Some statements today said the new variant “displaced” or “out-competed” delta in South Africa. But delta had largely run its course. Prevalence was very low.
More likely the new variant emerged from some initial clusters and super-spread events — and then gained a foothold. https://t.co/2M0TAE10gz
