The Centers for Disease Control and Prevention (CDC) recently announced that it is collaborating with the US Food and Drug Administration (FDA), state and local health departments, and other clinical and public health partners to investigate a recent, multi-state outbreak of severe pulmonary disease that appears to be associated with e-cigarette use. In 33 states and 1 US territory, 450 cases of lung illness and 6 deaths associated with e-cigarette use have been reported as of early September.
The investigation is in response to multi-state reports of patients being admitted to the hospital with respiratory and gastrointestinal symptoms, such as cough, shortness of breath, or chest pain, nausea, vomiting, or diarrhea. A few other non-specific symptoms were also reported, including fatigue, fever, or weight loss. The exact cause of the reported symptoms is still unknown, however the patients in all cases have a history of using e-cigarette products (e.g., devices, liquids, refill pods, and cartridges).
