Saliva is a valuable tool for early detection, better treatment, and a better prognosis. Early detection of illnesses is sometimes challenging, and it necessitates additional clinical and laboratory tests, which can delay treatment and have a significant impact on prognosis. A large range of chemicals may be found in saliva, providing useful information for clinical diagnostic purposes.The coronavirus disease pandemic (Covid-19) is the world's largest challenge and global health disaster since World War II. Controlling the epidemic in the community and in hospitals requires a quick and precise diagnosis of Covid-19. For Covid-19 diagnostic testing, nasopharyngeal and oropharyngeal swabs are the suggested specimen types.The collection of these specimens necessitates intimate contact between healthcare staff and patients, which increases the risk of viral transmission. As a result, nasopharyngeal or oropharyngeal swabs are not recommended for sequential viral load monitoring. Saliva specimens are simply collected by having the patient spit into a sterile container. Saliva collection is non-invasive and significantly reduces healthcare personnel' exposure to Covid-19. To develop quick chair side assays for the detection of Covid-19, more study is needed to investigate the potential diagnostic of Covid-19 in saliva.
