Without treatment a person living with HIV can expect to live for 11 years. [6] Early testing can show if treatment is needed to stop this progression and to prevent infecting others. HIV is spread primarily by unprotected sex (including anal and vaginal sex ), contaminated hypodermic needles or blood transfusions , and from mother to child ...
HIV seeks out and destroys CCR5 expressing CD4 + cells during acute infection. A vigorous immune response eventually controls the infection and initiates the clinically latent phase. However, CD4 + T cells in mucosal tissues remain depleted throughout the infection, although enough remain to initially ward off life-threatening infections.
People living with HIV can expect to live a nearly normal life span if able to achieve durable viral suppression on combination antiretroviral therapy. However this requires lifelong medication and will still have higher rates of cardiovascular, kidney, liver and neurologic disease. [130] This has prompted further research towards a cure for HIV.
In late 2019, Gareth Thomas announced to the world that he was HIV positive and chose to do so whilst competing in a 140-mile Ironman triathlon.
The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans.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.

Infection with HIV is determined by an HIV test.As of 2021, 85% of all people living with HIV knew their status. [2]The Joint United Nations Program on HIV/AIDS (UNAIDS), Amnesty International, the Global Network of Sex Work Projects and the Global Network of People Living with HIV/AIDS, have all condemned forced HIV testing actions as infringements on human rights and conflicting with proven ...
New advancements in technology have made testing for HIV as easy as testing for pregnancy. U.K. based company, BioSure, has developed an at-home HIV test that is 99.7% accurate. The test ...
A small proportion of humans show partial or apparently complete innate resistance to HIV, the virus that causes AIDS. [1] The main mechanism is a mutation of the gene encoding CCR5, which acts as a co-receptor for HIV. It is estimated that the proportion of people with some form of resistance to HIV is under 10%. [2]
