The paper by Hopkinson et al (1) provides unique and important data on smoking prevalence and COVID-19 symptoms, but their conclusion does not reflect the data well. [...] The study includes over 150,000 people with self-reported COVID-19 symptoms and over two million without such symptoms. It also includes data on over 25,000 people who were tested for SARS-CoV-2 and their test results. Based on our analysis of these more relevant data, we interpret the study differently. Our conclusion would be “these data are consistent with smokers having an increased risk of symptoms such as cough and breathlessness, but a decreased risk of having SARS-CoV-2 infection”.
