Dr. Jay Bhattacharaya from Stanford Medicine makes his third appearance on Uncommon Knowledge in eight weeks, this time to discuss a new COVID-19 survey of Major League Baseball employees he co-authored. The survey tested more than 5,600 employees across all 26 Major League Baseball clubs across the country. The results are yet another data set showing how COVID-19 spreads across geographical and economic lines. Dr. Bhattacharya also discusses the very real health risks associated with a prolonged lockdown and answers some of the questions raised by his last survey of Santa Clara County.
