EDIT: Caution! CDCC may fail in mid-term if the virus undergoes genetic mutations on his journey. But it may success even in this case. It depends on the numbers.
Concept may also fail in case of possible re-infections, see "mixed topic" below.
In the meanwhile please refer to the CCfC concept (CityConcierge for Corona)!
Now the world has seen (more or less) abrupt action for preventing the SARS-CoV-2 to do (more) harm. Now in many places there's high danger of infection and the possibility to participate in social life nearly vanished. Hearing newer reports, the measures include a high amount of privacy-opposed techniques for mass surveillance.
We now have two options:
This little article is about the second option. Terminology is:
I don't want to tell you too much prosa - here's an "FAQ" on the concept (although no-one had ever chance to ask any question at this time of writing):
Corona protective city (Cecti) has lots of not-immunized, "healthy" people. There is a medium amount of disinfectous measures which you already know from everyday use: not coughing into the public, using gloves, washing hands regulary, etc.
In case you get sick in Cecti, you and your near flatmates/friends/collegues must leave this community instantly for Ceizi. There's no excuse.
In case a person has met new friends in some event, it shall perform some balanced form of self-quarantaine for five days.
The Cecti is undergoing regular statistical memory-cell tests (which don't need to be tracable). You can assume that there are 0-10% of memory-cell pervasion across people here.
In Corona epidemic city (Ceizi) you are a bit in danger because you will be infected with the virus. But - relax, take it like holidays or a calm cure. If you are unstressed the virus will not harm you too much. And if it will - there are sufficient medical facilities which will try their best to heal you.
In this way of thinking, don't have fear to meet other people.
After having lived for a certain time span (~4 month?) in Ceizi, you are probably immune against the virus. If you are not sure, you can be tested. Now you can leave for Cozi.
Corona over city (Cozi) is a safe place - nearly everybody is immune (~85% of memory-cell pervasion). Social life is normal, and nobody has a thought about the virus. Here you can plan your (new/old?) garden, make up your worklife, go to parties, and live in peace until the next natural disaster. [EDIT]
Few people are allowed to go to Cozi and use the heard protection. But if too much people do that, Cozi isn't a safe place any more. So politics have the duty to make good decisions on whom to be allowed to go over to Cozi.
Typically this permission should be given to people in high risk groups (people which get severe diseases from SARS-CoV-2 virus)
But keep in mind that:
-> This problem is difficult to solve. You probably will have to leave the house/flat/... but maybe you can come back after city has changed it's status. (Maybe it's all over after two years)
There must be a social contract which ensures a just distribution of financial and social hardship. Of course this social contract must be designed and ratified by the people.
Yes, maybe. But until that, we must live together somehow. We humans need social proximity, and the Cecti-Ceizi-Cozi concept is a good approach. As soon as there's a vaccination, the Cecti and Ceizi people can directly enter Cozi state. (So society must somehow decide who must go to Ceizi first in a fair manner)
No, maybe not. Then it's month / years later and there's still uncertainity and social distancing and we will face at least scattered health system overload events.
Yes, it's not too unprobable that further diseases will face us. If the concept works out well for SARS-CoV-2, we have good guidelines for the next disease.
This is the second set of questions. These actually have been asked.
(self answered) I see, 3. phase is needed for the risk groups of persons which should not get infected.
Of course from an individual health point of view you can change from third to first phase. It is problematic because of bad overview possibility. Nobody will know how many of the already immunized are on which side of the fence. They will probably manque (be missing) in Cozi for heard protection.
Also it is not so convenient in Cecti (1.) compared to Cozi (3.) because of annoying hygiene rules. (even if they are not too hard). [EDIT]
Furthermore this measure prevents that Ceizi (2.) has an too bad image where "others", "ill" people shall reside but not "me". It works better if everyone goes there.
One of the main originating problems is what to do with people who have colds on a regular basis. They would go into 14-day self-quarantaine regulary and/or avoid other people and/or wear masks. It would be better for them to quickly make their way 1.->2.->3.. Others would make this way later then.
Another matter is the isolation of the absolute neccessary activities like buying food, going to dentis, .... A common strategy of the waiting withoud city-division forces lots of people and facilities towards extensive isolation measures. With CDCC concept just Cecti (1.) would have to be somewhat more hygienic, while Ceizi and Cozi (2./3.) are as indifferent as normal.
Yet another problem is the pre-planning. If you want to participate in some important bicycle tour/event/festival in summer e.g. you could already now (in spring) move to Ceizi (2.) to get risk-free in summer.
Here are creative analogue solutions to be found. When the knowledge holders of a agricultural plant have an suspicion of beeing infected the whole workforce must be more relaxed and virtually change to "Ceizi city". In other words, there must be phase 2. issued over the plant.
For preparation it may make sense to develop an exchangable farm format (EFF) so agrarian skilled people can fastly adapt onto the farm. Problem may be that this may limit a small-pieced strategy which directly addresses the local conditions. But exactly such local strategies are needed for more sustainability (humus building, water saving, biocide avoidance).
What wasn't said but should be told of:
Some scurrile side effect is that you have to keep the infection running in Ceizi (2.) - actually the infection you want to get rid of in society ;-) This is the reason why it is needed to have a transit of lots of people there. (This concept makes up just because SARS-nCoV-2 is "harmless")
An advantage of CDCC is that you don't need too many tests.
KDCD (South Korea) says that as of 10th of April 91 cases have re-tested positive after beeing discharged from isolation (thanks to newspaper "taz" for the hint) If it is possible to be re-infected this would change the game.
23. 3. 2020: initial
24. 3. 2020 early: use of "live" instead of "die" in Cozi description, add natural disaster
24. 3. 2020 late: replacement of "antibody" by "memory-cell" , FAQ2+mixed topic (german+english)
25. 3. 2020 early: clearer words to describe non-immunized persons
25. 3. 2020 late: thread -> threat... and further
1. 4. 2020 late: added relativization in consideration of the news about a genetic change of the virus
10. 4. 2020: moved from sonstiges/covid19 to sonstiges/covid19/CDCC, and clearance of two confusing numbers. Added re-infection information.
