A mutated strain of coronavirus that has decimated the US, UK and Italy is nearly 10 times more infectious than the original virus that emerged from China, a study suggests.
The potent version of SARS-CoV-2 – called D614G – has four to five times more ‘spikes’ that protrude from the viral surface allow it to latch onto human cells.
Not only does this trait make it more infectious, but it also makes the virus more stable and resilient.
