading e-cigarette maker Juul has maintained that its products are intended to convert adult smokers to what it described in the past as a less-harmful alternative. In other communications, the company has said it cannot make claims its products are safer, in line with FDA regulations.
"We strongly agree with the need for aggressive category-wide action on flavored products. We will fully comply with the final FDA policy when effective," Ted Kwong, a spokesperson for Juul Labs, said after the Trump administration announcement.
"In fact, a recent NACCHO survey of rural local health departments notes that 93% of respondents see e-cigarettes as a public health threat in their community. However, our research also notes that there are real barriers to ensuring that cessation and prevention activities are available in all communities," she said. "We urge the administration to work swiftly to adopt this and other measures to address the youth vaping crisis and to support local communities in addressing tobacco use across the board."
