I remember having worming pills as a precaution as a child in Australia, and was also later infected with threadworm at least once so had medicine for that. I did walk around outside without shoes a lot back then. But from what I've seen in research and been told by doctors, they see no reason to worm adults as a precaution. I'm not sure what the supposed downside is of doing it once a year or so - nasty side effects?
