How we come out safely from Covid-19 pandemic is not going to be easy. This one proposal by researchers seems like a good strategy for lockdown and exit, both, if the world wants to avoid certain economic meltdown. One common problem in most lockdowns: people are still connected by some daily use objects, artifacts, air, etc., in the grocery store, water foundations, shops, etc. What we now see is a nation or state base lockdowns. Exit strategy may need to involve deconstructing society into its fundamental blocks before reconstructing society from these same healed blocks. To deconstruct the research proposes identifying green zones where Covid-19 is less or safe and red zones where its unsafe or difficult to control. The green zones may be connected and the red zones would be lockdown within a town or city also. The red zones would eventually join the green network once it controls the virus spread.
Some excerpts: “In France, people are asked to stay within 1km of their homes. Although such a measure significantly slows down the spread, the virus can still travel through the entire network. In a city like Paris, two people who are 2km apart may still share the same grocery shop, and so everyone in this 10km city is connected within five degrees of separation. Instead of enforcing a radius of movement for each individual, as is the case in France, they propose that it would work better if people were allowed to move within disconnected areas, such as counties, towns, or boroughs. Obviously, such a division would be easier to enforce between separate towns than between boroughs of one single town. Division between some zones may therefore need to be legally enforced, while divisions between other zones merely recommended. This would, of course, represent a step up in state-enforced control in many countries.”

It’s a mathematical and rational approach to exit Covid-19 pandemic. But, it will likely have undesirable consequence on people as humans and humanity as we know it. We are in a dark tunnel with no end in sight. It may bring about solidarity amongst humans on earth or could increase enmity between nations and even neighborhoods and neighbors.
I think that two trends will appear. First: the formation of closed communities (communes, subcultures according to Alexander), where people know each other and trust each other. The second trend is the strengthening of borders between communes. At the borders there will be not just a gateway, but a gate equipped with thermal imagers and other medical equipment.
I think planning theories will change, and we will start with the concepts of a healthy city above all. The city must be productive, even in the most difficult scenarios, such as widespread diseases, chemical warfare, or other changes that @@@@prevent communication between humans naturally.
I think that the Nearest Neighbor analysis gives us a good tool to analyze and assess the degree of closeness since it examines the distances between each point and the closest point to it, and then compares these to expected values for a random sample of points from complete spatial randomness pattern (CSR).

Coronavirus affects people who have weakened immunity. The United States, Spain, Italy and other countries are in the first place for coronavirus infection (a coronavirus infection table is available). The exit strategy should be based on changing the zones where the person is. It is necessary to increase immunity, and its increase depends on the environment and the regulation of the internal processes of the body. What measures should society take to increase immunity? Contact restrictions are a temporary measure to stop the rapid spread of coronavirus. Strategic measures are needed to equip the external environment, which I do not observe in the plans and most likely they will not be implemented. Supporting biodiversity, regulating external and internal depression is the basis of high human immunity. Unfortunately, society does not take significant action in this direction.

We need a better balance between globalization and national self-reliance. In a globalized world, borders do not matter and countries can turn to other countries to meet their needs if faced with an internal crisis. But now, with countries struggling to provide medical equipment, borders have suddenly become important. The coronavirus crisis has reminded that the national government is still the main political and economic unit.
The post-Corona economic system must be less short-sighted and more resilient, focusing on the fact that economic globalization has preceded political globalization. Therefore, countries must work towards a better balance between enjoying globalization and the necessary degree of self-reliance.
