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]
The infection progresses to AIDS when the count falls below 200 CD4 T cells/μL, at which point opportunistic infections can be lethal. At this stage, an infected person has 2-3 years of life expectancy. The use of antiretroviral therapy (ART) can greatly slow the progression of the virus to AIDS.
And antiviral treatment has changed HIV from a death sentence in the early '80s to people with HIV now having a normal life expectancy. People with HIV on antiviral drugs can safely have babies ...
Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. [3] Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. [4]

When the HIV infection becomes life-threatening, it is called AIDS. People with AIDS fall prey to opportunistic infections and die as a result. [60] When the disease was first discovered in the 1980s, those who had AIDS were not likely to live longer than a few years. There are now antiretroviral drugs (ARVs) available to treat HIV infections.
HIV infection is becoming endemic in sub-Saharan Africa, which is home to just over 12% of the world's population but two-thirds of all people infected with HIV. [38] As of 2022, it is estimated that the adult HIV prevalence rate is 6.2%, a 1.2% increase from data reported in the 2011 UNAIDS World Aids Day Report.
Following infection with HIV-1, the rate of clinical disease progression varies between individuals.Factors such as host susceptibility, genetics and immune function, [1] health care and co-infections [2] as well as viral genetic variability [3] may affect the rate of progression to the point of needing to take medication in order not to develop AIDS.
