TL;DR: In this paper, the authors show that changes in VOC frequency inferred from genetic data correspond closely to changes inferred by S gene target failures (SGTF) in community-based diagnostic PCR testing.

TL;DR: Investigation of the hypothesis for positive selection of Spike D614G in the United Kingdom using more than 25,000 whole genome SARS-CoV-2 sequences indicates that 614G increases in frequency relative to 614D in a manner consistent with a selective advantage.

TL;DR: The SARS-CoV-2 lineage B.7, now designated Variant of Concern 202012/01 (VOC) by Public Health England, originated in the UK in late Summer to early Autumn 2020 as mentioned in this paper.

TL;DR: In this paper, the authors compared the severity of the delta variant compared with the alpha variant by determining the relative risk of hospital attendance outcomes and found that outbreaks of the Delta variant in unvaccinated populations might lead to a greater burden on health-care services than the alpha variants.

TL;DR: Investigation of the hypothesis for positive selection of Spike 614G at the level of an individual country, the United Kingdom, using more than 25,000 whole genome SARS-CoV-2 sequences collected by COVID-19 Genomics UK Consortium finds that Spike 6 14G clusters are introduced in the UK later on average than 614D clusters and grow to larger size after adjusting for time of introduction.
