It is nearly impossible to transmit HIV through casual contact. 

HIV is not transmitted through casual contact such as hugging, shaking hands, sharing utensils, or kissing. It is only transmitted through specific bodily fluids including blood, semen, vaginal fluids, breast milk, and rectal fluids, and requires direct exchange with these fluids such as through sexual contact, sharing of injection needles, or transmission from mother to child during childbirth or breastfeeding.
