Abstract
Novel coronavirus disease 2019 (COVID-19) outbreak has termed as a controllable pandemic,
and the entire world has come to a standstill trying to mitigate the disease with
health systems. Health care providers, around the globe, are fighting day and night.
Currently, rapid testing is taking place with the help of nasopharyngeal, oropharyngeal
swab, bronchoalveolar lavage, sputum, urine, and blood. All these approaches are invasive
or embarrassing to the infected person. It is observed that salivary glands are hosting
severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) because of angiotensin-converting
enzyme 2 and the detection of high viral loads in the saliva and is playing a crucial
role in virus transmission, especially from individuals showing absolutely no symptoms.
Saliva is proving to be a promising noninvasive sample specimen for the diagnosis
of COVID-19, thus helping to monitor the infection and prevent it from further spreading
by prompt isolation.
