Seems to be now spreading to more people in the US. (or more people are being tested due to severe symptoms, but how many more have it that have not been tested ?)
Travel abroad to places like Italy, not just China, has brought more infections back here. Since those who are infected can spread it without knowing they have it, and not showing symptoms, how does the US slow that down ? You cant quarantine for that without severely impacting the US economy, similar to what has occurred in China, and then other countries with high numbers like South Korea.
Will we suddenly see entire US cities decide to declare large quarantine zones, or encourage more voluntary self quarantine ? Large companies like Amazon are encouraging more 'stay at home' work days. How do they Decide when to do that, and for how long, and with how many ? Wuhan is still under quarantine since 3rd week of January.
Bond markets are signaling the impact of a large scale slowdown in economic activity. .9 % yield on 10 year.
