HIV is probably directly responsible for a substantial loss of weight (AIDS wasting) in some people. Wasting in people with AIDS may also be caused by a series of infections or by an untreated, persistent digestive tract infection.
According to the Joint United Nations Programme on HIV/AIDS (UNAIDS),  worldwide in 2015, approximately 36.7 million people (1% of the global adult population aged 15-49 years) were infected with HIV, a decline from 2006 (39.5 million reported at that time). UNAIDS estimates that approximately 2.1 million people were newly infected with HIV and that 1.1 million people died of AIDS in 2015, both statistics showing a decline over time.

In February 2016, Jordon suddenly found himself too weak and tired to attend the community-college classes he had enrolled in; he could hardly lift his head from his mother’s couch. He wasn’t accustomed to being sick and had tested negative for H.I.V. just five months before, so thinking he had a bad cold, he waited weeks before his family forced him to go to the emergency room at a hospital in his small town, where he was tested again. “The doctor said to me, ‘Your H.I.V. is so bad — how could you not know?’ ” Jordon recounted through tears. He ended up in intensive care for three weeks. “I honestly didn’t believe it.” He paused and then added quietly, “It was the worst day of my life.”
In the United States, 1.2 million people aged 13 years or older were estimated to have HIV infection in 2012. About 12.8% of them do not know they have HIV infection. About 50,000 new cases are estimated to occur each year in the United States. Most new infections occur in gay and bisexual men, and black men and black women are disproportionately affected (see also HIV in the United States: At A Glance).

The World Health Organization (WHO) has issued recommendations regarding nutrient requirements in HIV/AIDS. A generally healthy diet is promoted. Dietary intake of micronutrients at RDA levels by HIV-infected adults is recommended by the WHO; higher intake of vitamin A, zinc, and iron can produce adverse effects in HIV positive adults, and is not recommended unless there is documented deficiency. Dietary supplementation for people who are infected with HIV and who have inadequate nutrition or dietary deficiencies may strengthen their immune systems or help them recover from infections, however evidence indicating an overall benefit in or reduction in mortality is not consistent.
In April 2011, he embarked on tour of his one-man show, “My Violent Torpedo of Truth/Defeat Is Not an Option.” The first show, in Detroit, went off the rails quickly. “Early in the evening, before the crowd turned sour, there was a creepy atmosphere that suggested group indoctrination into a cult,” said a Hollywood Reporter review. And that was before the booing and shouts of “You suck” started. He changed the style to a Q&A for the second show, but the tour never really caught fire.

Few viruses produce toxins, although viral infections of bacteria can cause previously innocuous bacteria to become much more pathogenic and toxic. Other viral proteins, such as some of the human immunodeficiency virus, appear to be actively toxic, but those are the exception, not the rule.
HIV influences both the epidemiology and the clinical features of many other infectious diseases, malignancies and other illnesses (e.g. renal disease) (see Chapter 10).47 In HIV-infected patients, immunodeficiency increases the risk that atypical (opportunistic) pathogens will result in clinical illness, and is associated with atypical presentations of some diseases. In addition, HIV-infected patients frequently present with multiple pathologic processes simultaneously, making decisions regarding empiric treatment very challenging. We describe the relationship between HIV and three common infectious diseases that have complex and important interactions.
Macrophages and dendritic cells seem to be able to harbor replicating virus without necessarily being killed by it, and are therefore believed to be an important reservoir of infection, as well as a means of spreading virus to other tissues such as the brain. Although the function of macrophages as antigen-presenting cells does not seem to be compromised by HIV infection, it is thought that the virus causes abnormal patterns of cytokine secretion that could account for the wasting that commonly occurs in AIDS patients late in their disease.
Acquired immunodeficiency syndrome (AIDS) is defined in terms of either a CD4+ T cell count below 200 cells per µL or the occurrence of specific diseases in association with an HIV infection. In the absence of specific treatment, around half of people infected with HIV develop AIDS within ten years. The most common initial conditions that alert to the presence of AIDS are pneumocystis pneumonia (40%), cachexia in the form of HIV wasting syndrome (20%), and esophageal candidiasis. Other common signs include recurring respiratory tract infections.
This period is sometimes called asymptomatic HIV infection or chronic HIV infection. During this phase, HIV is still active but reproduces at very low levels. People may not have any symptoms or get sick during this time. For people who aren’t taking medicine to treat HIV, this period can last a decade or longer, but some may progress through this phase faster. People who are taking medicine to treat HIV (ART) the right way, every day may be in this stage for several decades. It’s important to remember that people can still transmit HIV to others during this phase, although people who are on ART and stay virally suppressed (having a very low level of virus in their blood) are much less likely to transmit HIV than those who are not virally suppressed. At the end of this phase, a person’s viral load starts to go up and the CD4 cell count begins to go down. As this happens, the person may begin to have symptoms as the virus levels increase in the body, and the person moves into Stage 3.
The size of the proviral reservoir correlates to the steady-state viral load and is inversely correlated to the anti-HIV CD8+ T-cell responses. Aggressive early treatment of acute infection may lower the proviral load, but generally, treatment in newly infected (but postseroconversion) patients yields no long-term benefit.
