Category:

Topic:

  • From a meta-analysis of 12 published papers with a total of 9,025 COVID-19 patients, this study identifies smoking as a risk factor for progression of COVID-19. Smokers had significantly higher odds (OR=2.25) of COVID-19 progression than never smokers. 
  • Physicians and public health professionals should collect data on smoking and e-cigarette use as part of clinical management and add smoking cessation to the list of practices to curb the COVID-19 pandemic.
