Explanation:
There is growing evidence that a particular mutation in the coronavirus early into the pandemic made it more contagious. Now mutations in a virus by itself are not alarming — minor mutations do occur during each replication process. But a series of findings suggest that a particular mutation may have helped in the rampant spread of Covid-19.
This theory was first put forward by researchers at Los Alamos National Laboratory in May — you can read that here — but the scientific community was sceptical, arguing that the variant may have been simply lucky, rather than hold a distinct trait. But a host of new research has supported the view that the mutated virus did in fact have a distinct advantage, infecting people more easily than the original variant detected in Wuhan, China.
The mutation, known as 614G, was first spotted in eastern China in January and then spread quickly throughout Europe. Within months, the variant took over much of the world, displacing other variants. There is no evidence that the 614G mutation causes more severe symptoms, kills more people or complicates the development of vaccines.
Multiple new research from the US and UK now appear to corroborate the early findings of the team from Los Alamos. A British study by researchers from Imperial College, London, and the Institute of Evolutionary Biology, University of Edinburgh, among others, found that outbreaks grew faster when seeded by the 614G variant than when seeded by its Wuhan ancestor. Another by researchers at the University of North Carolina at Chapel Hill found that hamsters infected each other more quickly when exposed to the variant. And in a third study, the mutated variant was found to be far more efficient in infecting human bronchial and nasal tissue in a cell-culture dish than its ancestor.
How did the mutation spread? The countries shown in the graphic below reported at least five months of data since January and at least 75 sequences in one of those months.
