While there is no cure or vaccine for HIV, antiretroviral treatment can slow the course of the disease and enable people living with HIV to lead long and healthy lives. [ 5 ] [ 12 ] An HIV-positive person on treatment can expect to live a normal life, and die with the virus, not of it.
HIV is an acronym for human immunodeficiency virus, which is the virus that causes AIDS (acquired immunodeficiency syndrome).Contracting HIV can lead to the development of AIDS or stage 3 HIV, which causes serious damage to the immune system.
The management of HIV/AIDS typically involves the use of multiple antiretroviral drugs. In many parts of the world, HIV has become a chronic condition, with progression to AIDS increasingly rare. HIV latency and the resulting viral reservoir in CD4 + T cells, dendritic cells, and macrophages is the main barrier to eradication of the virus. [19 ...
Later it leads to even AIDS dementia complex. The CD 4-gp120 interaction (see above) is also permissive to other viruses like Cytomegalovirus, Hepatitis virus, Herpes simplex virus, etc. These viruses lead to further cell damage i. e. cytopathy.
In 2022, an estimated 39 million people around the world were living with HIV, according to UNAIDS, the United Nations AIDS program. HIV can progress to AIDS if left untreated.
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%.

HIV/AIDS denialism is the belief, despite conclusive evidence to the contrary, that the human immunodeficiency virus (HIV) does not cause acquired immune deficiency syndrome (AIDS). [1] [2] [3] Some of its proponents reject the existence of HIV, while others accept that HIV exists but argue that it is a harmless passenger virus and not the ...
HIV-2 has been found to be less pathogenic than HIV-1. [36] The mechanism of HIV-2 is not clearly defined, nor the difference from HIV-1, however the transmission rate is much lower in HIV-2 than HIV-1. Both viruses can lead to AIDS in infected individuals and both can mutate to develop drug resistance. [34]
