No matter how you count the cases at the beginning or today let’s just assume that 172 and 312,249 are relatively accurate, or at least scalable. The rate of growth in confirmed infections would be 181,440% in 1 month. These kinds of numbers sell lots of newspapers and many people (whether right or wrong) now fear going outside their homes. They fear interacting on any level with loved ones, let alone strangers. Even those who are not afraid of personally becoming infected and showing symptoms are afraid of carrying the virus and then passing it on to their elders.
This is a “Crisis of Confidence” type situation. And the markets, I fear, have only begun to reflect the reality.
