The current outbreak of the highly contagious, animal origin SARS-CoV-2 virus causes the disease COVID-19. The disease is globally pandemic and as per World Health Organization (WHO) has spread to 235 countries. There is global lockdown for containment of the virus transmission. ⋯ WHO recommends nasopharyngeal (NP) and oropharyngeal (OP) swab for the quantitative assessment of SARS-CoV-2 RNA level through real-time reverse transcription polymerase chain reaction (rRT-PCR). The virus is shown to be consistently present in saliva and rRTPCR of saliva specimens and have advantages over NP and OP swabs such as self-collection of saliva, avoidance of healthcare workers for specimen collection, cost-effectiveness, etc. This article explores the current literature and suggests saliva as an emerging potential diagnostic specimen for COVID-19 testing.
