Twitter is completely anti-science. There is no good scientific basis for using face masks, it is like a placebo.

The epidemic is almost over anyway, since most countries are reaching herd-immunity. We can see this in the death-rates. And this decline in deaths is the reason why these masks are introduced at this time. The epidemic is about spreading fear and not about saving grandmas.

I spoke with a nurse and he told me that there are no people being treated in my district any more. Yet the news tells us that more tests show a positive. Maybe the tests show old traces of the virus, and this means herd-immunity. Maybe the tests are just failing and give far too much positives, which that the virus is going away rapidly (this happens often during the summer with flue and cold). And maybe it means that the virus is weakened for some reason.
