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 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.
At least once a week, I am asked by one of my HIV-infected patients whether they need to continue to practice safe sex if they are in a monogamous (one mate only) relationship with an HIV-infected partner. Put another way, since both partners already have HIV, what’s the harm of unprotected sex? Actually, this is not an easy question to answer fully.

Changes in survival of people infected with HIV. As therapies have become more aggressive, they have been more effective, although survival with HIV infection is not yet equivalent to that in uninfected people. Modified from an original published by Lohse et al (2007), “Survival of persons with and without HIV infection in Denmark, 1995-2005.”
There is less information on the effectiveness of PEP for people exposed via sexual activity or intravenous drug use — however, if you believe you have been exposed, you should discuss the possibility with a knowledgeable specialist (check local AIDS organizations for the latest information) as soon as possible. All rape victims should be offered PEP and should consider its potential risks and benefits in their particular case.

Consistent condom use reduces the risk of HIV transmission by approximately 80% over the long term. When condoms are used consistently by a couple in which one person is infected, the rate of HIV infection is less than 1% per year. There is some evidence to suggest that female condoms may provide an equivalent level of protection. Application of a vaginal gel containing tenofovir (a reverse transcriptase inhibitor) immediately before sex seems to reduce infection rates by approximately 40% among African women. By contrast, use of the spermicide nonoxynol-9 may increase the risk of transmission due to its tendency to cause vaginal and rectal irritation.

Medications that fight HIV are called antiretroviral medications. Different antiretroviral medications target the virus in different ways. When used in combination with each other, they are very effective at suppressing the virus. It is important to note that there is no cure for HIV. ART only suppresses reproduction of the virus and stops or delays the disease from progressing to AIDS. Most guidelines currently recommend that all HIV-infected people who are willing to take medications should have them initiated shortly after being diagnosed with the infection. This delays or prevents disease progression, improves overall health of an infected person, and makes it less likely that they will transmit the virus to their partners.
AIDS is usually marked by a very low number of CD4+ lymphocytes, followed by a rise in the frequency of opportunistic infections and cancers. Doctors monitor the number and proportion of CD4+ lymphocytes in the patient’s blood in order to assess the progression of the disease and the effectiveness of different medications. About 10% of infected individuals never progress to this overt stage of the disease.
Fixing HIV spending: leading AIDS advocates agree that a doubling of federal funding could make a dramatic difference in the fight against the disease, though they diverge when asked how they would allocate the additional money
In the developed world, antiretroviral therapy has greatly improved prognosis and increased survival rates. Public education programs have raised awareness such that testing and prevention of infection are more common. Both of these approaches are difficult in countries with undereducated or underfunded populations.
The most common route of infection varies from country to country and even among cities, reflecting the population in which HIV was introduced initially and local practices. Co-infection with other viruses that share similar routes of transmission, such as hepatitis B, hepatitis C, and human herpes virus 8 (HHV8; also known as Kaposi sarcoma herpes virus [KSHV]), is common.

Another sign of late HIV infection are nail changes, such as clubbing (thickening and curving of the nails), splitting of the nails, or discoloration (black or brown lines going either vertically or horizontally).
AIDS is an advanced stage of HIV infection. Because the CD4 cells in the immune system have been largely destroyed, people with AIDS often develop symptoms and signs of unusual infections or cancers. When a person with HIV infection gets one of these infections or cancers, it is referred to as an “AIDS-defining condition.” Examples of AIDS-defining conditions are listed in Table 1. Significant, unexplained weight loss also is an AIDS-defining condition. Because common conditions like cancer or other viral conditions like infectious mononucleosis also can cause weight loss and fatigue, it is sometimes easy for a physician to overlook the possibility of HIV/AIDS. It is possible for people without AIDS to get some of these conditions, especially the more common infections like tuberculosis.
Sexual contact. People at greatest risk are those who do not practice safer sex by always using a condom, those who have multiple sexual partners, those who participate in anal intercourse, and those who have sex with a partner who has HIV infection and/or other sexually transmitted diseases (STDs). In the United States and Europe, most cases of sexually transmitted HIV infection result from homosexual contact, whereas in Africa, the disease is spread primarily through sexual intercourse among heterosexuals. Most people with AIDS in the United States are between 25 and 44 years of age.
The presentation of HIV depends on the stage of the disease that the patient is in. In the early stages of the disease there may be few or no (mild) infections, while in the later stages there may be more severe infections and even some forms of cancer.
HIV disease becomes AIDS when your immune system is seriously damaged. If you have less than 200 CD4 cells or if your CD4 percentage is less than 14%, you have AIDS. See Fact Sheet 124 for more information on CD4 cells. If you get an opportunistic infection, you have AIDS. There is an “official” list of these opportunistic infections put out by the Centers for Disease Control (CDC). The most common ones are:

General Health – it is crucial to take medication correctly and take steps to avoid illness. People living with HIV should seek to improve their general health by regularly exercising, eating healthfully, and not smoking.
Infected mothers should not breastfeed if they live in countries where formula feeding is safe and affordable. However, in countries where infectious diseases and undernutrition are common causes of infant death and where safe, affordable infant formula is not available, the World Health Organization recommends that mothers breastfeed. In such cases, the protection provided by breastfeeding from potentially fatal infections may counterbalance the risk of HIV transmission.
Both HIV-1 and HIV-2 are believed to have originated in non-human primates in West-central Africa, and are believed to have transferred to humans (a process known as zoonosis) in the early 20th century.
Because host cells do not have the ability to replicate “viral RNA” but are able to transcribe messenger RNA, RNA viruses must contain enzymes to produce genetic material for new virions. For certain viruses the RNA is replicated by a viral enzyme (transcriptase) contained in the virion, or produced by the host cell using the viral RNA as a messenger. In other viruses a reverse transcriptase contained in the virion transcribes the genetic message on the viral RNA into DNA, which is then replicated by the host cell. Reverse transcriptase is actually a combination of two enzymes: a polymerase that assembles the new DNA copy and an RNase that degrades the source RNA.
HIV symptoms (which often appear many times months after the infection) are similar to flu symptoms, and may disappear after some time. HIV may remain dormant and asymptomatic for years until it surfaces suddenly. A common first symptom of HIV is enlarged lymph nodes for three months or more. This may be accompanied by weight loss, yeast infections, memory loss, skin rashes, etc. According to the Center for Disease Control and prevention (CDC)in the United States, AIDS is the advanced stage of the HIV infection in which a person has less than 200 T4 immune cells per cubic millimetre of blood.
The second role of the federal government is largely symbolic but no less controversial. 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. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
