[3] Given Issues [1] and [2], about the only way to avoid spreading COVID-19 seems to be geographic isolation. With all of today's travel, geographic isolation doesn't work very well in practice. People need food and medical supplies. They need to keep basic services such as electricity and garbage collection operating. Suppliers of food and other services need to come and leave the area and that tends to spread COVID-19. Also, the longer a geographic area is isolated, the larger the percentage of the people within the area that is likely to get COVID-19. The problem is that the people need to have contact with others in the area for purposes such as buying food, and that tends to spread the disease.
