I work in a healthfood store. Today a woman came into the store and said that she was dealing with a major pin worm infestation and had been dealing with repeated infestations in her home. She had scalp sores, etc. and was asking for a natural remedy. I gave her a few things, Tea Tree Oil, Wormwood, Kyolic garlic, based on some reading that she had done. She was touching everything in site and testing makeup, and I briefly brushed against her coat. I am concerned that she has infected the store and was wondering if I have to be concerned about having them because I came incontact with her. I removed the makeup items that she used so that other customers could not use them. Is there anything else I should do?
