Researchers at the Swiss Institute of Bioinformatics estimate that the B.1.1.7 variant may be dominant in Switzerland by March.

A new modeling study published in the journal Science estimates the B.1.1.7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant is 43% to 90% more transmissible than previous coronavirus variants. The variant was initially found in Southeast England last fall.

Study explains how the B.1.1.7 SARS-CoV-2 variant is more transmissible The B.1.1.7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant was initially found in England last fall and has quickly overtaken to become the dominant coronavirus strain in the United Kingdom (UK). The variant’s ability to increase transmission and severe infections has proven to be a challenge for public health officials looking to limit the spread. New research led by Thushan I. de Silva from the University of Sheffield proposes that increases in subgenomic RNA (sgRNA) expression cause increased vi...

Multiple COVID-19 variants of concern have reached Houston, Texas New research by a team at Houston Methodist Hospital in the United States has modeled the aggressive genomic sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) observed in the United Kingdom to document viral community spread in Houston, Texas. Houston has thus become the first American city to document four SARS-CoV-2 variants of concern. Here we report discovery of the UK (B.1.1.7), South Africa (B.1.351), and Brazil (P.1) SARS-CoV-2 variants of concern from patients in the Houston metropolitan region....
