Where does HIV enter in the body?

The primary route of HIV transmission is through the exchange of bodily fluids, such as blood, semen, vaginal fluids, and breast milk. The virus can enter the body through:

1. Sexual Contact: HIV can be transmitted through unprotected sexual intercourse (anal, vaginal, or oral) with an infected person.

2. Blood Transfusions or Blood Products: Before widespread HIV testing, HIV could be transmitted through blood transfusions or the use of contaminated blood products. However, with modern screening measures, this risk has been significantly reduced in developed countries.

3. Sharing Needles or Sharp Objects: HIV can be transmitted by sharing needles, syringes, or other sharp objects contaminated with infected blood. This is a common risk among people who inject drugs.

4. Mother-to-Child Transmission: HIV can be transmitted from an infected mother to her child during pregnancy, childbirth, or breastfeeding. Without proper medical care and interventions, the risk of transmission can be significant.
