The most likely mechanism of HIV transmission in the US is through unprotected sexual contact with someone who is infected with HIV, particularly among men. Other possible modes of transmission include sharing contaminated needles or syringes, mother-to-child transmission during pregnancy, childbirth, or breastfeeding, and receiving infected blood transfusions or organ transplants (though these are now rare due to screening measures). It is important to note that HIV cannot be transmitted through casual contact, such as hugging, shaking hands, sharing food, or using public restrooms.
