I am afraid that it doesn't matter if people wear masks or not though wearing them is a clear sign of being an obedient citizen.
Almost all systems in the world (mainly of the crowded countries or their lands are at strategic locations) are instructed about how to spread 'gradually' and 'artificially' the corona virus (or some of its equivalent man-made biological poisons). Naturally, no one can stop this diabolic international plan which is justified daily also via the system's media (of all sorts).
Those who are in high classes in any country (or serving them) have no interest to stop it (including professional doctors and their assistants). And if any of those dares revealing a full truth concerning this plan, he/she will be silenced for good, in one way or another, thanks to the very advanced technologies. Obviously, the rest of humans have no serious means to stop it in the first place; at best one can hope he/she is healthy enough to recover naturally after being infected (excluding a few biological/chemical poisons). By the way, thanks to the today's drones, spreading any gas or powder over a region is as easy as playing a computer game. But please... please... don't tell anyone about this. After all, spreading panic will not solve anything, if not aggravate the situation which is very bad already. And perhaps it is better for some people to ignore it by seeing it just a conspiracy theory.
