We have reusable N95 mask, not cheap
And I think that using them is a good idea.
But I don't think it's remotely right to insist that one group of society must be masked, or isolated.
Wearing ordinary masks reduced the chances of everyone and anyone getting covid. We all know that it's eccentric in how it makes some people with no risk factors very ill indeed, even if they have been vaccinated.
It's a question of basic altruism - do we make essential indoors public spaces as safe as possible (public transport, healthcare settings, pharmacies and essential retail) leaving the fun stuff for the healthy only.
Or do we also remove essential services from the 'safe as possible' list.
Anyone could get covid really badly so - by following the logic of the OP - everyone should be wearing high grade masks. Then we could all do things safely.
Oh, but it's horrid, is not what I want, I can't tolerate one, I can't wear one at all. Good points, and just as true of the CEV and CV of anyone else.
But if everyone wore masks in certain indoors circumstances, then the risk pattern changes in a way that benefits everyone, and does not put yet another burden of the CEV who have had a really shitty time of it all along, are missing out on so much that opens up this summer anyhow, and are now being 'helpfully' told that if you just spend (possibly more money than you have) on better masks then you can stop whinging.
Do people really think we're all so thick that we haven't looked at what grade mask to wear in various circumstances?
