MELIAN-RIVAS, Andrés; CALCUMIL-HERRERA, Pablo; BOIN-BAKIT, Camila  and  CARRASCO-SOTO, Rolando. Detection of COVID-19 (SARS-CoV-2) by Saliva: A Low-invasive Diagnostic Alternative. Int. J. Odontostomat. [online]. 2020, vol.14, n.3, pp.316-320. ISSN 0718-381X.

The new coronavirus disease, also called COVID 19, is the latest infectious disease of international concern. Originating in Wuhan, China, it spread globally, resulting in the 2019-2020 pandemic and a Public Health Emergency of International Concern (ESPII) as declared by the World Health Organization (WHO). This disease usually presents with fever, cough, sore throat, respiratory distress, fatigue and general discomfort; however, asymptomatic cases have been reported. The diagnosis is made with a combination of clinical, radiological and laboratory molecular tests, where the reverse transcriptase polymerase chain reaction (RT-PCR) test has been the alternative of choice for the analysis of viral genetic material from samples taken of upper respiratory tract. COVID-19 has been reported to be transmitted person-to-person or by indirect fluids drop contact, which is of fundamental importance for clinical dental procedures and where saliva would play a critical role in the transmission of SARS-CoV-2 from human to human. For this reason, non-invasive salivary diagnoses could provide a platform for rapid, early and non-invasive detection of COVID19 infection. The objective of this review is to determine the benefits of saliva as a non-invasive sample for the diagnosis of COVID-19.
