Acquired immunodeficiency syndrome (AIDS) is defined as an HIV infection with either a CD4 + T cell count below 200 cells per μL or the occurrence of specific diseases associated with HIV infection. [32] In the absence of specific treatment, around half of people infected with HIV develop AIDS within ten years. [32]
Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower ...

Criminal transmission of HIV is the intentional or reckless infection of a person with the human immunodeficiency virus (HIV). This is often conflated, in laws and in discussion, with criminal exposure to HIV, which does not require the transmission of the virus and often, as in the cases of spitting and biting, does not include a realistic means of transmission.

In July 2010, the White House announced a major change in its HIV/AIDS policy; the "National HIV/AIDS Strategy for the United States" stated that "the continued existence and enforcement of these types of laws [that criminalize HIV infection] run counter to scientific evidence about routes of HIV transmission and may undermine the public health goals of promoting HIV screening and treatment."
Lentivirus is a genus of retroviruses that cause chronic and deadly diseases characterized by long incubation periods, in humans and other mammalian species. [2] The genus includes the human immunodeficiency virus (HIV), which causes AIDS.
