Authorities in the United States are reporting a continued, albeit slower, increase in the number of cases of e-cigarette- or vaping product use-associated lung injury (EVALI) being reported. 

According to the latest data from the US Centers for Disease Control and Prevention (CDC), as of 22 October, 1,604 reports of EVALI were received from 49 states (all except Alaska), the District of Columbia and one US territory, representing an increase of 125 cases from the previous week. To date, 34 deaths have been reported. 

On Friday, the CDC noted that an epidemic curve of cases suggests that the trajectory may be levelling-off or even declining and said this pattern may or may not be confirmed with additional time. “There may be less intensive investigation of possible cases by the health departments, fewer cases from earlier in the year being reported in to the public health system, or lags in data reporting to the CDC,” said Dr Anne Schuchat, Principle Deputy Director of the CDC. Dr Schuchat said it is also possible supply chains may be impacted by the consumer warnings on products containing tetrahydrocannabinol (THC). 

The CDC added, however, that it is uncertain how the upcoming influenza season will impact on cases.
