All outcomes related to screening, testing, admission, ventilation, recovery, and death need to be evaluated relative to smoking status and adjusted for comorbid conditions, such as ischaemic heart disease and COPD. To date, there is no strong evidence (i.e., evidence based on causal research) that smokers are protected against SARS-CoV-2 infection. The site is secure.
