Delta Variant now accounts for 83% of U.S. COVID-19 Cases. https://covid.cdc.gov/covid-data-tracker/#variant-proportions (Go to control bar above the chart, and select “Nowcast On”)
That bar chart visibly shows the exponential increase of Delta as a percentage of newly sequenced cases as a reflection of its infectiousness.
Herd immunity… here we come. Glad to not see a coinciding rapid increase in deaths.
