Authorities in the United States are reporting a significant rise in the number of cases and deaths linked to the current outbreak of e-cigarette related lung injury.
As of September 24, 805 cases of the lung injury have been reported from 46 states and one US territory, up from 530 cases last week. On the same date, 12 deaths had been confirmed in 10 states.
The Centers for Disease Control and Prevention (CDC) has received complete sex and age data on 373 cases. Of these cases, almost three-quarters (72%) are males and two thirds (67%) are aged 18 to 34 years.
Authorities are continuing their investigating into the cause of the outbreak. The CDC says that while all reported cases have a history of e-cigarette product use or vaping, the investigation has not identified any specific e-cigarette or vaping product or substance that is linked to all cases.
The CDC has issued recommendations for physicians regarding the outbreak. It says clinical improvement of affected patients has been reported with the use of corticosteroids, but advised physicians that the decision to use corticosteroids should be made on a case-by-case basis.
