Preseptal cellulitis and infraorbital abscess as a complication of a routine COVID-19 swab

This case report describes a significant complication of a routine COVID-19 swab in a previously fit and well young patient who developed preseptal cellulitis and an infraorbital abscess as a consequence of the mentioned nasal swabbing. Other authors have previously reported various complications in connection with the use of nasal swabs, including retained swab fragments, epistaxis and cerebrospinal fluid leakage. To our knowledge, to date, this is the first reported case of an abscess as a consequence of COVID-19 swabbing. There has been a clear growth in the use of nasal swabbing worldwide over the last 9 months and many healthcare workers involved in COVID-19 prevention may not be aware of the potential risks of nasopharyngeal swabbing. The presented case highlights the need for better awareness of the complications of these routine tests and we hope that it will also lead to their safer implementation.
