AIDS (acquired immune deficiency syndrome) is the final and one of the most serious stage of the infection by HIV, which produces severe damage to the immune system. AIDS begins when a person with infection by HIV has a count of cells CD4 (a type of immune cell also denominated ” T” cells; or “cooperating lymphocytes T”) below 200. Also it is defined by numerous opportunistic infections and cancers that appear in the presence of the infection by HIV. Causes, incidence and factors of risk AIDS ( acquired immune deficiency syndrome) is the fifth important cause of death in the people between 25 and 44 years of age in the

In the world, according to UNAIDS (United Nations on HIV / AIDS), the number of people infected by HIV is estimated at about 39 million in 2005, the majority living in developing countries. In 2005, 2.8 million people died because of AIDS and 4.1 million people were newly infected by the virus.
In developing countries, 6.8 million people infected by the virus need to be processed and only 24% of them have access to antiretroviral treatment, against 7% in 2003. Among the 800 000 children below 15 years infected by HIV in 2005, only 8 to 13% of them receive treatment. The covers anti-retroviral treatment vary according to regions of the globe: 75% of people infected and require treatment are actually treated in Latin America and the Caribbean, 23% in countries of Sub-Saharan Africa, 16% the countries of South Asia, East and South-East, 13% in the countries of Europe and Central Asia, 5% in the countries of North Africa and the Middle East.
In France, according to the latest report of Experts in June 2006 asked by the Ministry of Health, since the epidemic began around the 1980s until 30 June 2005 the number of AIDS cases is estimated at 60 and 212 26 239 are survivors.
Between 2003 and 2005, more than 12 655 notifications of HIV infection are reported (including approximately 9000 discovery of HIV. Sex is the main mode of contamination in 2004: 54% heterosexual, homosexual 24%, 11% of injecting drug users and is not known how contamination among others.
These are women of Saharan origin who are most frequently affected. Among heterosexual couples contamination occurs, most often while the couple is stable and that a partner does not know that he is HIV positive.
While the transmission of HIV as a result of injection drug used contaminated equipment is falling. In recent years, the frequency of HIV transmission among men who have sex with is worrying. The easing in homosexual behavior is a fact.
The diagnosis of AIDS disease is often asked when people do not know they were HIV positive and therapeutic care is so late, they are more often men who fall into this scenario. It goes without saying that prevention and health education among the general public are essential to imagine reversing the AIDS epidemic and reduce the number of people infected. The communication must not falter, it is essential to repeat tirelessly prevention messages and use of condoms in sexual relationships and to encourage screening. The education of adolescents must be done before the onset of sexual activity.
AIDS (Acquired Immune Deficiency Syndrome) is an infectious disease, viral chronic, characterized by declining defenses of the body. This leads to the emergence of opportunistic diseases, which are so called because they benefit from the progressive inability of a sick person to defend themselves in order to develop these opportunistic diseases are represented by certain infections or cancers, which will weaken further the agency reached.
What characterizes this infection is that it moves silently on a chronic: a person with HIV is not the disease AIDS immediately, it may take several years before the disease does occur.
Therefore, it is a sexually transmitted disease (STD). The only means of prevention is the protection of partners during sex with condoms when you do not know their HIV status and that of his partner, if condoms are not used, we talk about relative to risk.
A pregnant woman infected with HIV can transmit the virus to the child she is carrying. The transmission can be done by blood, mostly by sharing a syringe contaminated.
If a person has been infected by the AIDS virus, the virus is present in his body and will be HIV-positive vis-à-vis the virus, ie it has produced antibodies against the virus, HIV.
As long as a body has not been in contact with the AIDS virus, it will be HIV-negative.

This leads to the emergence of opportunistic diseases, which are so called because they benefit from the progressive inability of a sick person to defend themselves in order to develop these opportunistic diseases are represented by certain infections or cancers, which will weaken further the agency reached.
The virus responsible for AIDS disease is called the AIDS virus or HIV (Human Immunodeficiency Virus).
What characterizes this infection is that it moves silently on a chronic: a person with HIV is not the disease AIDS immediately, it may take several years before the disease does occur.
HIV infection is contagious, even when the infected person is not ill, it can transmit the virus. Transmission is a human being (man or woman) to another human being (man or woman), mostly on the occasion of unprotected sex with an infected partner.
Therefore, it is a sexually transmitted disease (STD). The only means of prevention is the protection of partners during sex with condoms when you do not know their HIV status and that of his partner, if condoms are not used, we talk about relative to risk.
A pregnant woman infected with HIV can transmit the virus to the child she is carrying. The transmission can be done by blood, mostly by sharing a syringe contaminated.
If a person has been infected by the AIDS virus, the virus is present in his body and will be HIV-positive vis-à-vis the virus, ie it has produced antibodies against the virus, HIV.
As long as a body has not been in contact with the AIDS virus, it will be HIV-negative.
A person infected with the AIDS virus, introducing the disease AIDS or not, treated or not, must be monitored regularly by a doctor.
Today through research, new drugs have been on the market, therapeutic protocols were refined. The triple therapy, ie the combination of 3 drugs prescribed simultaneously, as recommended by the experts can reverse the disease AIDS, HIV infection has become a chronic condition. The global AIDS epidemic began in the eighty years. Today, almost 40 million people are infected: homosexual, heterosexual men, women and children. Millions have already dead. Many children are orphans of father, mother or both, died of AIDS. Almost one million are infected.

HIV infection is moving inexorably towards the AIDS disease . AIDS is represented by the emergence of diseases signing a loss of patient capacity to defend itself against infectious diseases and cancers. They are called opportunistic diseases.
AIDS worse when CD4 T cells are too low to enable the organization to defend themselves infected against bacteria or viruses into contact with the body weakened, and may appear tuberculosis, toxoplasmosis, candidacies, a mononucleosis infection, shingles,. Similarly, abnormal cells may no longer be destroyed and cancer will develop more easily.
The decrease in lymphocytes will allow HIV to grow even more easily and more low defenses.
Changes in the number of viruses and defenses in the absence of antiretroviral treatment
Current treatments against HIV help reduce its propagation, the point of rendering the virus undetectable by means of blood test today. But these antiviral treatments do not cure patients infected with HIV, a body infected with HIV keep life and he will always be contaminant even though the virus seems, given blood tests, have “disappeared”.
The goal of treatment, when taken correctly, is: completely control the virus replication: the extent of the viral load in the blood shows that the virus is undetectable. restore the body’s defenses: the extent of CD4 lymphocytes in the blood shows that they are increasing
According to the WHO (World-wide Organization of the Health), about 2.5 African million of Sub-Sahara have AIDS. Africa is, apparently, in the claws of a AIDS pandemic. (In the United States 300,000 people are listed like cases of AIDS).
The AIDS in Africa is portrayed like providing two important lessons for the West. First it is an example of the potential devastation that could untie the AIDS; second it is that by means of I infect heterosexual, the AIDS will finish seizing of the West. Nevertheless, convincing evidence of which million of African are infected with HIV, the putative cause of the AIDS, or of which I infect and distribution of the AIDS of Africa does not exist has a heterosexual origin.
The only evidence of some African “is infected” with a HIV virus is indirect, being based on the random test of the blood of African discovering the presence of antibodies that react with a series of the calls “proteins HIV”.
The discarding of the reactions crossed between “proteins HIV” and the plethora of other present antibodies in the individuals that are exposed of constant way the microbial agents, can only be obtained determining the exactitude of the correspondence between the reactions of the antibodies and the presence or absence of the pure HIV, in itself. In other words, an isolated viral preparation of well-known purity like a “Standard one of Gold” for the reactions of antibodies is due to use. This was never made, or in Africa or in the West, Of such way, nobody knows with security if in Africa the tests of antibodies are specific for the HIV, that is to say, if a positive result really means an infection HIV. Many experts in African AIDS still accepted this fact in the beginnings of the era of the AIDS.
The immunological deficiency can be caused by undernourishment, certain virales infections, and diseases like the malaria and the tuberculosis, all which knows that they exert a strong depressive action on the immunological system. Unlike the West, the AIDS in Africa is diagnosed without no type of laboratory test. The patients classify themselves like cases of AIDS without the laboratory tests that they have, or immunodeficiency or a HIV infection. Everything what is required is to have several clinical conditions.
Ebers papyruses in 1600 before Christ. (In the West, sarcoma Kaposi is restricted the homosexual men). Of the 661 million people in Sub-Sahara Africa, of 2 to 3 million they have an active tuberculosis with an annual mortality of 790,000 people. In spite of this and of the fact that in the adults infection HIV normally follows the TB infection; the tuberculosis has now become a disease that it defines to the AIDS. In fact, from the 30 to 50% of the deaths by African AIDS they are by tuberculosis. Despite all this, the experts in AIDS hope that we accept that something “new” has desem-bacado in Africa and that it is caused by a new agent, HIV. Suddenly, a new enfer-mdad, caused by a new agent has appeared. The old diseases and their pernicious effects on the immune system no longer are more operative.
HIV is affecting the entire world. Many doctors and scientists worldwide have been communicating the importance of taking measures to protect yourself from this deadly virus. Unfortunately, some people don’t seem to be listening. HIV infestation is spreading rapidly in all races, cultures, and economic levels. HIV and AIDS have found their way into all parts of this planet and there have been cases reported among WVU students.
These tests use a small sample of blood taken from a vein in your arm to find out if you’ve been infected with HIV.The tests look for antibodies to HIV, not for HIV itself. HIV antibodies are made by B cells as your body tries to get rid of HIV. Labs use two tests to look for these antibodies. The ELISA test is done first, as a general screening test. (ELISA stands for “enzyme-linked immunosorbent assay.”) If the ELISA test is positive, a second test, called the Western Blot, is done to confirm the results. When both tests are positive, it means that the antibody to HIV has been found. Again, these tests don’t look for the virus itself, but for evidence in your blood that your immune system has reacted to the presence of HIV.
