New COVID-19 strain found in UK has a 64% higher death risk 

 

According to an article published on the website of the Center for Infectious Disease Research and Policy (CIDRAP) on the 10th, a British study found that among people over the age of 30, the B.1.1.7 new coronavirus variant (first discovered in the UK) died within 28 days The risk is 64% higher than the previous initial strain of the new coronavirus.

The research was led by researchers at the University of Exeter and published in the British Medical Journal (BMJ). The study involved community testing and death data of 54906 matched participants from October 1, 2020 to January 29, 2021, all of whom tested positive for the new coronavirus.

The study pointed out that compared with the previous SARS-CoV-2 strain, patients infected with the B.1.1.7 variant strain have a hazard ratio (HR) of 1.64 within 28 days after diagnosis.

Patients infected with B.1.1.7 did not have a significant increase in the risk ratio of dying within 14 days after diagnosis, but the risk ratio of dying within 15 days to 28 days after diagnosis rose to 2.40. The deaths among the participants were older than their peers, and the proportion of men was larger.

The results of the study read: “The increase in the hazard ratio is between 1.32 and 2.04, which is higher than other variants, which means a 32% to 104% increase in the risk of death, and the most likely hazard ratio is estimated to be 1.64, which means a 64% increase in the risk of death. “

The mutant strain of the new coronavirus B.1.1.7 was first discovered in the United Kingdom in October 2020 and quickly became dominant, triggering a nationwide lockdown and raising concerns about the spread and possible increase in the severity of the disease.

CNN reported that Robert Challen, the lead author of the study at the University of Exeter in the United Kingdom, said at a news conference on Wednesday: “In the community, deaths caused by the COVID-19 virus It is still a rare event, but the B.1.1.7 variant increases that risk. Coupled with its ability to spread quickly, B.1.1.7 has become a threat that should be taken seriously.”

The researchers wrote: “In addition to being more contagious, this worrying variant also seems to be more deadly. We expect this to be related to changes in phenotypic characteristics caused by multiple gene mutations. We don’t think this discovery will be limited to United Kingdom.”
