Definition/Causes/Risk Factors

HIV stands for human immunodeficiency virus. This is a virus that attacks certain cells of the immune system. The virus enters the immune cell and hijacks it, forcing it to make new viruses. Eventually, the immune cell dies, and releases thousands of new viruses into the bloodstream, where they can attack other immune cells.

HIV is a type of virus called a retrovirus. This classification is related to the way in which the virus carries and copies its genetic material.

The virus causes a syndrome known as AIDS, or acquired immunodeficiency syndrome. AIDS occurs when the HIV virus has destroyed enough immune cells that the body is no longer able to defend itself against infections. The person is then killed by becoming infected with diseases that pose no threat at all to those with healthy immune systems. Thus, the virus doesn’t directly kill the patient, but leaves him or her vulnerable to being killed by something else. Even organisms which pose little or no threat to healthy people, such as mold, can cause deadly infections in people with AIDS. These infections are called opportunistic infections.
