Recent reports of a variant from South Africa suggests it transmits more easily than the UK variant.  Both usually have 3 amino acids deleted from the Spike protein as well as RBD mutation N501Y and G clade mutation D614G.  The Spike deletion in South Africa (L242 A243 L244) is also in a recently deposited (at GISAID and Genbank) isolate collected on July 3 in Florida, USA/FL-BPHL-2075.  This isolate only has one additional Spike non-synonymous change, D614G
