HIV Myth 3: 'I Donât Need to Worry â HIV/AIDS Only Infects Gay Men'. This couldn't be further from the truth. HIV is transmitted through an exchange of body fluids, specifically semen, vaginal fluids, breast milk, blood or pre-ejaculatory fluids. Most men become HIV-positive through sexual contact with other men.
HIV is a virus which is most commonly passed on by sexual contact. HIV attacks cells of the immune system. Untreated, the immune system weakens so that the body cannot defend against various bacteria, viruses and other germs. This is when AIDS (commonly now called late-stage HIV infection) develops. However, early detection and treatment with antiretroviral therapy (ART) means that people living with HIV can lead active, healthy lives. However, they may have side-effects from the treatment.
