A reality check on the coronavirus outbreak

We're due for another coronavirus reality check on what we know and how we know it. Dr. Michael Mina, an infectious disease specialist at Harvard's T.H. Chan School of Public Health, speaks with The World's host Marco Werman about the latest understanding of how the virus spreads, how it incubates and how deadly COVID-19 is compared to other respiratory diseases. And, Amazon founder Jeff Bezos says he’ll start handing out $10 billion worth of grants to fight climate change. Also, in Thailand, snails have long been seen as creepy pests that ravage crops. Now a beauty craze sweeping Asia — rubbing collagen-rich snail excretion on your face — has radically hiked the value of snails.
