Abstract
BACKGROUND COVID 19 has been labelled as a global pandemic by the World Health Organization (WHO). The sudden rise in death toll and devastation associated with it has put the entire infrastructure, economy and health sector to test. The only way for the prevention and control of this infectious disease is rapid and accurate screening of masses. Public Health Authorities mainly use antibody testing in hot spots using a mix of RT-PCR and antibody testing nasopharyngeal and orpharyngeal swabs. Considering the potential risk factors, constraints of time, cost and manpower, mass screening for COVID is not possible through nasopharyngeal and oropharyngeal swabs alone. Hence, to search an alternate method to diagnose for the initial screening of patients is the need of the hour globally. Saliva can also be used as one of the diagnostic modalities for coronavirus, helping in the rapid testing of individuals at home or at hospital. The article intends to explain the evidence regarding the reliability of saliva as a diagnostic specimen in COVID-19 patients and demonstrates the association and potential of detecting novel coronavirus in saliva of patients and how its implication in future can aid in diagnosis as a non - invasive diagnostic modality. KEY WORDS COVID 19, Throat Swab, Nasopharyngeal Swab, Saliva, Diagnostic Fluid
