As of Nov. 20, these deaths have been confirmed in 25 states and the District of Columbia, the Centers for Disease Control and Prevention (CDC) said.
Last week, the agency reported 2,172 cases and 42 deaths from the illness.
Earlier this month, U.S. officials reported the discovery of vitamin E acetate — believed to be used as a cutting agent in illicit vaping products containing marijuana components — in all lung samples from 29 patients who were tested.
CDC has called vitamin E acetate a “chemical of concern” and recommended that the substance not be added to e-cigarettes, or vaping products, while the investigation is ongoing.
