On 11MAR20 there was a mutant divergence of 34.7. Both in mRNA (nucleotide) and in peptide evolution (AA).
It was found in the autopsy of a 38 year old Man from KwaZulu Natal in South Africa. What is significant is this occurred during Autumn/Fall in South Africa and the divergence is already at ~35 evolutions/mutations.
