Some simple science that everyone should learn:
Masks with FFP2 or N95 rating trap particles by using the electrostatic properties of the fibres in the mask.
They don't catch things like a net.
They catch things *like a magnet* - except not just metal objects. Anything tiny.
There's a bullshit bit of disinformation going round that these masks can't trap viruses because viruses are too small.
That's just wrong. It's like claiming that planes can't fly because they're not birds.
It's just wrong on so many levels.
The people who claim that masks can't trap particles that small are either:
ignorant
or
malicious
"Why you are vulnerable to other infections after Corona....
More and more people are reporting that they are constantly ill after recovering from a corona infection. One possible cause for this could be an immune system weakened by Covid-19..."
"an infection with SARS-CoV-2 may still be more problematic than previously thought, because it could trigger a long-lasting immune deficiency that makes you susceptible to other diseases."
"One indication of this are reports of people who, after recovering from a corona infection, immediately catch a cold or even get sick several times in a row. The explanation for this may be an immune deficiency triggered by covid, which could possibly last for several months."
