Emergence and rapid spread of a new SARS-CoV-2 lineage with multiple spike mutations in South Africa
“Here, we describe a new SARS-CoV-2 lineage (501Y.V2) characterised by eight lineage-defining mutations in the spike protein, including three at important residues in the receptor-binding domain (K417N, E484K and N501Y) that may have functional significance. More...
Mutations arising in SARS-CoV-2 spike on sustained human-to-human transmission and human-to-animal passage
“Spike mutations have also occurred during interspecies transfers of SARS-CoV-2 from humans to animals, both during establishment of experimental models of COVID-19 and as an unintended consequence of human interactions with domestic, curated and commercial animals.” More...
SAGE got it wrong – schools have incubated the deadly new UK SARS-CoV-2 variant B117 after being told to stay open

S-variant SARS-CoV-2 associated with significantly higher viral loads
“This analysis suggests that patients whose samples exhibit the S-dropout profile in the TaqPath test are more likely to have high viral loads at the time of sampling. More...
The new SARS-CoV-2 variant is growing rapidly, is more transmissible, and affecting a greater proportion of under 20s
Greater transmission : The new variant has a transmission advantage of 0.4 to 0.7 in reproduction number compared to the previously observed strain. More...
