Hi MacMan and welcome to the forum!
Haha, I never EVER touch anything that the public touch anyways but I still wash my hands a lot when I get back from shopping with my Mum just in case.
I hate how I never used to fear catching it when I was below the age of 10 but after that I can't stand it. :( I only realised I had this phobia in August this year, yet I've been afraid of being sick since I was 10. I thought I just hated being sick and that's it, never thought it was a phobia or anything.
