Delta Growth

The Delta variant is changing and adds new mutations. The consensus sequence according to Pango has 30 mutations now. Notice that there are multiple definitions of Delta. The W.H.O defines the Delta differently – as Pango B.1.617.2. Pango B.1.617.2 is not Delta, but the top node of multiple lineages, also included in the Delta (AY.1, AY.2, … AY.30, …). The consensus sequence of B.1.617.2 has fewer mutations.

The real world has Pango Delta. The current Delta sequence (See the Characteristic mutations of Delta), including all the characteristic mutations, is dominant in the US, UK, and worldwide.>70% in the US
