Yes Jane you need to stock up on that anti bac hand gel, or the dettol foam hand wash. The dettol one is just a small container that when you press the top it foams up and you rub it into your hands.
I use the dettol one a lot when I go visiting so I don't pass on anything to anyone, as I visit a lot of elderly people.

Be careful out there when you are taking your photos !
