CDC today announced the updated number of confirmed and probable lung injury cases and deaths associated with e-cigarette product use, or vaping.

Patients with Lung Injury

    • The increase of 275 cases since last week is a combination of new patients becoming ill in the past two weeks and recent reporting of previously-identified patients.

    • About 78% reported using THC-containing products, with or without nicotine-containing products; 37% reported exclusive use of THC-containing products; and
    • 17% reported exclusive use of nicotine-containing products.
    • These percentages are consistent with previous reports.
  • About 70% of patients are male.
  • Approximately 80% of the patients are under 35 years old; 16% are under 18 years old.
    • The median age of patients is 23 years, ranging from 13 to 75 years old.

    • The median age of patients who have died is 50 years, ranging from 27 to 71 years old.

“The increasing number of lung injury cases we see associated with e-cigarette use, or vaping, is deeply concerning. Unfortunately, this may be the tip of the iceberg when it comes to the escalating health threat this outbreak poses to the American public, particularly youth and young adults. CDC will continue to work with FDA and state health partners to investigate the cause, or causes, of this outbreak and to bring an end to these lung injuries.” – Dr. Robert R. Redfield, MD, Director of the Centers for Disease Control and Prevention.
