We are being told not to buy the most effective type of masks as the nhs needs them.
That means whatever face covering you use will not be as effective.
The virus is so small it apparently flies straight through fabric. Onto the wearers face in these masks or scarves.
When it’s the wearer breathing out more particles are weighted down by dampness and more stay in the mask. More not all.
So both wearers need to stay as far away as possible to avoid potentially infected droplets so small you can’t see them but are breathing them out into the air through the covering all the time. That’s why there’s the the whole 2m thing.
Nobody has arms 2m long do haircuts are too risky really.
It’s people who haven’t read up on masks and face coverings that have delayed the introduction of face coverings.
Because people feel the second the have a mask on they are invincible. This terrifies the government because once they have a face covering they will be out at friends houses ‘in ok I have a mask on’ visiting relatives ‘im ok I have a mask on’ visiting elderly parents for a social call ‘I’m ok I have a mask on’ etc. Potentially spreading the virus which they may not know they have as they are symptomless.
We have to remember that a mask or face covering can’t protect you. It can help you not infect others. It’s for their benefit not yours.
