Nasopharyngeal swab-induced pain for SARS-CoV-2 screening: A randomised controlled trial of conventional and self-swabbing.

Using the thinnest available swabs, procedural pain induced by nasopharyngeal swabbing for SARS-CoV-2 screening is very low for most subjects and should not limit voluntary participation in screening campaigns. Self-swabbing does not lead to more pain or discomfort compared to conventional swabbing, is well-accepted, and could be proposed to optimize screening campaigns, at least in healthcare professionals.
