Smoking cessation in the elderly as a sign of susceptibility to symptomatic COVID-19 reinfection in the United States. many respiratory infections.2-4 In the COVID-19 pandemic, questions have been asked about clinical outcomes for smokers, and whether they are equally susceptible to infection, and if nicotine has any biological effect on the SAR-CoV-2 virus (the virus calculation and concluded that this association was indeed statistically significant (OR 2.2 (95% CI 1.3 3.7).
