The British version was around 40-70 percent more transmissible than previously dominant versions, according to scientists.

According to a recent report published in the medical journal The Lancet Infectious Diseases on Monday, an extremely infectious version of Covid-19 has been first reported in Britain, which doesn't quite cause more serious disease in hospitalized patients.

According to the US Centers for Disease Control and Prevention, the strain is known as B.1.1.7, was discovered first in Britain late last year and has since been the most widespread in the United States.

The study compared results in patients infected with B.1.1.7 or other variants, who were admitted to British hospitals in the month of November and December last year. Patients with B.1.1.7 and other variants had no different chances of serious illness, death, or any other health implications, according to the researchers.

The researchers wrote in the report, "Our data, within the background and the limitations of a real-world study, provide initial affirmation that the intensity in hospitalized patients with B.1.1.7 is not vastly different from the intensity for those who are not infected with it."

Vaccines are likely to be effective against the British strain, according to a different report published in The Lancet Public Health medical journal. It is because there was no significant rise in latent infection incidence as compared to non-UK versions. The British version was around 40 percent to 70 percent more transmissible than previously dominant versions of the Covid variants, according to the reports by British scientists.
