D614G – No evidence for increased human transmission

tatagiri: 13 hours ago

SARS-CoV-2 virus isolates from many parts of the world have a single amino acid change in the spike protein, D614G. This observation in itself doesn’t mean very much. It could be that the change arose early in the outbreak and as this virus spread to other areas it was maintained because it has no fitness cost. We call this behavior ‘founder effect’. Whether the change has been selected for – what we would call ‘positive selection’, as claimed by many virologists, needs to be proven by experiments that have not been done.
