The effects of the delta variant have changed both the public and governmental attitudes away from a sense of being nearly over this.
North American and European Nations appear to have run into a wall on vaccination acceptance at about 50% of the population fully vaccinated.
In the US, over half of all new COVID cases appear to be due to the Delta variant and that will likely continue to increase.
As of this week, the Delta variant has become the predominant strain in the US, just as it is in the UK and in nearly all of Europe.
The Delta variant mutation caused a specific fold in the geometry of the spike protein that causes it to bind to cells more efficiently.
In the United States, COVID-19 case rates have decreased to three cases per hundred thousand per day.
Over the last few days, estimates are that the delta variant is responsible for 10% of all new cases in the United States.
In the US, over the last week, the rate of decrease in numbers of cases and deaths has fallen, and 20 states have seen an increase in cases.
