I went to buy something from the store today, and my cashier and a cut on her hand and also a few surrounding her nails, i also have several cuts on my hands. She brushed my hand when she was handing me my change. I am worried that i might get hiv from this person, however i did not actually touch any of her cuts with mine. Also, i don't know if that person actually has hiv..what should i do? please help i'm totally freaked out!
