The Complexity in the Diagnosis and Treatment of Symptoms in Electronic Cigarette Users during the COVID-19 Pandemic

The issue with the overlapping clinical symptoms from an electronic cigarette (e-cigarette) or vaping product use-associated lung injury (EVALI) and coronavirus disease 2019 (COVID-19) sometimes leads to incorrect diagnosis and, consequently, wrong treatment regimen. The purpose of this review is to study the burden of vaping-associated health consequences on the diagnosis and treatment of COVID-19 in young adults and adolescents with a misconception of e-cigarettes as a safer alternative to smoking. The online reference databases, including PubMed, Google Scholar, Web of Science, Medline, and Centers for Disease Control and Prevention (CDC), were used in the literature search, as we analyzed the complexity of timely diagnosis and treatment in the current COVID-19 era with the use of e-cigarettes. This study briefly describes the dysbiosis of the oral microbiome in e-cigarette users that could potentially aggravate the COVID-19 symptoms and lead to the complexity of timely diagnosis and treatment. Additionally, the patient case reports with a history of vaping and symptoms similar to COVID-19 disease are reviewed.
