Just to add into the mix, that I (who started this thread) have been diagnosed with COPD, so could be deemed to be particularly vulnerable to various viruses etc, but still don't feel the need to use antibacterial wipes on the handles of supermarket trolleys!
Wash your hands thoroughly before eating, and before preparing food, use separate boards for certain food items, and you should be fine!
I do however worry about situations such as Beau described, where parents are going OTT, to the extent of unrealistically trying to keep their child germ free.
