Caligirl80 are you in the US by any chance? or here in the UK? I ask, because a lot of what you're saying is rather geography-specific.
Hookworms are really NOT an issue with humans in the UK and children ought to be able to run around barefoot outside without contracting anything like that! I mean, I suppose ticks are a potential risk in certain parts of the UK but even then ... I just hate to think that people reading your post might stop healthy outdoor barefoot play because they think they might pick up parasites. Not a thing in the UK.
The OP is obviously talking about threadworms (called pinworms in the US) which only live in humans and are evolved to do so. You cannot catch them from pets. Tapeworms can be contracted from cats and dogs but that's a very different thing with very different symptoms, and all pets should be routinely wormed anyway.
I had a South African friend who was used to routinely (monthly) having a worm pill when she lived there as a child, and got some real Looks from her GP in the UK when she asked where she could get monthly worming pills for her kids. 
Having said that, it's so hard to get rid of threadworms that I'm beginning to think that dosing everyone up on Ovex once a month is not a bad idea, if you have young school-goers. Many people are asymptomatic so probably a lot more of us have these in our guts than we realise.
I joined this thread(worm) because my younger son seems to have brought them home again and now I have them. :-( The standard NHS advise to sterilise everything, wash all bedding and towels after every use and damp-dust your house daily for 2 weeks seems to have been formulated for people who live in sterile, featureless cubes with no Stuff and flat empty horizontal surfaces everywhere.
We will try. In the meantime, I'm actually very concerned that I have them in my urethra because it's really irritated there. Any idea if Ovex actually KILLS the buggers if they migrate into your bladder, given that it's on an entirely different system to your gut? And if not, what can I drink to flush them out?
