Abstract

In this prospective cohort of 30 vaccinated healthcare-workers with mild Omicron variant infection, we evaluated viral culture, rapid antigen test(RAT), and RT-PCR of respiratory samples at days 5,7,10, and 14. Viral culture was positive in 46%(11/24) and 20%(6/30) of samples at days 5 and 7, respectively. RAT and RT-PCR(Ct≤35) showed 100% negative predictive value(NPV), with 32% and 17% of positive predictive values(PPV), respectively, for predicting viral culture positivity. A lower RT-PCR threshold(Ct≤24) improved culture prediction(PPV = 39%; NPV = 100%). Vaccinated persons with mild Omicron infection are potentially transmissible up to day 7. RAT and RT-PCR might be useful tools for shortening the isolation period. [ABSTRACT FROM AUTHOR]

Abstract

Background: SARS-CoV-2 quickly spreads in the worldwide population, imposing social restrictions to control the infection, being the massive testing another essential strategy to break the chain of transmission. Aim: To compare the performance of at-home self-collected samples – saliva and combined nasal-oropharyngeal swabs (NOP) – for SARS-CoV-2 detection in a telemedicine platform for COVID-19 surveillance. Material and methods: We analyzed 201 patients who met the criteria of suspected COVID-19. NOP sampling was combined (nostrils and oropharynx) and saliva collected using a cotton pad device. Detection of SARS-COV-2 was performed by using the Altona RealStar® SARS-CoV-2 RT-PCR Kit 1.0. Results: There was an overall significant agreement (κ coefficient value of 0.58) between saliva and NOP. Considering results in either sample, 70 patients positive for SARS-CoV-2 were identified, with 52/70 being positive in NOP and 55/70 in saliva. This corresponds to sensitivities of 74.2% (95% CI; 63.7% to 83.1%) for NOP and 78.6% (95% CI; 67.6% to 86.6%) for saliva. Conclusion: Our data show the feasibility of using at-home self-collected samples (especially saliva), as an adequate alternative for SARS-CoV-2 detection. This new approach of testing can be useful to develop strategies for COVID-19 surveillance and for guiding public health decisions. [ABSTRACT FROM AUTHOR]

Abstract

The article discusses the role of human saliva as a COVID-19 virus diagnostic tool in paediatric patients, and it mentions saliva analysis in the detection of the SARS-CoV-2 virus in the Brazilian city of Araraquara, São Paulo. Total RNA extraction is assessed, along with symptoms such as sore throat, cough, and fever in children. According to the article, saliva collection is a less invasive strategy for COVID-19 virus surveillance.
