Variants with a mutation known as Q677 have emerged in numerous states in the South and Southwest, with the highest concentrations in New Mexico and Louisiana
* Scientists have discovered seven coronavirus variants with nearly identical mutations to their spike proteins in the US
* Two have gained ground in Louisiana and Mississippi, but the variants, known by their 677 mutations have been spotted in numerous states
* Scientists aren't yet sure whether these variants are more infectious
* But the emergence of the same spike protein mutation in multiple places suggests it could give the virus an advantage over older variants
Scientists have discovered another seven homegrown coronavirus variants that emerged across the US, and are concerned over identical mutations seen in the 'spike' protein that could make them more infectious.
It's not yet clear whether these variants are in fact more contagious, or how common they are across the US as a whole, according to a pre-print posted to MedRxiv ahead of peer review on Sunday.
But the new variants all share a set of mutations to the critical spike protein - the same part of the virus that has mutations in the more infectious UK and South African variants.
