The virus variant, discovered late last year, is one of several strains recently detected in countries affected by major COVID-19 epidemics. These varieties are feared to hamper efforts to contain the pandemic.
The British services, which had previously warned of the strain’s increased infectivity, said in January that the UK study said the option could lead to as much as 40 percent. higher patient mortality.
The results of one of these studies, led by researchers at the University of Exeter, were published in the medical journal The BMJ on Wednesday.
Scientists from October 2020 and January 2021 compared nearly 55,000. subjects who were infected in local communities rather than hospitals.
The subject pairs were formed based on various criteria, including age, gender, and nationality.
The study showed that those infected with the new variant of the coronavirus (B.1.1.7) had a 64% chance of dying. higher. This means that if only the B.1.1.7 virus variant spread in the population, the mortality from coronavirus infection would increase from 2.5 to 4.1 deaths per thousand cases of infection.
Simon Clarke, associate professor of cell microbiology at the University of Reading, said the increased mortality and infectivity [atmaina] it poses a great challenge for the healthcare system and decision-makers. “
“It is increasingly important that people get vaccinated when it is their turn,” he added.
Micheal Head, a global health doctoral student at the University of Southampton, said the study results reveal a risk of spreading the virus out of control.
“It just came to our attention then [sergančiųjų] COVID-19, a worrisome new strain is more likely to emerge, ”he said, adding that the strains could be more resistant to vaccines.
While most vaccine manufacturers say there is evidence that vaccines currently in use are effective against the British strain of the virus, other variants, including those that spread in South Africa, have mutations that are feared that allow the pathogen avoid the immune response of the vaccine.
