Self-collected gargle fluids and nasopharyngeal swabs as a strategy for molecular diagnostics of respiratory viruses

Diagnosis of respiratory viruses traditionally relies on deep oropharynx or nasopharynx swabs collected by healthcare workers (HCW). However, outpatients must make an appointment, and the procedure can cause discomfort in patients. Self-collecting has the potential as a strategy to improve participants’ willingness to participate in diagnostics, surveillance, or studies.
