Abstract

Nasopharyngeal swabs (NPS) are recommended by the World Health Organisation (WHO) as the current standard method to detect SARS-CoV-2 in suspected patients.1WHOLaboratory testing of 2019 novel coronavirus (2019-nCoV) in suspected human cases. 2020; (Accessed 1st December)https://www.who.int/publications-detail/laboratory-testing-for-2019-novel-coronavirus-in-suspected-human-cases-20200117Google Scholar However, collection of an NPS or oropharyngeal swab (OPS) can be technically difficult, uncomfortable for patients, may induce sneezing or coughing, and expose those nearby to aerosolised SARS-CoV-2).2Marty F.M.
