Bill Gates has been warning about the threat of a pandemic for years and his foundation has invested $100 million dollars to respond to the coronavirus. The billionaire philanthropist talks with "CBS This Morning" co-host Anthony Mason about why we currently need “strong isolation measures on a countrywide basis,” how it could be “years” before the U.S. economy gets back to where it was before and why he thinks “for the next one, we will be far more ready than we were for this one.” Gates adds, “everybody who's lived through this will view this as a dramatic, scary part of their life. And it will affect their concerns and how they look at things for the rest of time.”
