HIV Basics
HIV (Human Immunodeficiency Virus) is the virus that causes AIDS (Acquired Immunodeficiency Syndrome). HIV can be spread through:
- Contact with HIV-infected blood (for example, sharing drug needles or syringes)
- Sexual contact with people who are infected with HIV. During sexual activity, HIV can enter the body through the vagina, vulva, penis, rectum, mouth, or cuts and sores
- Breastfeeding, or during pregnancy or birth. Mothers who have HIV can pass the virus to their babies
HIV attacks the immune system, and it tries to multiply as fast as it can. As it multiplies, it attacks and destroys a special immune cell called a T-cell, or CD4+ cell. These T-cells are needed to help protect the body against infection and disease. If untreated, HIV can produce billions of new viruses every day.

Treatment for HIV can help slow the virus, keeping it under control so that the immune system can recover. This helps your body fight off infections that can lead to a diagnosis of AIDS. It's important to talk to your doctor about your treatment options for HIV.
