B 1 1 7 variant: Does it influence COVID-19 severity?

decreased protective effect of vaccines from severe disease The current variants of concern in the United States include the B.1.1.7, B.1.351, P.1, B.1.427, and B.1.429 variants.

SARS-CoV-2 B.1.1.7 variant The B.1.1.7 variant first emerged in the U.K. in December 2020. Preliminary studies into the variant demonstrated a potential increase in transmission, death, and hospitalization with the B.1.1.7 variant based on limited available data. The findings of two recently published studies provide additional data that differs from original studies regarding the B.1.1.7 variant.

UK COVID variant spreads faster but no evidence of worse symptoms: Study

There was no evidence found that patients infected with the UK variant had more severe disease Studies published in Lancet Infectious Diseases and Lancet Public Health have found that the UK variant of COVID-19 spreads more quickly but there is no evidence to conclusively say that symptoms were worse than original coronavirus strain. The studies found that the viral load and R-number for B.1.1.7 (UK variant of coronavirus). This indicates that it has high transmissibility. Out of the two studies, the one published in Lancet Infectious Diseases is a whole genome sequencing and cohort study. This study involved coronavirus patients admitted to University College London Hospital and North Middlesex University Hospital between November 9 and December 20, 2020.

Studies provide insights into characteristics and clinical effect of SARS-CoV-2 B 1 1 7 variant

Studies provide insights into characteristics and clinical effect of SARS-CoV-2 B.1.1.7 variant Two new studies, published in The Lancet Infectious Diseases and The Lancet Public Health, found no evidence that people with the B.1.1.7. variant experience worse symptoms or a heightened risk of developing long COVID compared with those infected with a different COVID-19 strain. However, viral load and R number were higher for B.1.1.7., adding to growing evidence that it is more transmissible than the first strain detected in Wuhan, China, in December 2019. The emergence of variants has raised concerns that they could spread more easily and be more deadly, and that vaccines developed based on the original strain might be less effective against them. Preliminary data on B.1.1.7. indicates that it is more transmissible, with some evidence suggesting it could also be associated with increased hospitalisations and deaths. However, because the variant was identified only recently, these
