COVID-19 Update: The Delta Variant

What we *think* we know about the Delta variant

The Delta variant is now the dominant strain of COVID-19 in the US, Texas and Austin. The Delta variant was first seen in India in late 2020 (note that this pre-dates all vaccines, as the first vaccines were administered in India in January 2021). Delta has been responsible for unusually aggressive, fast-moving, and deadly waves of COVID-19 in India, the UK and now North America.

This new wave of COVID-19 should be taken seriously, since in many ways it is significantly worse than the original strain we dealt with in 2020 and the first half of 2021.
