New York City is the densest city in the US. The runner up is San Francisco. NYC has more than 10,000 COVID-19 deaths. As of Monday, San Francisco had 15. Not 15,000. Fifteen people. California got hit with COVID-19 first, but they didn't get hit hard. We explore why, and what places like New York can learn from their approach. On today's show, as states begin to weigh how to enter people back into the workforce, Thomas Fuller, San Francisco bureau chief for The New York Times, discusses how California is approaching the move and what New York can learn from the state and Moritz Kraemer, scholar and researcher of epidemiology at Oxford University, joins to discuss what we know about how the virus has spread worldwide.
