CDC, the Food and Drug Administration, state and local health departments, and other public health and clinical stakeholders are investigating a national outbreak of electronic-cigarette (e-cigarette), or vaping, product use-associated lung injury (EVALI).

As of October 22, 2019, 1,604 confirmed and probable lung injury cases associated with use of e-cigarette, or vaping, products were reported by 49 states (all except Alaska), the District of Columbia, and the U.S. Virgin Islands. Thirty-four deaths have been confirmed in 24 states: Alabama, California (3), Connecticut, Delaware, Florida, Georgia (2), Illinois (2), Indiana (3), Kansas (2), Massachusetts, Michigan, Minnesota (3), Mississippi, Missouri, Montana, Nebraska, New Jersey, New York, Oregon (2), Pennsylvania, Tennessee, Texas, Utah, and Virginia. The median age of patients who have died is 49 years, ranging from 17 to 75 years.

Most EVALI patients report using THC-containing products before symptom onset. CDC recommends that persons should not use e-cigarette, or vaping, products containing THC. Because the specific compound or ingredient causing EVALI is not known, persons should consider refraining from use of all e-cigarette, or vaping, products.

Detailed information can be found in the CDC MMWR report that was released today. (
