Some 2,561 people were hospitalized last year for lung injuries associated with e-cigarette, or vaping, product use EVALI, according to the CDC. EVALI hospitalizations or deaths were reported by all 50 states, the District of Columbia, and 2 U.S. territories (Puerto Rico, and the U.S. Virgin Islands).

There were 55 confirmed EVALI deaths, in the District of Columbia and 27 states: Alabama, California, Connecticut, Delaware, the District of Columbia, Florida, Georgia, Illinois, Indiana, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, and Virginia.

The CDC said more deaths are under investigation.

Data on emergency department (ED) visits suggest that the current EVALI outbreak began in June 2019. Cases have been declining since a peak in September, although they have not returned to levels before June 2019 and EVALI “remains a concern,” according to the agency.
