I know washign with soap and water is the No1 best way to ensure hands are free of norovirus but for when we are out and about it's not always possible to wash your hands or if you do, you can't help but touch a number of things between drying them and picking up your food so for added security out of the house i always use an anti-noro hand sanitiser too - they normally sting like mad and dry your hands out though, but I have found a really nice one in Boots called Mentholatum Response Beta, I think it may have been mentioned on here before but I was never 100% sure it killed noro but I rang them up this morning and they've sent me all the data sheets and certificates proving that it does.

It's not got the usual benzy stuff in and is also alcohol, paraben and fragrance free too.
