The main ways of HIV transmission include sexual contact, blood transmission, mother-to-child transmission, and so on. 1. Sexual contact: Sexual contact between people of the same sex or different sexes can cause HIV transmission, in which male-to-male sexual contact is more likely to transmit AIDS. 2. Blood transmission: HIV can be transmitted from broken skin and mucous membranes, contact with infected blood, importation of contaminated plasma, or sharing of infected intravenous syringes by drug users. 3. Mother-to-child transmission: A mother with AIDS can pass the HIV virus to her child through the placenta. AIDS is a disease that is transmitted through blood and body fluids. Sharing utensils, respiratory droplets, insect bites, and ritual hugging and kissing have all been shown not to transmit HIV.
