How many EVALI cases were reported in the United States observational report?

high confidence  ·  Last reviewed May 22, 2026

The specific number of EVALI cases reported in the United States observational report is tied to data collected as of December 2019. This report details the count of people in the U.S. who were hospitalized for this lung injury at that time. Other reports cover different groups, such as eight cases in California during the early pandemic or 83 cases in Utah.

What the research says

One observational report specifically describes the number of United States persons hospitalized with e-cigarette, or vaping, product use-associated lung injury as of December 2019 3. This data point provides a snapshot of the hospital burden for this condition near the end of 2019.

Separate reports track different populations. For instance, a field report documented eight EVALI cases in California that were reported to the state health department in April 2020 1. Another study focused on Utah residents and described the characteristics of 83 confirmed and probable cases in that state 6.

Additional reports update the characteristics of U.S. patients with vaping-associated lung injury based on data collected as of October 15, 2019 2. These updates help health officials understand how the condition affects different groups of people over time.

What to ask your doctor

  • What is the current number of EVALI cases in my state?
  • How do the symptoms of EVALI compare to other lung infections I might have?
  • What are the signs that I should seek emergency care for vaping-related lung issues?
  • Are there specific vaping products linked to EVALI cases in my area?
