SUMMARY:
Objective: The objective of this review was to evaluate the role of saliva tests for the diagnosis of Covid-19. Methodology: This is a literature review study performed between July and November of 2020. The languages used were Spanish and English. We used multiple search engines such as PubMed, Scopus, Redalyc, Google Scholar, Ebscohost, SciELO, and Springer to obtain scientific articles on the subject. The article also includes short systematic researches, pilot clinical trials, literature reviews, letters to the editor, and information from an electronic document. Results: The results indicate that the diagnosis of Sars-Cov-2 in the saliva is a non-invasive procedure that allows a rapid and early detection of the disease. This method also enables monitoring while reducing the risk of nosocomial transmission. Thus, it is useful in the replacement of nasopharyngeal swabs when they are contraindicated. In addition, salivary specimens are reliable in the molecular analysis due to their self-collection which also minimizes errors during sample transfer. The cost is lower and is not invasive. This is particularly important if epidemiological procedures are performed with limited resources. Conclusions: The paper's main conclusions are based on new evidence that shows saliva as the fluid that offers several benefits for the diagnosis of Covid-19 including the simplicity of the process, the cost, and especially the ability to detect the disease in acute phases.
KEYWORDS: Sars-Cov-2; Covid-19; Saliva tests; Sars-Cov-2 diagnosis; betacoronavirus.
