China reports no new coronavirus infections for the first time on March 19. The outbreak in Italy now surpasses that in China. 

The U.S. government is now shifting to social distancing as the most effective way to control the spread and away from focus on widespread testing as a containment tool. The experience in China shows social distancing works, quarantine works. Countries and regions that have neglected to do this early are the ones worst hit, including most of Europe. 

The reintroduction of the infection after its containment is addressed by quarantine and social distancing and use of masks, government disinfecting hard surfaces in all public areas, a program implemented strictly in Asian countries such as Singapore, China, Taiwan, and other Asian countries. Use of masks was common in Asian countries in earlier episodes of SARS and other epidemics, making it widely used long before this crisis. This is making a significant impact in addition to social distancing and other quarantine measures taken in China.
