If the other person has AIDS, and even if there is skin contact with a healthy person, but there is no breakage on both sides of the skin contact area, there is no possibility of contracting AIDS. Unless there is a break in the skin of both parties in contact and there is bleeding, there is a possibility of HIV infection, but the probability of this is very low. In fact, there are three main modes of HIV transmission: sexual contact, vertical transmission from mother to child, and blood transmission. Blood transmission is usually through blood transfusions and drug use, especially injection drug use, where contaminated needles are used to produce infection.
