The UK variant has a 32-104% higher death risk than the other species
A study of more than 100,000 patients concluded that the British variant of the coronavirus represented between 32% and 104% a higher risk of death than the other variants, although the percentage of people who died over the infected remains low.
The study, published in the British Medical Journal (BMJ), was conducted on 109,812 participants, half of whom had the variant known as UK or B.1.1.7 and what was analyzed was the number of people who died within 28 days after the first positive PCR test.
The researchers found that infection with the new variant caused 227 deaths in a sample of 54,906 patients, compared to 141 of the same number of patients with other variants.

“ The increase in risk index between 1.32 and 2.04, higher than the other variables, translates to an increase from 32% to 104% in risk of death.With the most likely risk index estimated at 1.64, or a 64% increase in the risk of death, the study authors note.
They added, however, that “the absolute risk of death in this group of community-identified participants remains relatively low, rising from 2.5 to 4.1 deaths per 1,000 cases.”
In conclusion, the researchers note that the British variant “Besides being more transmissible, it appears to be more lethal.”.
“We hope this is linked to changes in its phenotypic properties due to multiple genetic mutations and we don’t see any reason why this finding would be specific to the United Kingdom,” they said.
The British variant was first discovered in the southeast of England in September 2020“
They also argued that “this development, supported by epidemiological analyzes, means an increase in the rate of patients with severe infections requiring hospital care.”
The UK variant, also known as 501Y.V1 (B.1.1.7 ratios) or VOC 20 2012/01, was first detected in southeast England in September 2020.
According to the recent report of the PAIS Project (Argentine Inter-Institutional Genetic Project for SARS-COV-2), on February 27th, this variant has already been reported in 94 countries, including Argentina, Brazil, Chile, Ecuador, Peru and Uruguay, within South America.
In Argentina, it was discovered for the first time in a sample from the end of December last year, Of an Argentine citizen in the United Kingdom who tested positive for SARS-CoV-2 upon arrival at Ezeiza airport from Frankfurt, while it was detected on February 4 in a patient residing in La Matanza who had no travel history or contact with travelers.
