Summary: This article presents an automated, high-throughput screening platform for sensitive detection of SARS-CoV-2 RNA in infectious carriers using saliva samples. The Sentinel testing instrument, with a reporting time of 25 minutes and a throughput of up to 3840 results per hour, has been independently validated and found to have a sensitivity of 98.7%, specificity of 97.6%, and accuracy of 98% when compared to a RT-PCR comparator assay.

Summary: This study systematically reviewed the duration of protection provided by COVID-19 vaccines against various clinical outcomes. The findings indicate that the effectiveness or efficacy of the vaccines decreased from 1 to 6 months after full vaccination, but remained high against severe disease. Evaluating the effectiveness or efficacy of vaccines beyond 6 months is crucial for updating vaccine policies.

Summary: The COVID-19 pandemic has led to a public health crisis due to the spread of SARS-CoV-2 through presymptomatic, symptomatic, and asymptomatic individuals. Effective population screening for the virus is essential for reopening societies and controlling its spread, with testing frequency and reporting speed playing crucial roles in its success. Test sensitivity is only marginally important compared to these factors.

Summary: The study used Bayesian statistical model to analyze PCR testing data of UK healthcare workers, finding that the detection probability peaked at 77% 4 days after infection but decreased to 50% by 10 days. Testing every other day was estimated to detect 57% of symptomatic cases before onset and 94% of asymptomatic cases within 7 days if results are returned promptly.

Summary: A pilot program in Omaha, Nebraska, tested staff and students in 3 urban public schools for SARS-CoV-2 over a 5-week period, detecting a higher infection rate compared to county-level data. Different experiences were observed among schools, and virus sequencing and geographical analyses indicated a dynamic relationship between school-based and community-derived transmission risks. These findings offer insights into the effectiveness and community value of test-based SARS-CoV-2 screening and surveillance strategies in kindergarten through 12th grade educational settings.

Summary: BNT162b2 vaccine remains highly effective and safe over the course of 6 months post-vaccination, with efficacy rates ranging from 86% to 100% across different demographics and risk factors for Covid-19. The vaccine also shows a high efficacy against severe disease, with particularly promising results observed in South Africa against the B.1.351 variant.

Summary: The B.1.617.2 (Delta) variant of SARS-CoV-2 has lower sensitivity to antibodies and higher replication efficiency compared to other lineages, which may contribute to its dominance and reduced vaccine effectiveness, highlighting the need for continued infection control measures post-vaccination.
