HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS. Unlike some other viruses, the human body cannot get rid of HIV. That means that once you have HIV, you have it for life.
Only certain body fluids; blood, semen (cum), pre-seminal fluid (pre-cum), rectal fluids, vaginal fluids, and breast milk from a person who has HIV can transmit HIV. These fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the bloodstream (from a needle or syringe) for transmission to occur. Mucous membranes are found inside the rectum, vagina, penis, and mouth. Early HIV infection often times has no symptoms. The only way to know if you are infected with HIV is to be tested. Currently, there is no effective cure that exists for HIV. However, with proper medical care, HIV can be controlled.
CDC recommends that everyone between the ages of 13 and 64 get tested at least once as a part of their routine health care. People with higher risk factors, such as more than one sex partner, other STDs, gay and bisexual men and individuals who inject drugs should be tested at least once a year.
