Oct 24 (Reuters) - U.S. health officials on Thursday has reported 34 deaths and 1,604 confirmed and probable cases so far from a mysterious respiratory illness tied to vaping.
Last week, the Centers for Disease Control and Prevention reported 1,479 cases and 33 deaths from the illness and announced plans to start testing aerosols from vaping products as part of its investigation.
Investigators have not linked the cases to any specific product or compound, but have pointed to vaping oils containing THC, the psychoactive ingredient in marijuana, as being especially risky.
The agency has said there may be multiple reasons behind the outbreak and that the cause of the illness may not be the same across the country. (Reporting by Manas Mishra and Saumya Sibi Joseph in Bengaluru; Editing by Shailesh Kuber)
