From second waves to new variants: The progression of the COVID-19 pandemic

Published: August 12, 2021

Just over a year ago, I was joined by Julie Swann with North Carolina State University to discuss what, at that time, were fears of a second wave of the coronavirus, and to reflect on how the virus had changed nearly every aspect of our day-to-day lives, seemingly overnight.

Now nearly a year later, I am so pleased to welcome Julie back to review what has occurred since we last spoke and to discuss, almost incredulously, growing concern over not just another wave of the virus, but a new variant of the virus, the delta variant, and its impact on steps taken this spring and summer toward reopening and a return to normal.

The most important thing to know about the delta variant is that it is more infectious than the original strains of the virus. It’s actually about twice as infectious, and that’s pretty significant.
