As we begin to understand how this virus is spread containment by neighborhood or specific City would be more appropriate. I just came from Croatia where all the buses have been shut down. The biggest problem there was that people were coming from Italy to work in Croatia causing the acceleration and spread of the virus. When you consider the all of the old Yugoslavia was smaller than the State of Arizona you can see how easily the virus has spread their. Restricting the flow of people from cities and counties could do more to stop the spread.
