AIDS is an infectious disorder that suppresses the normal function of the immune system. It is caused by the human immunodeficiency virus (HIV), which destroys the body’s ability to fight infections. Specific cells of the immune system that are responsible for the proper response to infections (T cells) are destroyed by this virus. Characteristically a person infected with HIV initially experiences no symptoms for a variable period of time. This may be followed by the development of persistent generalized swelling of the lymph nodes (AIDS-related lymphadenopathy). Eventually most patients infected with HIV experience a syndrome of symptoms that includes excessive fatigue, weight loss, and/or skin rashes.

In IRIS, symptoms of various infections worsen or appear for the first time because immune responses improve (are reconstituted), increasing inflammation at sites of infection. Symptoms sometimes worsen because parts of dead viruses persist, triggering immune responses.

Exposure to HIV does not always lead to infection, and some people who have had repeated exposures over many years remain uninfected. Moreover, many HIV-infected people remain well for more than a decade. A very few HIV-infected, untreated people have remained well for over 20 years. Why some people become ill so much sooner than others is not fully understood, but a number of genetic factors appear to influence both susceptibility to infection and progression to AIDS after infection.
By 30 June 2006, 25,703 people in Australia were infected with HIV, 9,827 had AIDS and 6,621 died as a result of HIV/AIDS. NSW had the highest number of deaths, followed by Vic, QLD, WA, SA, ACT, NT and TAS.

HIV is carried in semen (cum), vaginal fluids, blood, and breast milk. The virus gets in your body through cuts or sores in your skin, and through mucous membranes (like the inside of the vagina, rectum, and opening of the penis). You can get HIV from:
The main treatment for HIV is antiretroviral therapy (ART), a combination of daily medications that stop the virus from reproducing. This helps protect your CD4 cells, keeping your immune system strong enough to fight off disease.

A thorough discussion of the history of AIDS and the biologic link between HIV and AIDS can be found in an article entitled ” The relationship between the human immunodeficiency virus and the acquired immunodeficiency syndrome ” at the National Institute of Allergy and Infectious Diseases Web site. The document was originally written in September 1995, prior to the advent of highly active antiretroviral therapy (HAART), which has significantly improved AIDS-free survival in persons infected with HIV. This version was updated March 2010.
Other potential exposures include vaginal and anal sexual intercourse and sharing needles during intravenous drug use. There is less evidence for the role of antiretroviral postexposure prophylaxis after these exposures. In part, this is because the HIV status of a sexual partner or drug user is not usually known by the exposed person. Nevertheless, the U.S. Centers for Disease Control and Prevention (CDC) recommends treatment for people exposed through sexual activity or injectable drug use to someone who is known to carry HIV. If the HIV status of the source is not known, the decision to treat is individualized. Concerned people should see their physician for advice. If a decision to treat is made, medications should be started within 72 hours of the exposure.
When HIV grows (that is, by reproducing itself), it acquires the ability to change (mutate) its own structure. These mutations enable the virus to become resistant to previously effective drug therapy.
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 morbidity or reduction in mortality is not consistent.
Transgender people have also been hit especially hard by the epidemic despite comprising a similarly small percentage of the U.S. population. While better data is needed to understand the full impact of HIV on the transgender community, one international analysis found that transgender women in certain communities have 49 times the odds of living with HIV than the general population. Although HIV prevalence among transgender men is relatively low (0-3%) according to the CDC, some data suggest transgender men may still yet be at elevated risk for HIV acquisition.

And having herpes can also be a risk factor for contracting HIV. This is because genital herpes can cause ulcers that make it easier for HIV to enter the body during sex. And people who have HIV tend to have more severe herpes outbreaks more often because HIV weakens the immune system.
UNAIDS announced that 18.2 million people were on ART, including 910 000 children, double the number five years earlier. However, achieving increased ART access means a greater risk of drug resistance and the WHO released a report on dealing with this growing issue.99

For HIV treatment to be effective in reducing HIV incidence, infections need to be diagnosed as quickly as possible. This requires increasing HIV testing coverage and frequency. CDC recommends testing all persons aged 13–64 years at least once as a routine part of medical care and more frequent testing (at least annually) for persons at high risk for HIV infection (7). A large proportion (84%) of HIV sexually transmitted from MSM and heterosexual persons is transmitted by MSM (1). Some sexually active MSM might benefit from more frequent testing (e.g., every 3 to 6 months) (18). Testing according to CDC guidelines is critical to diagnosing HIV infection, so that anyone who receives a diagnosis of HIV infection can start antiretroviral treatment. Overall, prior year testing increased among groups at high risk over time. However, 29% of MSM (in 2014), 42% of persons who inject drugs (in 2015), and 59% of heterosexual persons at increased risk (in 2016) did not report testing in the past 12 months. In addition, it is important to note that these data are from persons residing in large metropolitan statistical areas in the United States. Studies have found that persons residing in rural areas are less likely to report prior HIV testing, including in the past 12 months, compared with their urban counterparts, and that persons living in rural areas are more likely to have HIV infection diagnosed at a late stage (19,20). Barriers to implementing routine testing include lack of time, competing priorities, and concerns about reimbursement on the health care provider’s part and stigma and lack of perceived risk on the client’s part (21). Lack of perceived risk was also one of the main reasons cited by MSM in NHBS for not testing in the past 12 months.
Dr. Michael Gottlieb, the lead author of the report and a renowned physician specializing in H.I.V./AIDS, treated Rock Hudson before he died of AIDS complications in 1985 and still practices in Los Angeles. Gottlieb said he is often asked why he didn’t include in that first report the documented case of the gay African-American man, who had both PCP and cytomegalovirus, a virus that attacks the organs of patients with compromised immune systems. He explains that he discovered the case after the report was finalized. “Until recently, I wouldn’t have thought it mattered,” said Gottlieb, who said that he and others on the front line were grappling with an unprecedented and frightening medical mystery and largely working in the dark. “But in retrospect, I think it might’ve made a difference among gay black men.”
Developing AIDS requires that the person acquire HIV infection. Risks for acquiring HIV infection include behaviors that result in contact with infected blood or sexual secretions, which pose the main risk of HIV transmission. These behaviors include sexual intercourse and injection drug use. The presence of sores in the genital area, like those caused by herpes, makes it easier for the virus to pass from person to person during intercourse. HIV also has been spread to health care workers through accidental sticks with needles contaminated with blood from HIV-infected people, or when broken skin has come into contact with infected blood or secretions. Blood products used for transfusions or injections also may spread infection, although this has become extremely rare (less than one in 2 million transfusions in the U.S.) due to testing of blood donors and blood supplies for HIV. Finally, infants may acquire HIV from an infected mother either while they are in the womb, during birth, or by breastfeeding after birth.
In 2016 about 36.7 million people were living with HIV and it resulted in 1 million deaths. There were 300,000 fewer new HIV cases in 2016 than in 2015. Most of those infected live in sub-Saharan Africa. Between its discovery and 2014 AIDS has caused an estimated 39 million deaths worldwide. HIV/AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading. HIV is believed to have originated in west-central Africa during the late 19th or early 20th century. AIDS was first recognized by the United States Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade.
Most individuals infected with HIV will progress to AIDS, if not treated. However, there is a tiny group of patients who develop AIDS very slowly or never at all. These patients are called non-progressors and many seem to have a genetic difference which prevents the virus from attaching to certain immune receptors.

In Seattle, a group headed by Hans-Peter Kiem and Keith Jerome is taking a more futuristic approach. Using an enzyme called Zinc Finger Nuclease, they are genetically altering blood and marrow stem cells so as to disable CCR5, the doorway for infection in T cells. Researchers will modify the stem cells outside the body, so that when the cells are returned some portion of the T cells in the bloodstream will be resistant to H.I.V. infection. Over time, they hope, those cells will propagate, and the patient will slowly build an immune system that is resistant to the virus. Those patients might still have a small reservoir of H.I.V., but their bodies would be able to regulate the infection.
Sex is an old battleground in public education. Liberals and conservatives argued over it in the decade following the sexual revolution of the 1960s, initially over whether sexual issues should be discussed in schools. After all, earlier generations who went to public schools learned mainly about reproductive organs. As new classes began appearing in the late 1970s, children learned about the sexual choices people make. If liberals appeared to win the “sex ed.” debate, growing social problems helped: rises in teen pregnancies and sexually transmitted diseases secured a place for more explicit school health classes. The much greater threat of AIDS pushed state legislatures into action. By the mid-1990s, AIDS prevention classes had been mandated in at least 34 states and recommended in 14. But the appearance of even more explicit teaching has reinvigorated the sex ed. debate.

Antiviral treatment options have primarily included combinations of two NRTIs, often referred to as “nucs,” and a third drug, typically being a boosted PI, a NNRTI, often called “non-nucs, and InSTIs such as RAL, EVG or dolutegravir (Tivicay, DTG). Many of these drugs are available in fixed-dose combinations as well as increasing numbers of drugs as single-tablet regimens.
