Imagine rubbing your eyes - and waking up in a world without corona.

Suddenly you can leave the house without putting on a mask.

You can meet friends in the bar in the evening.

Even your children, if you have any, can go back to school.

Because you are lucky: you live in the “green zone”.

There is only one catch: you are not allowed to leave this zone. Unfortunately, the whole world is not exempt from the coronavirus, as viruses - they are adaptable and like to mutate - can never be completely eradicated. Over there, in the “red zone”, there are new infections: there are draconian curfews, infected people are isolated in guarded hotels, and only people living alone are allowed to receive visitors.
