Syndromic Surveillance for E-Cigarette, or Vaping, Product Use-Associated Lung Injury

Increases in EVALI were identified in 2019. Using the National Syndromic Surveillance Program, which includes about 70% of U.S. EDs, researchers found a gradual increase in ED visits associated with shortness of breath and e-cigarette use from January 2017 through early June 2019. A sharp increase was identified in June, peaking in September. A subsequent decrease was observed.
