Smoking is associated with an increased risk of COVID-19 symptoms and smokers are more likely to attend hospital than non-smokers, a study has found.
The study published today in Thorax, by researchers from King’s College London, investigates the association between smoking and the severity of the COVID-19.
Researchers analyzed data from the ZOE COVID Symptom Study App. Of the participants of the app, 11% were smokers. This is a lower proportion than the overall UK population of 14.7%, however, it reflects the demographics of the self-selected sample of the ZOE COVID Symptom Study.
