In mid-2017, 20.9 million people living with HIV were receiving ART globally. In 2016, a global ART coverage of 53% of adults and children living with HIV was reached. However, more efforts are needed to scale up treatment, particularly for children and adolescents. Only 43% of them were receiving ARVs at the end of 2016 and WHO is supporting countries to accelerate their efforts to timely diagnose and treat these vulnerable populations.

Bangui definition A points-based system used to define AIDS in countries where HIV testing is not available. It was developed by workers from the CDC and WHO at a conference held in Bangui, Central African Republic, in 1985, and gives the most points for severe weight loss, protracted asthenia, recalcitrant fever and diarrhoea. AIDS is diagnosed with scores of 12 or more.

Since then, H.I.V. has been transformed into a treatable condition, one of the great victories of modern medicine. In 1987, the F.D.A. approved AZT, a cancer drug that had never gone to market, for use in H.I.V. patients. At first, it was extortionately priced and was prescribed in high doses, which proved toxic, provoking protest from the gay community. But AZT was able to insinuate itself into the virus’s DNA as it formed, and later it was used in lower doses. Scientists have now developed more than thirty antiretroviral medicines that stop H.I.V. from reproducing in helper T cells.

HIV-positive women who might become pregnant should talk to their provider about the risk to their unborn child. They should also discuss methods to prevent their baby from becoming infected, such as taking antiretroviral medicines during pregnancy.

Key populations are groups who are at increased risk of HIV irrespective of epidemic type or local context. They include: men who have sex with men, people who inject drugs, people in prisons and other closed settings, sex workers and their clients, and transgender people.

HIV produces cellular immune deficiency characterized by the depletion of helper T lymphocytes (CD4+ cells). The loss of CD4+ cells results in the development of opportunistic infections and neoplastic processes.

Newer point-of-care tests using blood or saliva (eg, particle agglutination, immunoconcentration, immunochromatography) can be done quickly (in 15 min) and simply, allowing testing in a variety of settings and immediate reporting to Positive results of these rapid tests should be confirmed by standard blood tests (eg, ELISA with or without Western blot) in developed countries and repetition with one or more other rapid tests in developing countries. Negative tests need not be confirmed.

The only drug in this class is T-20, which is administered as a twice-daily subcutaneous injection. The most common side effects are redness and pain at the site of injection. Rarely, infection can occur at the injection site. There also are reports of generalized allergic reactions.

Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was originally discovered (and initially referred to also as LAV or HTLV-III). It is more virulent, more infective,[93] and is the cause of the majority of HIV infections globally. The lower infectivity of HIV-2 as compared with HIV-1 implies that fewer people exposed to HIV-2 will be infected per exposure. Because of its relatively poor capacity for transmission, HIV-2 is largely confined to West Africa.[94]

People who already have a sexually transmitted infection, such as syphilis, genital herpes, chlamydia, human papillomavirus (HPV), gonorrhea, or bacterial vaginosis, are more likely to acquire HIV infection during sex with an infected partner.

Toxoplasmosis. This potentially deadly infection is caused by Toxoplasma gondii, a parasite spread primarily by cats. Infected cats pass the parasites in their stools, which may then spread to other animals and humans. Seizures occur when it spreads to the brain.

Humoral response to HIV. The humoral immune response occurs later in infection; therefore, the level of antibodies during the acute infection is very low. Non-neutralising antibodies to structural proteins (i.e. P17 and P24) are first to appear and generally do not persist. Later neutralising antibodies specific to proteins, involved in the entry of the virus into the cells, will be generated. These antibodies are specific to: (1) the variable region of gp120 (V3); (2) CD4 binding sites and chemokine receptors (i.e., CXCR4 and CCR5); (3) the transmembrane protein gp41. Potent neutralizing antibodies have been shown to play a major role in controlling HIV infection in a few symptom-free HIV+ individuals who maintain high level of CD4+ T cells and low viral load.

One of the problems with finding a cure is that the virus can persist in cells throughout the body and potentially hide in areas that are difficult for drugs to reach, like the brain. New research is helping us understand how to effectively treat viruses in these secluded areas of the body. In addition, those infected cells that persist in the body are being studied to determine how they can be stimulated to produce virus and/or be targeted for clearance from the body by novel therapies.

No firm evidence has shown that the initiation of therapy early in the asymptomatic period is effective. However, very late initiation is known to result in a less effective response to therapy and a lower level of immune reconstitution.

Although widely used, alternative or complementary medications, such as herbal ones, have not been proven to be effective. According to some limited studies, mineral or vitamin supplements may provide some benefits in overall health. It is important to discuss these options with a healthcare provider because some of these options, even vitamin supplements, may interact with ARVs.

Once infection has progressed to AIDS, the survival period is usually less than 2 years in untreated patients. Persons in whom the infection does not progress long-term may not develop AIDS for 15 years or longer, although many still exhibit laboratory evidence of CD4 T-cell decline or dysfunction.

These symptoms can come and go or get progressively worse. If you’ve been exposed to HIV, you may also have been exposed to other sexually transmitted diseases (STDs). Men are more likely than women to notice symptoms like sores on their genitals. But men typically don’t seek medical care as often as women.

With the numbers of those who acquired their infections heterosexually there has been an decrease in the number of women diagnosed. The male:female ratio for all new infections diagnosed in 2008 was about 1.6:1 whereas in 2012 it was 2.6:1.[9]

Treatment recommendations for children are somewhat different from those for adults. The World Health Organization recommends treating all children less than 5 years of age; children above 5 are treated like adults.[163] The United States guidelines recommend treating all children less than 12 months of age and all those with HIV RNA counts greater than 100,000 copies/mL between one year and five years of age.[164]

As soon as you’re infected with HIV, it starts to reproduce in your body. Your immune system reacts to the antigens by producing antibodies. The time between exposure to HIV and when it becomes detectable in your blood is called the HIV window period.

Due to their nonspecific character, these symptoms are not often recognized as signs of HIV infection. Even cases that do get seen by a family doctor or a hospital are often misdiagnosed as one of the many common infectious diseases with overlapping symptoms. Thus, it is recommended that HIV be considered in people presenting an unexplained fever who may have risk factors for the infection.[28]
