The following one is a list of infections and cancers related to the AIDS that the people with this disease acquire as its count of CD4 falls. Previously, to have AIDS was defined as having infection by HIV and acquiring one of these additional diseases, but at present it is defined additionally as having a count of CD4 below 200, even without the presence of an opportunistic infection. Many other diseases and their respective symptoms can be presented/displayed besides which they appear in this list. Common with CD4 count inferior to 350 cellules/ml: Virus of the herpes simple: cause ulcers or vesicles in the mouth or the genitals; one appears with more frequency and severity in a patient infected with HIV that before the infection. Tuberculosis: infection with the bacterium of the tuberculosis that predominantly affects the lungs, but can affect to other organs like the internal, the coating of the heart. Treatment   Until this moment, it does not exist of cures for AIDS. Nevertheless, are available several treatments that can slow down the progress of the disease by many years and improve the quality of life of those people who have developed symptoms? The antiretroviral therapy inhibits the replication of virus

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 United States. Around 25 million people anywhere in the world they have died because of this infection from the beginning of the epidemic and 40,3 million people are at the moment living with HIV/SIDA in global terms.  Human immunodeficiency virus   (HIV) causes AIDS. This virus attacks the immune system and leaves to the vulnerable organism to a great variety of infections and potentially mortal cancers. The common bacteria, the levaduriformes fungi, the parasites and the virus that generally do not bring about serious diseases in people with an immune system that works normally can bring about mortal diseases in the people with AIDS. One has been HIV in salvation, tears, weave of the nervous system, blood, semen (including the preseminal liquid), vaginal flow and maternal milk.  Nevertheless, only through the blood, the vaginal semen, secretions and maternal milk the contagion with other people appears. The transmission of the virus happens: Through sexual or oral contact, vaginal or anal manner.  A pregnant woman can transmit the virus to her fetus through fact to share the circulation of the blood or a nursing mother can transmit it to her baby by milk. There is other little common transmission methods like an accidental injury with a needle, artificial insemination by a donated semen and through transplants of organs. The infection by HIV does not propagate by accidental contact like a hug, to touch to things that have been touched previously by a person infected with the virus, neither during the participation in sports nor by mosquitoes. One does not transmit the people who DONATE blood or organs. The people who donate organs do not enter direct bonding with they receive which it. In the same way, anybody that donates blood does not have contact with it receives which it. In all these procedures sterile needles and instruments are used. Nevertheless, HIV can be transmitted the person who RECEIVES blood or organs of an infected donor. It is by that the blood donation points and the programs of donation of organs make meticulous examinations to the donors, the blood and the weaves. Between that they are in the group with greater risk they can mention: Those that have sex without protection The sexual companions of people who participate in activities of high risk (like anal sex) The intravenous drug users that share the needles The children born from mothers with HIV who did not receive the therapy for HIV during the pregnancy People who received sanguineous transfusions or hemoderivados between 1977 and 1985 (before the establishment of the evaluations standard to look for the virus in the blood). AIDS begins with an infection by HIV. It is possible that the people infected with HIV do not present/display symptoms during 10 years or more, although yes can transmit the infection to others during this asymptomatic period. In the meantime, if the infection is not detected and the treatment begins, the immune system is debilitated gradually and AIDS is developed. The acute infection by HIV progresses with time to an infection by asymptomatic HIV and soon to early symptomatic infection by HIV. Later, it progresses to AIDS (defined like the infection by HIV very outpost with count of cells T below 200). The majority of the individuals infected with HIV and without treatment will develop AIDS. There is a small group of patients who very slowly develop AIDS or that develop never it. To these individuals it is called patients to them without progression of the disease and many seem to have a genetic difference that it avoids that the virus adheres to certain immune receivers.    

Symptoms  

 The symptoms of AIDS are mainly the result of infections that normally are not developed in people with a healthy immune system. These are called “opportunistic infections “. HIV exhausts the immune system of the patients with AIDS, who are very susceptible to these opportunistic infections. The common symptoms are fever, perspiration (particularly at night), inflamed glands, chills, weakness and loss of weight. It is possible to be sent to the section of signs and examinations next to see a list of the common opportunistic infections and the main symptoms associated with them. Note: The initial infection with HIV can be asymptomatic. Nevertheless, the majority of the people yes undergo symptoms similar to the influenza with fever, coetaneous eruption, irritation of throat and inflammation of the lymphatic ganglia, generally two weeks after contracting the virus. Some people with infection by HIV remain per years without symptoms between the time of the exhibition and the development of AIDS.

Epidemiology of AIDS/HIV

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.
 After peaking in 1994, the number of new cases gradually decreases.
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 HIV status of women is discovered earlier than men, thanks to more regular medical monitoring and the onset of pregnancy, which makes them see.
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.
 The use of combination antiretroviral assets can control the virus and delaying the disease. There has been a significant drop in mortality linked to AIDS. However, the population infected by the AIDS virus is getting older and it appears diseases as varied as a result of natural aging patients the side effects of treatment and the development of the infection itself.

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. 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.
The African region sub-Saharan
Africa is particularly affected.

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

AIDS/HIV and Africa

Author: admin
April 17, 2008

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”.  If “proteins HIV” (present in kits of test) only reacted with antibodies HIV, there would not be any problem. Unfortunately, this it is not the case. The antibodies produced in answer to the presence of some strange agent can also react with other different strange agents; and the infectious agents to whom a person has been exposed, greater are the possibility that those antibodies of crossed reaction exist.

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.    At the beginning of this years Myron Essex, an important investigator and his colleagues of the University of Harvard, when they discussed his experimental datas on tests of the antibody of the AIDS in Africa, again warned that tests of antibodies “can not be sufficient for the diagnosis of HIV in the endemic areas of AIDS of the Central Africa, where the prevalence of microbacterial diseases (leprosy, tuberculosis, malaria and others whose antibodies can give crossed reactions) is extremely high.” Thus, the certainty that does not exist the African really are infected with a new putative agent, HIV. The experts in AIDS also agree in which the acquired immunological deficiency (the “GOING” in AIDS) also has a data in Africa.

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.    But the accepted conditions to form the “S” (syndrome) of “AIDS” in Africa, do not have any relation with the AIDS in the West. In the West, the AIDS is diagnosed if a person has one or more of approximately 27 relatively rare diseases. Nevertheless, the AIDS diagnoses in Africa in agreement the definitions “Bangui 1989/87″ of the WHO that can be described better like a set of nonspecific common symptoms, like cough, fever, diarrea, tuberculosis (TB) and a cancer known like “sarcoma Kaposi”. Tdas these diseases have been endemic in Africa for centuries. Sarcoma Kaposi, for example, was described in the dated

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.   Many experts in AIDS also hope that we created that, unlike history in the West, Africa the AIDS expands of predominant way, by heterosexual contact. In truth, since the number of cases in the West is too small to be statistically significant, the “African evidence” is used to foretell the same predicament in the West. The affirmation of the heterosexual expansion in Africa is based on the “absence of homosexual transmission or intravenous drugs”, and approximately the equal number of seropositivos men and women who also have AIDS like tests for antibodies. This last certainly test that the AIDS has a heterosexual expansion - the influenza and the appendicitis does not have also the same distribution in sexes. Given the beacon of which tests of seropositivos antibodies can be due to the presence of antibodies formed in answer to the malaria, tuberculoses, leprosy, and many parasitic diseases, are not surprise that an equal number of men and women will be diagnosed with “AIDS” according to symptoms that have centuries of antiquity, and have a positive test of antibodies. In any case, the theory that AIDS in Africa is transmitted of heterosexual way creates more problems for theory HIV of the AIDS that those that solves. One says that a disease is caused by a sexual signal officer if one of the infected parts, we say the active part (the man) transmits the agente/enfermedad to the passive part (woman), that another man as well transmits to the agente/enfermedad. This is, the diseases of sexual transmission are transmitted bidirectionally, of man to woman to man. In the West, the studies epidemiologists greater (thousands of cases), lead of the most judicious way, have proven beyond any reasonable doubt that, as much in men as in women, the only act that take to the acquisition of “antibodies HIV” (women) and “antibodies HIV” and possible AIDS (homosexual men) it is the passive anal copulación (receptive). In other words, in the West, the “antibodies HIV” and the AIDS, miso that the pregnancy, only can be acquired by the passive partner. If, the other way around of the pregnancy, “antibodies HIV” are not caused by a noninfectious agent (sperm, semen) but by HIV, then the HIV will be the only transmitted infectious agent unidirectionally by means of sex. The active member will have to acquire to the HIV by other means.   This is enough stranger: in all the history of the medicine never there was a agente/enfermedad of sexual transmission that has been transmitted of unidirectional way in the West and bidirectionally in Africa. Only the other alternative to this ridiculous scene is to be in agreement with seropositivos the African doctors who tests of HIV in Africa do not mean infection with, and which the inmunodepre-sión and certain symptoms and diseases that constitute the African AIDS have existed in Africa from immemorial times. In agreement with Professor P.A.K. Addy, head of Clinical Microbiology of the University of Science and Technology, in Kumasi, Ghana: “European and the Americans come to Africa with prejudiced minds, so that they are seeing what they want to see… I have known for a long time that the AIDS is not a crisis in Africa, as it has been wanted to him to make include/understand to the world. But in Africa it is very difficult to stretch the neck and to say some things. The West came with all those terrifying statistics on the AIDS in Africa because it was not to as much of certain social and clinical conditions. In most of Africa, the infectious diseases, in individual the parasitic ones, are common. And there are other conditions that can jeopardize with facility or affect the immunological system.”    The Dr Konotey-Ahulu, of the Cromwell Hospital of London, expresses a similar vision: “At the moment, because of the AIDS, it seems that to the African more is not allowed them to die because of these conditions [ of which was used to dying before the era of the AIDS ]. If tens of thousands are dying of AIDS (and the African they do not cremate to its deads) where they are the tombs ” According to him, the most important question in the mind of African and European the intelligent ones in that continent is: “Why the means of press of the world seem to have conspired with some scientists to have turned so gratuitously outlandish with the lie”

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. It has been the consensus of doctors and scientists worldwide that an effective way to protect yourself from HIV is to abstain from anal, vaginal, or oral sex with people whose HIV status you are unsure of and to refrain from sharing intravenous needles. If you have sex with an unfamiliar partner, a latex condom may reduce the risk of HIV transmission. Symptoms of HIV/AIDS can manifest themselves in a number of ways. Symptoms include: fatigue, night sweats, diarrhea, sores in the mouth, and recurrent fever. However, these symptoms are associated with many other illnesses. If you suspect you are at risk of having HIV, you can get an HIV antibody test. This is a blood test that indicates the presence of antibodies produced by your body that try to fight HIV. If you are considering being tested, talk to a qualified counselor or health care worker. The results of the test may have an impact on your lifestyle. A negative result may open your eyes to a more cautious way of life. A positive diagnosis may require initiation of a powerful medication program (most HIV/AIDS treatments have serious side-effects). Skilled counselors (like those at University Health Services) may help students with this frightening issue. If you have questions about HIV antibody testing or HIV/AIDS in general, call University Health Services at 293-2811. Currently, an HIV positive diagnosis means full blown AIDS is probable. However, some of the worlds’ best scientists are working relentlessly to end the tragic assault of HIV on humanity. Bubonic plague, polio, small pox, and anthrax are some horrible diseases that human resourcefulness has conquered. It may only be a matter of time before HIV succumbs to advancing medical technology - but don’t let that cause you to be careless now!

Tests for HIV infection

March 29, 2008

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.

 Viral load tests show how much virus is in your blood. They can show whether you’re infected, even if your immune system hasn’t made antibodies to HIV. Remember that these tests look for HIV only in your blood, not in your lymphatic tissue. It is not clear at the time of writing whether these tests will be covered by provincial or private insurance plans.

Does HIV cause AIDS

  Historically there has been some debate about the relationship between HIV and AIDS. Many people, but not everyone, believe that HIV causes AIDS. Some people say HIV can’t cause AIDS by itself, but can do so in combination with other things, called co-factors (such as different germs).
