HIV is commonly transmitted via unprotected sexual activity, blood transfusions, hypodermic needles, and from mother to child. Upon acquisition of the virus, the virus replicates inside and kills T helper cells , which are required for almost all adaptive immune responses .
At the household level, AIDS causes both loss of income and increased spending on healthcare. A study in Côte d'Ivoire showed that households having a person with HIV/AIDS spent twice as much on medical expenses as other households. This additional expenditure also leaves less income to spend on education and other personal or family investment.
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 ...
HIV, which causes AIDS, is now manageable, though there is still no cure. Now the Trump administration has put the brakes on foreign aid while alleging it's wasteful, causing chaos in the system that for over 20 years has kept millions of people alive. Confusion over a temporary waiver for PEPFAR — and the difficulty of restarting its work ...
HIV-associated nephropathy (HIVAN) refers to kidney disease developing in association with infection by human immunodeficiency virus, the virus that causes AIDS.The most common, or "classical", type of HIV-associated nephropathy is a collapsing focal segmental glomerulosclerosis (FSGS), though other forms of kidney disease may also occur.

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%.

Myocardial toxoplasmosis causes an increase in the myocardial fraction of creatine kinase (CK-MB). In situ hybridization or polymerase chain reaction studies illustrate a high frequency of cytomegalovirus and HIV-1 in AIDS patients with lymphocytic myocarditis and severe left ventricular dysfunction.
The genome and proteins of HIV (human immunodeficiency virus) have been the subject of extensive research since the discovery of the virus in 1983. [1] [2] "In the search for the causative agent, it was initially believed that the virus was a form of the Human T-cell leukemia virus (HTLV), which was known at the time to affect the human immune system and cause certain leukemias.
