Saliva Samples May Be Better Indicators Of SARS-CoV-2 Persistence

  • A recent study explored the persistence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human saliva.
  • Several studies performed on nasal and pharyngeal samples noted a reduction in viral shedding along with a decline in culturable virus within the first week of COVID-19 symptoms.
  • However, only a few studies have assessed the duration for which SARS-CoV-2 is detected in salivary samples in comparison to nasal swabs after the initial week of symptoms.
