To put it simply, most people infected by the virus never get sick at all or present only mild symptoms. Protocol doesn’t subject them to testing. Indeed, most infected people wouldn’t even bother to seek it. So, how many North Carolinians truly are infected? We need to think more broadly. According to University of Chicago professor Casey Mulligan, a rough estimate of the cost of the current lockdowns nationwide is about $20 billion a day in lost economic production. On a proportional basis, that would translate to $540 million per day in North Carolina.
