The coronavirus variant B.1.1.7, which was first identified in the UK, is associated with an estimated risk of 64% greater chance of dying from covid-19, suggests new research published in a report. peer-reviewed journal.


A sample of people in the UK infected with the variant appeared to be between 32% and 104% more likely to die than those infected with the previously circulating variants (i.e. about 64% more likely to die), according to the study published in the BMJ medical journal on Wednesday.

Don't let that happen

The variant was originally found to be more easily transmissible and the new data supports claims by UK officials, based on preliminary data, that the variant may also be more deadly.

Researchers from various institutions in the UK analyzed data from more than 100,000 patients who tested positive for COVID-19 between October and January, and who were monitored until mid-February.

The researchers took a close look at the tests that detected the UK variant and compared them with those of previously circulating variants.

The study showed that the new variant was associated with 227 deaths in a sample of 54,906 patients, compared with 141 deaths among the same number of patients infected with older strains.

“In the community, death from covid-19 remains a rare event, but variant B.1.1.7 increases the risk.

Coupled with its ability to spread rapidly, this makes B.1.1.7 a threat that must be taken seriously, 'said Robert Challen, lead author of the study from the University of Exeter in the UK, in a news release on Wednesday.

More research is needed to determine if similar findings would emerge among more patients from other parts of the world.

"The variant in question, in addition to being more transmissible, appears to be more lethal," the researchers wrote in their study.

'We hope this is associated with changes in its phenotypic properties due to multiple genetic mutations, and we see no reason why this finding is specific to the UK.'
