What is HIV?
HIV stands for human immunodeficiency virus. It is the virus that leads to AIDS. HIV is a form of retrovirus. There is usually a long interval between the initial infection and the onset of symptoms.
When you are infected with the virus, you are referred to as HIV positive. The infection enters the bloodstream through mucous membranes or blood-to-blood contact. Today, there are a number of treatment options available to people with AIDS. One treatment is zidovudine, or AZT. Zidovudine can affect the bone marrow and cause anemia.
