Recent studies state that UK Variant has a higher death rate

 A highly infectious variant of COVID-19 that has spread around the world since it was first discovered in Britain late last year is between 30% and 100% more deadly than previous dominant variants, researchers said on Wednesday.

In a study that compared death rates among people in Britain infected with the new SARS-CoV-2 variant – known as B.1.1.7 – against those infected with other variants of the COVID-19-causing virus, scientists said the new variant’s mortality rate was “significantly higher”.

It has 23 mutations in its genetic code – a relatively high number – and some of them have made it far more easily spread. Scientists say it is about 40%-70% more transmissible than previous dominant variants that were circulating.

Lawrence Young, a virologist and professor of molecular oncology at Warwick University, said the precise mechanisms behind the higher death rate of the B.1.1.7 variant were still not clear, but “could be related to higher levels of virus replication as well as increased transmissibility”.
