All sexually active adults should know their HIV status and should be tested for HIV routinely at least once. This is the only way to know whether one is HIV infected. It is not unusual for a person to get HIV from a person they never knew could have HIV; again, most people with HIV do not know it for years. Testing is important yearly or more often if a person has risk factors for HIV. If someone has a history of engaging in unprotected sex outside of a mutually monogamous relationship (meaning both partners have sex only with each other) or sharing needles while using drugs, he or she should have an HIV test. Early testing, recognition of the signs and symptoms of HIV infection, and starting treatment for HIV as soon as possible can slow the growth of HIV, prevent AIDS, and decrease the risk of transmission to another person. If a woman is pregnant and infected with HIV, she can greatly reduce the risk to her unborn child by getting treatment. HIV testing is routinely offered at the first prenatal visit.
The infected person frequently gets infections and even some forms of cancer which a healthy immune system would have gotten rid of quite easily. These infections are known as opportunistic infections. HIV infection, once established, cannot be eliminated by the body or by drugs.

In the United States, guidelines for using antiviral therapy have been developed and are updated on a regular basis by an expert panel assembled by the DHHS, the IAS-USA panel, and others. The DHHS guidelines are available at https://aidsinfo.nih.gov/. The most recent IAS-USA guidelines were published in the Journal of the American Medical Association (JAMA) in the summer of 2016.
In June 1995, the FDA approved the first protease inhibitor beginning a new era of highly active antiretroviral treatment (HAART). Once incorporated into clinical practice HAART brought about an immediate decline of between 60% and 80% in rates of AIDS-related deaths and hospitalisation in those countries which could afford it.62
I am a Ghanaian Nurse. ActuaCly my research area was on Prevention of Mother to child Transmission of HIV. I have also had the opportunity of working for an NGO-Projects Abroad Ghana, educating schools and orphanages on HIV/AIDS.
HIV/AIDS; MMWR, June 5, 1981The June 5, 1981, edition of MMWR (Morbidity and Mortality Weekly Report), published by the U.S. Centers for Disease Control and Prevention, described a rare lung infection, known as Pneumocystis carinii pneumonia, in five homosexual men in Los Angeles. The infections were later linked to AIDS.CDC
The idea of combining medications into a “cocktail” came in the mid-nineteen-nineties, mirroring the way oncologists treated cancer. Cancer cells, like H.I.V. particles, can mutate quickly enough to escape a single targeted drug. The treatment regimen—HAART, for highly active antiretroviral therapy—was put through clinical trials by prominent researchers such as David Ho, of the Aaron Diamond Institute, in New York. I gave the cocktail to one of my patients, David Sanford, and less than a month after beginning treatment his fever fell, his infections disappeared, his energy returned, and he started to gain weight. The H.I.V. in his bloodstream plummeted to an undetectable level, where it has remained. Later, in a Pulitzer Prize-winning article, Sanford wrote, “I am probably more likely to be hit by a truck than to die of AIDS.” That now holds true for a great majority of people with H.I.V. in the United States. In the past five years, not one of the dozens of H.I.V. patients I’ve cared for has died of the disease.
In June 1982, a group of cases among gay men in Southern California suggested that the cause of the immune deficiency was sexual and the syndrome was initially called gay-related immune deficiency (or GRID).6

Choice of initial and/or second-line therapy for HIV-2 has not yet been defined. HIV-2 appears to be resistant to NNRTIs intrinsically, but may be sensitive to NRTIs, though the mechanism is poorly understood. Protease inhibitors have shown variable effect, while integrase inhibitors are also being evaluated. Combination regimens of the above listed therapies are being looked into as well, also showing variable effect depending on the types of therapies combined. While the mechanisms are not clearly understood for HIV-1 and HIV-2, it is known that they use different pathways and patterns, making the algorithms used to evaluate HIV-1 resistance-associated mutations irrelevant to HIV-2.

Cellular immune response to HIV. The cellular immune response is induced upon the entry of HIV into the target cells (e.g., T cells) and synthesis of viral proteins (Figure 1). MHC class I on the cell surface displays the intracellularly degraded HIV peptide fragments for recognition by T-cell receptors (TCR) on CD8+ T cells (Figure 3). CD8+ T cells lyse HIV infected cells and secrete cytokines, i.e. interferon-γ (IFN-γ), tumor necrosis factor α (TNF-α), and chemokines, i.e. MIP-1 α, MIP β and RANTES, that inhibit virus replication and block viral entry into CD4+ T cells. Development of CD8+ T cells is crucial for control of HIV replication. This results in declining viraemia after primary infection. In the early stages of infection, CD4+ T cells lose their proliferative capacity and therefore their contribution to viral control is minor. However, during chronic infection CD4+T cells are present and secrete interleukin-2 (IL-2) or cytokines, such as IFN-γ, to control viraemia.
The most common side effect associated with NNRTIs is a rash, typically occurring during the first weeks of therapy. This is most common in individuals treated with NVP. In this case, the overall risk of rash is reduced if therapy is started as a single 200 mg NVP pill once per day during the first two weeks before increasing to the full dose of 200 mg twice per day. If the rash is mild, therapy usually can be continued if antihistamines are given, and if the rash resolves, treatment with the NNRTI can be continued. If the rash is severe, associated with liver inflammation or blisters, changes in the mouth or around the eyes, or with high fevers, therapy with the NNRTI usually needs to be discontinued. Decisions regarding continuing or stopping treatment need to be made with the primary care professional. In some patients, NVP can cause a severe allergic reaction characterized by fever, rash, and severe liver inflammation. Recent data suggests that the groups at the greatest risk for the severe reaction are those with stronger immune systems, such as HIV-uninfected people given this treatment after an exposure to HIV, women with CD4+ T cells >250 cells per mm3, and men with CD4+ T cells >400 cells per mm3. There is also likely to be increased risk in pregnant women and individuals with other underlying liver diseases. Consequently, NVP probably should not be used in any of these groups, or if used, used with caution. In addition, whenever NVP is started, liver tests that are markers for liver inflammation should be monitored at regular intervals during the first several months of treatment.

Though there are two cases of people who have been cured, there is currently no safe cure for HIV (see fact sheet 485.) There is no way to “clear” HIV from the body. Antiretroviral therapy (ART, see fact sheet 403) can prevent or reverse the damage to your immune system. Most people stay healthy if they stay adherent to ART.
One of the proteins that enters the cell with the viral genome is the viral reverse transcriptase, which transcribes the viral RNA into a complementary DNA (cDNA) copy. The viral cDNA is then integrated into the host cell genome by the viral integrase, which also enters the cell with the viral RNA. The integrated cDNA copy is known as the provirus. The infectious cycle up to the integration of the provirus is shown in Fig. 11.23. In activated CD4 T cells, virus replication is initiated by transcription of the provirus, as we will see in the next section. However, HIV can, like other retroviruses, establish a latent infection in which the provirus remains quiescent. This seems to occur in memory CD4 T cells and in dormant macrophages, and these cells are thought to be an important reservoir of infection.

This expensive test isn’t used for general screening. It’s for people who have early symptoms of HIV or recently had a high-risk exposure. This test doesn’t look for antibodies, but for the virus itself. It takes from seven to 28 days for HIV to be detectable in the blood. This test is usually accompanied by an antibody test.

Correct and consistent use of male and female condoms during vaginal or anal penetration can protect against the spread of sexually transmitted infections, including HIV. Evidence shows that male latex condoms have an 85% or greater protective effect against HIV and other sexually transmitted infections (STIs).

HIV can be suppressed by combination ART consisting of 3 or more ARV drugs. ART does not cure HIV infection but suppresses viral replication within a person’s body and allows an individual’s immune system to strengthen and regain the capacity to fight off infections.
In 2011, HPTN 052, a study of 1,763 couples in 13 cities on four continents funded by the National Institute of Allergy and Infectious Diseases, found that people infected with H.I.V. are far less likely to infect their sexual partners when put on treatment immediately instead of waiting until their immune systems begin to fall apart. This “test and treat” strategy also significantly reduces the risk of illness and death. The data was so persuasive that the federal government began pushing new H.I.V./AIDS treatment guidelines to health care providers the following year. And in 2012, the Food and Drug Administration approved the preventive use of Truvada, in the form of a daily pill to be taken as pre-exposure prophylaxis (commonly called PrEP). It has been found to be up to 99 percent effective in preventing people who have not been infected with H.I.V. from contracting the virus, based on the results of two large clinical trials; an estimated 80,000 patients have filled prescriptions over the past four years.
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.
Condomless sex – having sex without a condom can put a person at risk of contracting HIV and other sexually transmitted infections (STIs). HIV can be transmitted by having sex without a condom (vaginal, oral, and/or anal sex). It can also be transmitted by sharing sex toys with someone infected with HIV. Condoms should be used with every sexual act.
AIDS stigma exists around the world in a variety of ways, including ostracism, rejection, discrimination and avoidance of HIV infected people; compulsory HIV testing without prior consent or protection of confidentiality; violence against HIV infected individuals or people who are perceived to be infected with HIV; and the quarantine of HIV infected individuals. Stigma-related violence or the fear of violence prevents many people from seeking HIV testing, returning for their results, or securing treatment, possibly turning what could be a manageable chronic illness into a death sentence and perpetuating the spread of HIV.
