Variants of SARS-CoV-2
This variant was first detected in October 2020 during the COVID-19 pandemic in the United Kingdom from a sample taken the month before in Kent. Lineage B.1.1.7,  It's correlated with a big increase in COVID-19 infection in United Kingdom, partly because of the N501Y mutation. There is some evidence that this variant has  40%–80% increased transmissibility and an increase in deadliness.
