Prompted by having just seen a picture in a newspaper of a man on the tube wearing breathing apparatus but with bare hands, which seems a bit pointless because if he has small cuts on his hands could catch it through those anyway.
Use of antibacterial hand-gel in the quantities needed for it to be effective, will irritate many people's hands, meaning that they are then actually more likely to catch it though irritated skin.
It's winter and really easy just to put a pair of woolly gloves on when you go out.
