The highly infectious variant of the novel coronavirus which swept across the UK last year before spreading worldwide could be 30 to 100 percent deadlier than previous versions of the virus, according to a new study. The research, published in the British Medical Journal on Wednesday, noted that this variant, B.1.1.7, is linked to a significantly higher mortality rate amongst adults diagnosed in the community compared to previously circulating strains.

They found that the new variant led to 227 deaths in a sample of 54,906 patients compared to 141 amongst the same number of closely matched patients who had the previous strains.
