Solution for the contact crisis
The East Asian countries have been showing how it's done for years. Ostensibly, they were previously concerned with respiratory protection from air pollution, but since the cross-continental model couple Schröder-Kim showed how to make their own face jewellery with coffee filters that it also matches their wardrobe, it is clear: it works both ways. No fine dust, radioactive dirt particle or virus is small enough not to be kept out by fancy scraps of cloth loosely attached to the ears. As we know it from the animistic Hindu Dharma religion, demons are not able to move around corners.
Perfect protection for a perfect world
The accessories for former politicians who have fallen out of the headlines only offer effective protection against grabbing one's own face after picking at disgusting things that could get into one's nasal mucous membranes, but that's not what it's about, it's about coping with the contact crisis. A worldwide law is to be developed to be able to recognise infected people and sympathisers in time, which does not also serve any more or less useful purpose.
For the suspension of all public events, curfews and contact restrictions were well thought-out moves in the spirit of the Roman 'bread and games', but with a planning of three days, it was simply not possible to implement measures that completely covered all eventualities and could also sufficiently disregard the complex human needs.
So the world's powerful are left to reach into the bag of tricks of past generations to achieve their goals, which they continue to cleverly conceal from us. Apparently, some sovereigns pull together and initiate such crazy things as studies in laboratories, while others, when presented with the same data, prefer to launch conspiracy theories against the class enemy - makes more sense than acting in solidarity and developing a solution.
Speaking of which, what is the solution? (Warning: funny is different)
Since there was nothing comparable in any epoch of human history, neither the plague, which decimated two-thirds of the world's population in Central Europe at that time, cholera or AIDS, to make a small historical leap, so that there is still room for the side blow to the influenza virus, which causes about half a million new infections every year in the industrialised nations, most of them severe, despite possible vaccination, they are therefore rummaging in the drawer that comes closest to the current scenario: So that innocent citizens can go out on the streets again and no longer have to fear whether only spectrophobics or sympathisers are hiding behind the masks, the people who actually wanted to make themselves a respirator are called upon to attach a clearly visible Star of David to every piece of clothing at chest level instead.
It is certainly not a final solution, as it was planned almost 80 years ago, but anyone who has experienced war can appreciate the parallels when people can no longer meet, shelves in shops are empty and no one on the street can spare a friendly glance.
Surely this simple solution is more obvious than punishing violations of the ban on assembly for more than two people.
