An Evolutionary Biologist Looks at Variants, and the Role of Rapid Testing in Covid


This week, we cover two crucial issues in Covid: variants and testing. The highly infectious Delta variant has been responsible for changing the trajectory of Covid over the past six months.

In the first segment, evolutionary biologist Paul Turner of Yale will describe how and why variants happen, whether Delta was a surprise, and what the future may hold in terms of additional variants.

In the second segment, Harvard epidemiologist Michael Mina returns to Medical Grand Rounds. Mina is the nation’s most prominent advocate for focusing on testing as a key prevention and mitigation strategy.

In the past few months, his calls have generated significant traction in the Biden administration. We’ll discuss the role of testing – particularly rapid testing – in creating safe spaces in businesses and schools, and where testing fits into our overall Covid strategy. The session is moderated by UCSF Department of Medicine Chair Bob Wachter.
