Final answer:
The claim that HIV transmission can only occur through unprotected same-sex intercourse is false. HIV is transmitted through contact with infected bodily fluids and can be spread through heterosexual contacts, shared needles, and from mother to child, not limited to homosexual contact.
Step-by-step explanation:
The statement that HIV infection can only happen through unprotected sex with same-sex partners is false.
Human Immunodeficiency Virus (HIV) is a sexually transmitted disease that affects individuals regardless of their sexual orientation.
Transmission occurs through contact with infected bodily fluids such as blood, semen, breast milk, and vaginal secretions, not just through homosexual contact.
HIV can be transmitted through heterosexual contacts as well, and can also be spread from mother to child during childbirth or breastfeeding, or through sharing needles or syringes contaminated with the virus.
