Hi: Great question :)
You can not get tapeworm by them "traveling onto you, or by touching them" The only way you can get them is the same way your pet got them...by ingesting a flea. I am providing you with a fabulous link to read all about tapeworms and how to treat them for your pet. Please consider a monthly topical flea preventative for your pet to limit the possibility of tapeworm. Good luck
