Use emergency department visit with e-cigarette, or vapping, product use in the chirf complaint*, by 10-year age group–National Syndromic Surveillance Program, January 1, 2017–December 7, 2009 *Attempts to exclude injuries unrelated elecrtonic-cigaratte (e-cigaratte), or vaping, product use-associated lung ingury (EVALI), such as device explosions and accidental ingestion of e-liquid, but does not exclude potentially related syndromes such as acute intoxication from tetrahydrocannabinol (THC) or nicotin piosoning.

Comparison of weekly counts of US emergency department visits in the National Syndromic Surveillance Program with an e-cigarette, or vaping, product use in the chief complaint, US emergency department visits with EVALI-related diagnosis codes*, Online search interest as measured by Google Trends interest score for terms for e-cigarette, or vaping, from US searches admission date for confirmed or probable cases of EVALI reported to CDC, and April 1, 2019–December 7, 2019. * CDC recommended codes for EVALI, including J68.0 (Bronchitis and pneumonitis due to chemicals, gases, fumes and vapors), J69.1 (Pneumonitis due to inhalation of oils and essences; includes lipoid pneumonia), J80 (Acute respiratory distress syndrome), J82 (Pulmonary eosinophilia, not elsewhere classified), J84.114 (Acute interstitial pneumonitis), J84.89 (Other specified interstitial pulmonary disease), J68.9 (Unspecified respiratory condition due to chemicals, gases, fumes, and vapors). Abbreviations: CDC, EVALI. Source for Google Trends: trends.google.com. A value of 100 for the Google interest score represents peak popularity for the search terms. A value of 50 means the term is half as popular. Search terms were: “vaping”, “vap”, “e-cig”, “e-cigarette”, “ecig”, and “electronic cigarette.”

Within records returned by the search for electronic cigarette, or vaping, product use in the chief complaint, trend in the adjacent word pair (bigram) “shortness breath,” January 1, 2017–December 7, 2019. The trend is represented as the monthly count of the word pair “shortness breath” divided by the total number of all adjacent word pairs (bigrams) in records returned by the search that month
