A study showed that the new Covid-19 variant was first discovered in the UK, developed rapidly, spread more easily than other variants, and affected a larger proportion of people under the age of 20.
This research is a joint effort of scientists and researchers from Imperial College London, University of Edinburgh, Public Health England, Wellcome Sanger Institute, University of Birmingham and the COVID-19 Genomics Alliance.
According to CNN, as of December 30, at least 27 countries (Hong Kong and Taiwan) have reported cases of the new virus strain.
“All analyses agree that VOC [the Variant of Concern or new variant] Has great transmission advantages. It added that compared with other variants of the virus, the difference in the number of reproduction of mutations is 0.4 to 0.7 higher. The number of replications reflects the number of individuals that an infected person transmits the virus to.
According to this research, the number of copies of the new version is currently between 1.4 and 1.8.
“These analyses have provided information for the UK government’s plans in recent weeks, showing that the new variant B.1.1.7 of interest has a higher transmission capacity than the previous SARS-CoV-2 virus circulating in the UK,” Professor Neil Ferguson Said. Said Imperial College London.
The study also said that although people under the age of 20 account for a higher proportion of new virus mutation cases, it is still too early to determine the cause.
Ferguson said that because the new variants are easier to spread, it will be more difficult to control. He emphasized the “urgency of launching a vaccine as soon as possible.”
Dr. Erik Volz of Imperial College London said: “All viruses will evolve, and they will rarely be changed in a way that requires us to re-evaluate public health policies,” noting that experts have found out. The overwhelming evidence suggests that the spread of this virus has changed. The B.1.1.7 variant should be considered when planning a new Covid-19 response.”
The UK will launch the Oxford/AstraZeneca vaccine on Monday, which was approved for use on Wednesday.
