U.S. health officials said there may be more than one cause to the outbreak of the mysterious lung illness linked to e-cigarette use, and said they do not see a meaningful drop in new cases.
A U.S. House panel sent letters to four e-cigarette companies asking them to stop all print, broadcast and digital advertising of their products in the United States.
The U.S. Centers for Disease Control and Prevention identified 193 potential cases of severe lung illness tied to vaping in 22 states as of Aug. 22, including one adult in Illinois who died after being hospitalized.
