What is HIV?
Human Immunodeficiency Virus (HIV) is the virus that causes AIDS. HIV harms the body’s immune system by attacking certain kinds of cells, known as helper T cells or CD4 cells, which defend the body against illness.
What is AIDS?
AIDS, or Acquired Immunodeficiency Syndrome, occurs when an individual's immune system is weakened by HIV to the point where they develop any number of diseases or cancers. An individual with HIV will also be considered to have progressed to an AIDS diagnosis if their immune system, as measured by their T-cell (or CD4 count) falls below a certain level.

What is the difference between HIV and AIDS?
HIV is the virus that causes AIDS, the most advanced stage of HIV disease. A weakened immune system caused by HIV will allow opportunistic infections (OIs) to develop. A healthy immune system would normally fight off these infections while an HIV-weakened immune system is susceptible.
How do you get HIV?
In the United States, most people get HIV through unprotected sex, including vaginal, anal and oral sex, and through injection drug use. Certain bodily fluids including blood, pre-cum, semen, and vaginal secretions, spread HIV. An HIV infected woman can pass HIV to her baby through pregnancy or delivery, and also through breast milk. According to the U.S. Centers for Disease Control and Prevention contact with saliva, tears, or sweat has never resulted in someone getting HIV. You cannot get HIV through casual contact such as hugging or shaking hands.
How can I tell if I'm infected with HIV?
The only way to determine for sure whether you are infected is to be tested for HIV. You cannot rely on symptoms to know whether or not you are infected. Many people who are HIV positive do not have any symptoms for many years.
How do I prevent getting HIV?
There is no cure or vaccine for HIV, but it is preventable.

What is the connection between HIV and other sexually transmitted diseases?
Having a sexually transmitted disease (STD) can increase a person's risk of becoming infected with HIV. Having STDs that can cause open sores, such as herpes, is especially risky. STDs that do not cause open sores also pose a threat.
