Some conspiracy theories have been put about. Operation INFEKTION was a worldwide Soviet active measures operation to spread the claim that the United States had created HIV/AIDS. Surveys show that a significant number of people believed – and continue to believe – in such claims.
ABSTRACT Human immunodeficiency virus type 1 (HIV-1) Env-, Gag-, Pol-, Nef-, and Tat-specific cytotoxic T-lymphocyte (CTL) activities were quantitated temporally in five patients with symptomatic primary HIV-1 infection. A dominant CD8 (+)-mediated, major
HIV treatments (antiretrovirals) are available and all people with HIV infection in Australia have access to this treatment. Available HIV treatments have dramatically improved the outlook for people with HIV.
AIDS is the more advanced stage of HIV infection. When the immune system CD4 cells drop to a very low level, a person’s ability to fight infection is lost. In addition, there are several conditions that occur in people with HIV infection with this degree of immune system failure — these are called AIDS-defining illnesses.
In 1985, a blood test became available that measures antibodies to HIV that are the body’s immune response to the HIV. The test that for decades had been most commonly used for diagnosing infection with HIV was referred to as an ELISA. If the ELISA found HIV antibodies, the results needed to be confirmed, typically by a test called a Western blot. Recently, tests have become available to look for these same antibodies in saliva, some providing results within one to 20 minutes of testing. As a result, the FDA has approved home HIV antibody testing that is self-administered using saliva. Antibodies to HIV typically develop within several weeks of infection. During this interval, patients have virus in their body but will test negative by the standard antibody test, the so-called “window period.” In this setting, the diagnosis can be made if a test is used that actually detects the presence of virus in the blood rather than the antibodies, such as tests for HIV RNA or p24 antigen. A relatively new test has been approved that measures both HIV antibodies and p24 antigen, shrinking the duration of the window period from infection to diagnosis. New federal guidelines now recommend that HIV screening tests be performed with these assays and, if they are positive, that a confirmatory antibody test be performed that will determine if the patient has HIV-1, the most common form of HIV circulating around the world, or HIV-2, a related virus that occurs most frequently in Western Africa. If the confirmatory antibody test is negative, then there remains the possibility that the original test detected viral p24 antigen and not antibodies. Therefore, the recommendations are that if the confirmatory antibody test is negative a test for HIV RNA, a test for the presence of virus be performed. If the antibody is negative and the viral test is positive, the patient is diagnosed with acute or primary HIV infection and will develop a positive antibody test over the ensuing weeks.
Antiviral medications are associated with adverse effects and thus contribute to patient morbidity and mortality rates, especially because of the growing population of long-term survivors who are receiving combination antiviral therapy. In particular, protease inhibitors may cause lipid-profile abnormalities.
The sexual practices with the highest risks are those that cause mucosal trauma, typically intercourse. Anal-receptive intercourse poses the highest risk. Mucous membrane inflammation facilitates HIV transmission; sexually transmitted diseases, such as gonorrhea, chlamydial infection, trichomoniasis, and especially those that cause ulceration (eg, chancroid, herpes, syphilis), increase the risk severalfold. Other practices that cause mucosal trauma include fisting (inserting most or all of the hand into the rectum or vagina) and using sexual toys. When used during intercourse with an HIV-infected partner and/or with multiple concurrent sex partners, these practices increase the risk of HIV transmission.

He introduced me to one of his patients, whom I’ll call Gordon. A tall, genial man with rimless glasses stood up to shake my hand, and I saw that he had the signature protruding belly. He has been H.I.V.-positive for almost forty years, and he said he felt lucky to be alive: “A ten-year partner of mine who had the same strain of H.I.V., who ate the same food, had the same doctors, took the same early H.I.V. meds, died in June, 1990, almost twenty-five years ago.”
Many drugs have become available to fight both the HIV infection and its associated infections and cancers. These drugs have been called highly active antiretroviral therapy (HAART). More commonly, they are simply referred to as ART. Although these medications do not cure HIV/AIDS, ART has greatly reduced HIV-related complications and deaths.
The one way in which we know we can protect against infection with HIV is by avoiding contact with body fluids, such as semen, blood, blood products, or milk from people who are infected. Indeed, it has been demonstrated repeatedly that this precaution, simple enough in the developed world, is sufficient to prevent infection, as health-care workers can take care of AIDS patients for long periods without seroconversion or signs of infection.
Frightened and overwhelmed, he eventually landed on the doorstep of Grace House. “I couldn’t believe I was living in a shelter,” said Huff, who is now couch-surfing, applying for jobs at fast-food outlets and retail shops and attending Sturdevant’s support group, determined to stay healthy. “I felt like I had no one. Off and on, I got tired of living, because all I was doing was basically dying trying to stay alive.”
Although the American research Robert Gallo at the National Institutes of Health (NIH) believed he was the first to find HIV, it is now generally accepted that the French physician Luc Montagnier (1932-) and his team at the Pasteur Institute discovered HIV in 1983-84.
Infections in women have dropped 40% since 2005 in the U.S., and new HIV infections in U.S. children have fallen dramatically. This is largely a result of testing and treating infected mothers, as well as establishing uniform testing guidelines for blood products.
Counseling for parenteral drug users: Counseling about the risk of sharing needles is important but is probably more effective if combined with provision of sterile needles, treatment of drug dependence, and rehabilitation.
A failure to inform in AIDS cases has given rise to both civil and criminal lawsuits. One such case was brought by Mark Christian, the lover of actor Rock Hudson, against Hudson’s estate. Christian won his suit on the ground that Hudson concealed his condition and continued their relationship, and the jury returned a multimillion-dollar verdict despite the fact that there was no evidence that Christian had been infected. Another case was brought in Oregon in 1991, when criminal charges were filed against Alberto Gonzalez for knowingly spreading HIV by having sex with his girlfriend. After Gonzalez pleaded no contest to third-degree assault (a felony) and to two charges of recklessly endangering others, he received an unusual sentence: the court ordered him to abstain from sex for five years and placed him under house arrest for six months. Although such convictions are increasingly common, courts have also recognized that not knowing one has HIV can be a valid defense. In C. A. U. v. R. L., 438 N.W.2d 441 (1989), for example, the Minnesota Court of Appeals affirmed a trial court’s finding that the plaintiff could not recover damages from her former fiancé, who had unknowingly given her the virus.
During this time, many scientists, researchers and government administrators were afraid to speak openly about condoms, needle exchange and L.G.B.T. issues for fear of reprisal and loss of funding. Community organizations became targets of anti-gay crusades, subjected to intense scrutiny, including exhaustive audits, by federal agencies. “It is no coincidence that new rates of H.I.V. infection among gay men, especially gay black men, began to spike sharply from 2000 on, because of an anti-science campaign that allowed for little or nothing to be done for a maligned community simply due to ideology and bigotry,” Millett said. “The hostile environment made funding effective H.I.V.-prevention programs, messages or research impossible for U.S. communities most impacted by H.I.V.”

In September, the WHO launched new treatment guidelines recommending that all people living with HIV should receive antiretroviral treatment, regardless of their CD4 count, and as soon as possible after their diagnosis.96
Also in July, South Africa’s Constitutional Court orders the government to make the HIV drug nevirapine available to all HIV-positive pregnant women and their newborn children following a legal challenge by the Treatment Action Campaign. 77
In the United States, HIV is spread mainly by having sex with or sharing drug injection equipment with someone who has HIV. To reduce your risk of HIV infection, use condoms correctly and consistently during sex, limit your number of sexual partners, and never share drug injection equipment.
Blood and genital secretions from people with HIV are considered infectious and the utmost care should be taken in handling them. Fluids that are contaminated with blood also are potentially infectious. Feces, nasal secretions, saliva, sputum, sweat, tears, urine, and vomit are not considered infectious unless visibly bloody.
Some people think that HIV is not the cause of AIDS. They dispute the connection between HIV and AIDS, the existence of HIV itself, or the validity of HIV testing and treatment methods. These claims, known as “AIDS denialism”, are rejected by the scientific community. However, they have had a significant impact, particularly in South Africa. There the government’s official embrace of AIDS denialism (1999–2005) was responsible for its weak response to that country’s AIDS epidemic. It has been blamed for hundreds of thousands of avoidable deaths and HIV infections.
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.”

The second problem is our uncertainty over what form protective immunity to HIV might take. It is not known whether antibodies, cytotoxic T lymphocyte responses, or both are necessary to achieve protective immunity, and which epitopes might provide the targets of protective immunity. Third, if strong cytotoxic responses are necessary to provide protection against HIV, these might be difficult develop and sustain through vaccination. Other effective viral vaccines rely on the use of live, attenuated viruses and there are concerns over the safety of pursuing this approach for HIV. Another possible approach is the use of DNA vaccination, a technique that we discuss in Section 14-25. Both of these approaches are being tested in animal models.
Some people may develop a flu-like illness within a month or two after exposure to the HIV virus, although many people do not develop any symptoms at all when they first become infected. Many people mistake this flu-like illness as being caused by something else. Persistent or severe symptoms may not surface for 10 years or more, after HIV first enters the body in adults, or within two years in children born with an HIV infection.
