The Case for LESS Sensitive COVID Tests

Thanks to Brilliant for sponsoring this video - the first 200 people to click on will get 20% off a Premium subscription to Brilliant. This video written & produced in collaboration with Aatish Bhatia, This video is about how cheap, fast, and LESS sensitive rapid antigen tests might be better for screening (& maybe surveillance) than PCR COVID tests due to the nature of contagiousness/infectiveness at various points on the viral load trajectory of symptomatic and asymptomatic COVID sars-COV-2 carriers.
