The study was approved by the institute ethics committee (AIIMS/MG/IEC/2020-21/). After obtaining informed written consent, patients with symptoms of SARS-CoV-2 infection attending the sampling area of the hospital were taken for the study. Very sick or unstable patients with all forms of ARDS, sepsis, terminally ill, and patients using mouthwash regularly were excluded.</p><p id="par0030" class="elsevierStylePara elsevierViewall">Saliva was collected by asking the patient to cough saliva from their throat into a sterile container, and 2 mL of viral transport medium was then added. They were asked not to eat, drink, smoke or use oral hygiene products for at least 10 min before the collection process. The nasopharyngeal swab was taken with flocculated swabs inserted into the nostril parallel to the palate just above the floor of the nasal cavity. The swab was inserted till resistance was felt and was left for a few seconds inside the nasal cavity. It was then gently removed by rotating it.</p><p id="par0035" class="elsevierStylePara elsevierViewall">Saliva and Nasopharyngeal swab were collected from patients to detect SARS-CoV-2 by real-time reverse transcriptase RT-PCR. RNA was extracted from clinical samples with a QIAamp viral RNA mini kit (QIAGEN, Hilden, Germany) following the manufacturer’s instructions. A final volume of 50 µl of RNA was eluted and kept at −80 °C till further processing. All specimens were handled with biosafety guidelines per the Indian Council of Medical Research (ICMR)/WHO/Center for Disease Control and Prevention for COVID-19.</p><p id="par0040" class="elsevierStylePara elsevierViewall">After RNA extraction, one-step RT-qPCR (the reverse transcriptase reaction automatically precedes the PCR phase in the same tube) was performed using ICMR approved RT-PCR kitin Quantstudio 5 real-time PCR instrument (Thermo Fisher Scientific Inc.) based on the instruction for use (IFU) provided. Briefly, the master mix (a pre-mixed concentrated solution consisting of buffer, Reverse transcriptase enzyme, nucleotide, forward primer, reverse primer, TaqMan probe, DNA polymerase) was prepared dispensed into PCR tubes, and finally, RNA elutes were added. To check the validity of the test, negative control, positive control, and no template control were also added in each run. The basic cycling conditions were as follows: reverse transcription at 55 °C for 5 min, denaturation at 95 °C for 5 min, and then 45 cycles of amplification at 95 °C for 5 s and at60 °C for 15 s.

This shows the feasibility of using saliva on a larger scale for mass screening in the community. The self-collected non-invasive sample collection technique may make the population more permissible for testing and enhance community surveillance. Another advantage of our study is that we collected both the nasopharyngeal and saliva samples simultaneously from each participant; this will reduce the chance of variation in viral load among the specimens.</p><p id="par0095" class="elsevierStylePara elsevierViewall">There are certain limitations of our study. Firstly our sample size is limited, and the setting is hospital-based.

It is postulated that the use of saliva will reduce the risk of transmission of infection to healthcare workers, which will reduce the healthcare worker burnout seen during the pandemic. In addition, the demand for personal protective equipment and swabs will also reduce, thereby decreasing the cost of testing. The feasibility of using saliva in community settings should be explored further. In addition various aspects like asymptomatic presentation, severity of disease, positive history of contact, paediatric vs. adult, late vs. early course of disease should be evaluated in further studies as they may influence the results.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Conflict of interest</span><p id="par0105" class="elsevierStylePara elsevierViewall">None.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:12 [ 0 => array:3 [ "identificador" => "xres2031171" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Aim" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Method" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Result" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusion" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1737990" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xpalclavsec1737989" "titulo" => "Abbreviations" ] 3 => array:3 [ "identificador" => "xres2031172" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Objetivo" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Método" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultado" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusión" ] ] ] 4 => array:2 [ "identificador" => "xpalclavsec1737988" "titulo" => "Palabras clave" ] 5 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 6 => array:3 [ "identificador" => "sec0010" "titulo" => "Method" "secciones" => array:1 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Statistical analysis" ] ] ] 7 => array:2 [ "identificador" => "sec0020" "titulo" => "Result" ] 8 => array:2 [ "identificador" => "sec0025" "titulo" => "Discussion" ] 9 => array:2 [ "identificador" => "sec0030" "titulo" => "Conclusion" ] 10 => array:2 [ "identificador" => "sec0035" "titulo" => "Conflict of interest" ] 11 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2022-08-06" "fechaAceptado" => "2022-12-06" "PalabrasClave" => array:2 [ "en" => array:2 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1737990" "palabras" => array:4 [ 0 => "Saliva" 1 => "Nasopharyngeal swab" 2 => "COVID 19" 3 => "SARS-CoV 2" ] ] 1 => array:4 [ "clase" => "abr" "titulo" => "Abbreviations" "identificador" => "xpalclavsec1737989" "palabras" => array:7 [ 0 => "COVID-19" 1 => "RTPCR" 2 => "NPS" 3 => "Ct" 4 => "SARS" 5 => "MERS" 6 => "LR" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1737988" "palabras" => array:4 [ 0 => "Saliva" 1 => "Hisopado nasofaríngeo" 2 => "COVID-19" 3 => "SARS-CoV-2" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Aim</span><p id="spar0020" class="elsevierStyleSimplePara elsevierViewall">A simple and reliable method for diagnosing COVID 19 infections is the needed.
