TL;DR: A SARS-CoV-2 variant carrying the Spike protein amino acid change D614G has become the most prevalent form in the global pandemic, and it is found that the G614 variant grows to higher titer as pseudotyped virions.

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: In this article , the authors demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273.529.

TL;DR: Testing HCW is a crucial strategy to optimise staffing levels during this outbreak of SARS, and results from staff testing at Sheffield Teaching Hospitals NHS Foundation Trust are presented.

TL;DR: In this article, the authors assessed RT-PCR swab-positivity in the REAL-time Assessment of Community Transmissibility (RACT) in many countries associated with the Delta variant.
