We must be reminded that even though HIV is mainly spread by high risk sex, it is also spread by:
1) Exposure to infected needles.
2) Blood transfusion with infected blood.
3) Organ transplant with infected organs.
4) Breast milk from infected mother to child.
Having safer sex with an effective barrier method such as condoms coupled with a faithful sex partner not only further lowers risk of spreading HIV & STDs, it also serves as an effective form of contraception.
