Christep, Thanks for the info from your site. The question I'm left with is "What is the purpose and effectiveness of the masks being worn?"
From what I've read the ones you wear all day are of no use unless you are trying to stop spreading your own infection(colds and coughs etc). the better ones as worn in hospitals are only effective until they become saturated with humidity from your breath (approx 1hr).
If this is so why are the gov guidelines not more clear on this?
Any info appreciated.
