LONDON: The rapid spread of alpha variants from SARS-COV-2 through the UK autumn then driven by a large number of people infected “exporting” variants to various parts of the country, according to a large study.
Researchers, including those from Oxford University in the UK, noted that the spread of the explosive alpha variant produced not only from biological changes in viruses but also increased by “super seeding events”.
This study, published on Thursday in the journal Science, mapped the spread of variants, also known as the lineage B.1.1.7, from its origins in Kent and Greater London in November 2020 to all except five countries in the UK on January 19, January 19 this.
“In early December 2020, the Covid-19 transmission episarist in the UK shifted quickly from the northeast and northeast to London and the South, such as the Alpha variant took place,” said the main author of the author of Moritz Kraemer, from Oxford.
“When people travel from London and south east to other areas in their UK ‘Featured’ new transmission chains from the variant.
This continues as a national ‘Super’ Seeding event that does not start slowing until early January,” Kraemer said.
The researchers noted that even though the journey was locked up, after restrictions were introduced on December 20, this was compensated by sustainable exponential growth in the case of the Alfa variant.
The rapid spread of alpha variants throughout the UK caused the initial report that it could reach 80 percent more transmitting than its original tension.
This study shows that mobility significantly influences the spread and early levels of growth.
“The estimated superiority of Alpha transmission over the previous strain was initially 80 percent, but declined over time,” said Professor Oliver Pybus, from Oxford.
“We find the emergence of Alpha is a combination of genetic changes in viruses and temporary epidemiological factors.
The initial wave of the export of alpha variants to places in the UK with a low infection rate, from a large outbreak in Kent and Greater London, explaining why at first spread very quickly, “Pybus said.
The researchers said the Alfa variant did contain genetic changes that made it more transmitting, and the possibility of a variant of 30 to 40 percent more contagious from the initial tension.
“The Alpha variant began by spreading mostly in London and the South, even during November locking in England.
After this was appointed, it spread rapidly throughout the country, because the human movement increased significantly,” Verity researchers, colleagues and researchers from the University of Edinburgh, said.
“Our ability to be able to track the origins of Alfa back to the source of the point on the east of England has important implications for how new variants appear and how they will spread throughout the UK,” added the hill.
