simian-human immunodeficiency virus a chimeric, engineered virus with the envelope of human immunodeficiency virus and the cytoplasm and nucleus of simian immunodeficiency virus; it is used in animal models because it is a better mimic of HIV than SIV is.

Sexually transmitted diseases, or STDs, are infections that are transmitted during any type of sexual exposure, including intercourse (vaginal or anal), oral sex, and the sharing of sexual devices, such as vibrators. Women can contract all of the STDs, but may have no symptoms, or have different symptoms than men do. Common STDs in women are:

Needles. HIV is frequently spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa, through accidental sticks with contaminated needles or other medical instruments, is rare.

It is important to note that although HIV is highly virulent, transmission is greatly reduced when an HIV-infected person has a suppressed or undetectable viral load (<50 copies/ml) due to prolonged and successful anti-retroviral treatment. Hence, it can be said to be almost impossible (but still non-zero) for an HIV-infected person who has an undetectable viral load to transmit the virus, even during unprotected sexual intercourse, as there would be a negligible amount of HIV present in the seminal fluid, vaginal secretions or blood, for transmission to occur.[116][117] This does not mean however, that prolonged anti-retroviral treatment will result in a suppressed viral load. An undetectable viral load, generally agreed as less than 50 copies per milliliter of blood, can only be proven by a polymerase chain reaction (PCR) test.[118] Jump up ^ Templeton, DJ; Millett, GA; Grulich, AE (February 2010).

It is to guide school efforts through advice, sponsorship, and public speeches, and primarily involves the offices of the surgeon general and of the federal AIDS policy coordinator. Koop, who was a Reagan appointee, roused a fair degree of controversy, yet it was nothing compared to the upheaval that greeted statements by appointees of the Clinton administration. AIDS policy czar Kristine Gebbie and surgeon general M. Joycelyn Elders were forced from their posts after making statements that conservatives found appalling—Gebbie promoting attitudes toward pleasurable sex and Elders indicating a willingness to have schools talk about masturbation. Thereafter, the administration frequently stressed abstinence as its top priority for school AIDS programs. Patients with late-stage AIDS may develop Kaposi's sarcoma (KS), a skin tumor that primarily affects homosexual men. KS is the most common AIDS-related malignancy. It is characterized by reddish-purple blotches or patches (brownish in people with dark skin) on the skin or in the mouth. About 40% of patients with KS develop symptoms in the digestive tract or lungs. KS may be caused by a herpes virus-like sexually transmitted disease agent rather than HIV. A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that. In patients with HIV infection, certain syndromes are common and may require different considerations (see Table: Common Manifestations of HIV Infection by Organ System). Some patients present with cancers (eg, Kaposi sarcoma, B-cell lymphomas) that occur more frequently, are unusually severe, or have unique features in patients with HIV infection (see Cancers Common in HIV-Infected Patients). In other patients, neurologic dysfunction may occur. The term viral tropism refers to the cell types a virus infects. HIV can infect a variety of immune cells such as CD4+ T cells, macrophages, and microglial cells. HIV-1 entry to macrophages and CD4+ T cells is mediated through interaction of the virion envelope glycoproteins (gp120) with the CD4 molecule on the target cells' membrane and also with chemokine co-receptors.[22][40] Because HIV infection produces a wide range of symptoms, the CDC has compiled a list of conditions regarded as defining AIDS. The physician will use the CDC list to decide whether the patient falls into one of these three groups: The primary mechanism for immunologic control of HIV appears to be CD8+ cytotoxic T-cells. T-cell responses are correlated with the steady-state viral load and hence, the rate of progression. [63] Cellular immunity is apparently responsible for some multiply-exposed, but uninfected individuals. [64, 65] HIV infection can cause AIDS to develop. However, it is possible to contract HIV without developing AIDS. Without treatment, HIV can progress and, eventually, it will develop into AIDS in the vast majority of cases. Another way to diagnose HIV infection is to do a special test to detect viral particles in the blood. These tests detect RNA, DNA, or viral antigens. However, these tests are more commonly used for guiding treatment rather than for diagnosis. The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which can infect humans when it comes in contact with tissues that line the vagina, anal area, mouth, or eyes, or through a break in the skin. HIV is treated with antiretrovirals (ARVs). The treatment fights the HIV infection and slows down the spread of the virus in the body. Generally, people living with HIV take a combination of medications called HAART (highly active antiretroviral therapy) or cART (combination antiretroviral therapy). ¶ Data include all participants with complete, valid survey data from 17 cities who reported male or female gender, who ever had sex with a member of the opposite sex, never injected drugs, and who had negative HIV test results. Talk to your sexual partner(s). Get tested for other sexually transmitted diseases (STDs), and use protection every time you have sex. Talk to your doctor about pre-exposure prophylaxis (PrEP). When used consistently, this daily medication can lower the chances of transmission. 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-1 originated in Central Africa in the first half of the 20th century, when a closely related chimpanzee virus first infected humans. Epidemic global spread began in the late 1970s, and AIDS was recognized in 1981. ^ Jump up to: a b Pope M, Haase AT (2003).

In January 1995, the settlement in a lawsuit brought by a Philadelphia construction worker with AIDS illustrated that the ADA could be used to fight caps on coverage. In 1992, the joint union-management fund for the Laborers' District Council placed a $10,000 limit on AIDS benefits, in stark contrast to the $100,000 allowed for other catastrophic illnesses. At that time, the fund said the cap on AIDS benefits was designed to curb all health costs. In 1993, the EEOC ruled that the fund violated the ADA, and, backed by the AIDS Law Project of Philadelphia, the worker sued. Rather than fight an expensive lawsuit, the insurance fund settled: under the agreement, it extended coverage for all catastrophic illnesses to $100,000. Hailing the settlement as a major blow against widespread discrimination in insurance coverage, the law project's executive director, Nan Feyler, told the Philadelphia Inquirer, "You can't single out someone based on a stereotype."

These drugs, also referred to as "nukes," interfere with HIV as it tries to replicate and make more copies of itself. NRTIs include abacavir (Ziagen), lamivudine/zidovudine (Combivir), and emtricitabine (Emtriva) The time from HIV infection to the development of AIDS varies. Rarely, some individuals develop complications of HIV that define AIDS within one year, while others remain completely asymptomatic after as many as 20 years from the time of infection. However, in the absence of antiretroviral therapy, the time for progression from initial infection to AIDS is approximately eight to 10 years. The reason why people experience clinical progression of HIV at different rates remains an area of active research. In August, Janet and Robert Siliciano wrote about the Brigham men and the Mississippi baby in Science, saying that the cases confirmed that researchers were on the right path in attacking latent infection. The Berlin patient was an even more compelling example. Karl Salzwedel, the chief of Pathogenesis and Basic Research in the Division of aids at the National Institute of Allergy and Infectious Diseases, told me that until Timothy Brown “it wasn’t really clear how we would go about getting rid of the last bits of virus that remain in the reservoir.” Brown’s case provided “a proof of concept: it may be possible to eradicate latent H.I.V. from the body. It may be from a very risky and toxic method, but it’s proof of concept nonetheless.” Opportunistic infections may be caused by bacteria, viruses, fungi, and parasites that are normally controlled by the immune system.[35] Which infections occur depends partly on what organisms are common in the environment.[28] These infections may affect nearly every organ system.[36] Lyell's syndrome drug-induced, acute skin sensitivity reaction; characterized by acute erythema, urticaria, vasculitis, purpura, marked exfoliation (peeling), flaccid bullae formation, subepidermal separation/detachment Cushing's syndrome raised blood cortisol (e.g. due to pituitary tumour; long-term steroid therapy); characterized by central obesity, moon-like facies, acne, skin striae, hypertension, decreased carbohydrate tolerance and tendency to diabetes, female amenorrhoea and hirsutism In terms of symptoms, children are less likely than adults to have an early acute syndrome. They are, however, likely to have delayed growth, a history of frequent illness, recurrent ear infections, a low white blood cell count, failure to gain weight, and unexplained fevers. Children with AIDS are more likely to develop bacterial infections, inflammation of the lungs, and AIDS-related brain disorders than are HIV-positive adults. As a consequence of its high variability, HIV rapidly develops resistance to antiviral drugs. When antiviral drugs are administered, variants of the virus that carry mutations conferring resistance to their effects emerge and expand until former levels of plasma virus are regained. Resistance to some of the protease inhibitors appears after only a few days (Fig. 11.27). Resistance to some of the nucleoside analogues that are potent inhibitors of reverse transcriptase develops in a similarly short time. By contrast, resistance to the nucleoside zidovudine (AZT), the first drug to be widely used for treating AIDS, takes months to develop. This is not because AZT is a more powerful inhibitor, but because resistance to zidovudine requires three or four mutations in the viral reverse transcriptase, whereas a single mutation can confer resistance to the protease inhibitors and other reverse-transcriptase inhibitors. As a result of the relatively rapid appearance of resistance to all known anti-HIV drugs, successful drug treatment might depend on the development of a range of antiviral drugs that can be used in combination. It might also be important to treat early in the course of an infection, thereby reducing the chances that a variant virus has accumulated all the necessary mutations to resist the entire cocktail. Current treatments follow this strategy and use combinations of viral protease inhibitors together with nucleoside analogues (see Fig. 11.26).
