The '''Human Immunodeficiency Virus''' ('''HIV''') is the virus that causes [[AIDS]] (Formerly known as Gay Related Immunodeficiency syndrome or "[[gay plague]]"). A September 2010 report of the [[Centers for Disease Control and Prevention]] (CDC) declared : "[[Homosexuality|Gay]], [[bisexual]], and other men who have sex with men (MSM) represent approximately 2% of the US population, yet are the population most severely affected by [[HIV]] and are the only risk group in which new HIV infections have been increasing steadily since the early 1990s. In 2006, MSM accounted for more than half (53%) of all new HIV infections in the United States..."<ref>http://www.cdc.gov/hiv/topics/msm/index.htm</ref> In August of 2009, LifeSiteNews reported: "An official with the [[Centers for Disease Control and Prevention]] (CDC) announced the CDC's estimate Monday that in the [[United States]] [[AIDS]] is fifty times more prevalent among men who have sex with men ('MSM') than the rest of the population."<ref>http://www.lifesitenews.com/news/archive/ldn/2009/aug/09082609</ref>

The Virus infects and slowly kills human CD4+ helper T-Cells. With Treatment the progression of HIV infection to AIDS is slowed considerably, but may still progress. As T-cell counts fall a number of opportunistic infections can take hold and normally benign organisms can become deadly.

The '''Human Immunodeficiency Virus''' ('''HIV''') is the virus that causes [[AIDS]]. It is a lentivirus, (a type of [[Retrovirus]]). There are 2 known versions of Human Immunodeficiency Virus, both originally from monkeys, and both extremely virulent. The virus causes AIDS by infecting vital cells in the immune system, specifically the T helper cells, macrophages, and dendritic cells, without which, the immune system is rendered non-functioning. The virus itself is believed to be originally Simian Immunodeficiency Virus, that has evolved to target humans effectively. The virus is originally from [[Africa]], as bushmeat hunters were infected, and through transfer of bodily fluid to other people, eventually found itself in North America, and subsequently, the rest of the world.

A French team of researchers has been given primary credit for the discovery, although the American scientist [[Gallo]] apparently discovered it independently.
