A new variant of Coronavirus emerged in the United Kingdom last year. Concerns have been raised about faster infection rate, more deadly symptoms, and the ability of a new strain to dodge the immunity provided by Covid-19 vaccines. Two new studies have found no evidence that the UK variant caused more severe symptoms of the disease.

The study analysed a bunch of Covid-19 patients who were admitted between November 09 and December 20 last year. The team compared the behaviour of the virus among patients who were infected with the B.1.1.7 variant and those patients who had been infected with earlier prevalent Covid-19 virus strains.

A total of 341 patients were analysed as part of the study out of which 198 had got infected with the B.1.1.7 variant whereas 143 had a non-B.1.1.7 infection. The share of patients who became severely ill or succumbed to the disease was roughly the same in both sets of patients. While 36 percent of the B.1.1.7 infected patients fell severely ill and died, the share of non-B.1.1.7 infected patients who got severe symptoms and died was about 38 percent.

So far as the transmission rate of the new variant is concerned, the study relied on the RT-PCR testing of patients infected by the new variant and found that the viral load was much higher as compared to earlier variants. The researchers also found that the B.1.1.7. infection patients had more viral load in their swabs as compared to the swabs of non B.1.1.7. Covid patients.
