Bill Gates explains how the United States can safely ease coronavirus restrictions

The ability for parts of the United States to safely and effectively begin to lift coronavirus restrictions will depend on the country's capacity to aggressively test for and trace new cases of the virus, Bill Gates told CNN's Fareed Zakaria Sunday. His comments come as several US states prepare to ease social distancing and stay-at-home restrictions this week, despite warnings from health researchers that no state should reopen before May 1. Meanwhile, the total number of reported coronavirus cases in the United States is nearing 1 million, and more than 54,000 Americans have died.
