The more transmissible type of coronavirus was first recognized in Britain and has a “much higher” mortality rate than previous versions of the virus, according to New study Published by the British Medical Journal, in the latest evidence of its most ferocious nature.
Variant B.1.1.7 was detected in southeast England in the fall and has since spread to more than 100 countries, with experts saying it Up to 70 percent more contagious From the original strain.
The study analyzed mortality rates among people with both B.1.1.7 and other variables from October to January, matching patients by gender, race, location, and timing of their positive test. It found that individuals infected with the more infectious variant were 32 percent to 104 percent more likely to die than those who previously contracted the cyclic variant.
“We see no reason why this finding is specific to the United Kingdom,” the study authors wrote. “The type of anxiety, in addition to being more transmissible, appears to be more lethal.”
Of the 54,906 Covid-19 patients infected with the new variant, 227 people have died. Among the same number of patients with other variants, the researchers counted 141 deaths.
“Coupled with its ability to spread rapidly, this makes B.1.1.7 a threat that must be taken very seriously,” Reuters quoted Robert Chale, a researcher at the University of Exeter who co-led the research, said:
The study confirms early work indicating the more lethal nature of the variable, including Prime Minister Boris Johnson’s announcement in January and The study was released in February Which indicates that it was 30 to 70 percent more lethal.
The variable “is associated with an increased risk of hospitalization and death compared to infection” with other forms of the virus, according to the latest study, drawn from multiple databases across the country.
Experts believe the variable is leading to an increase in the number of infections across Europe, including in places with high rates of infection such as the Czech Republic, Hungary and Poland.
The study did not state why the variant appeared to be more lethal.
