A new American research seems to shed light on the relationship between HIV and alcohol. This report, published by The Lancet, says that countries with higher levels of HIV patients have at the same time, high alcohol consumption.

According to Dr. Katherine Fritz, the properties of alcohol may explain part of the widely observed association between alcohol use and risky sexual behavior. This would involve sex without adequate protection, having sex with different partners and the commercialization of sex.

Past studies had found that alcohol abuse is common among people with HIV. As mentioned, those who abuse this substance are more likely to perform risky behaviors. For this reason, researchers believe they have a higher risk of acquiring the disease.

As a solution the researchers propose to develop strategies such as those implemented by the gay bars in the United States during the 90s. These complemented the HIV prevention programs with those to combat alcohol abuse.

Moreover, the abuse of alcohol also increases the risk of sexual violence against women (by their partners). For this reason researchers believe that it is also necessary to conduct more studies on gender and alcohol abuse.

This discovery may open the door to new treatments to prevent sexual transmission of the virus, because in laboratory tests this substance has proved to be as powerful as other anti-HIV drugs in use today (the T-20 or maraviroc).

It was known that this family of substances have the property of binding to sugars on the cover of infectious agents, thus facilitating detection and destruction by immune system cells. And what they have done the Michigan researchers is to test it with HIV, and compare the effect of two existing antivirals (with the difference that these drugs are used topically, they are injected or ingested).

If the results are confirmed, this compound could be used in the manufacture of microbicides, gels Vaginal leading studied over a decade to curb the sexual transmission of the virus.

Michael Dawson, the program in immunology at the University, says that these substances, which are already registered, may have another advantage: its mechanism is much less specific than anti-virals, it is possible that the virus will mutate more difficult to escape action.

HIV is known for over 20 years. At that time HIV in the Netherlands only transmitted through blood, breast milk, semen and vaginal fluid. A screening takes place to ensure that safe blood and organs. Transfer of the HIV virus is only possible if the amount of virus that enters the blood directly is large enough.

If an infected child must incur a cut wound in the usual manner with standard first aid and hygiene measures are discussed. This method is effective in preventing transmission of all blood-borne infections, including HIV.

An infected child at school is no risk to staff or students. As said before: there is no case of HIV transmission at a Dutch school yet. There has never been a reported case of HIV transmission from child to child through biting, fighting, games or any other form of normal handling of children among themselves whatsoever.

Children who are injured or playing with injection material forms a major problem in the transfer of certain blood-borne viruses, but not with HIV. The success of needle exchange programs, the number of new HIV infections among intravenous drug users with low (Health Protection Agency and others, 2004). HIV can not go against oxygen and thus remains outside the body longer than a few minutes alive.

HIV is a sexually transmitted infection. Sexual and relationship education should provide students knowledge and skills which they can protect themselves from infection with the virus through unsafe sex.

Symptoms of AIDS

• There are no specific symptoms of HIV
• The only way to confirm the existence of HIV is through testing for HIV in a blood sample.
• There are no specific symptoms of AIDS
• The only way to confirm the existence of HIV infection through HIV testing in a blood sample. It is important to have enough information about AIDS as a disease that is caused by the virus HIV (Human Immunodeficiency Virus)
• Some people reported that they had submitted a flu-like box between 2 and 5 weeks after infection (risk of contact). But not usually pay attention to this table because the reported cases represent only 10% of infections and symptoms would be like the flu. Therefore, the only way to know if there is infection be tested for HIV three months after exposure risk.
• There is no associated symptoms of infection, it is said that this infection is asymptomatic.
• However, transmission risk does exist if the person has symptoms of AIDS.
• Some people reported that they had submitted a flu-like box between 2 and 5 weeks after infection (risk of contact) as symptoms of AIDS. But not usually pay attention to this table because the reported cases represent only 10% of infections and symptoms would be like the flu. Therefore, the only way to know if there is infection be tested for HIV three months after exposure risk.
• Many people infected have no symptoms of AIDS, especially in the early years and in general for a long time.

The virus is weakening the immune system would slowly and after an average of 8-10 years without treatment (the disease had evolved and would be badly damaged immune system) when the following symptoms appear:

• sudden weight loss over 10%
• Fever or night sweats for more than a month
• or chronic diarrhea for more than a month
• acute or persistent fatigue
• Other symptoms of AIDS or effects: dry cough for over a month, hives, mouth ulcers, mouth and throat fungus, herpes and swollen glands.

The person looks and feels completely healthy but any person with HIV can transmit the virus. The virus is slowly weakening the immune system. When the immune system has deteriorated, is more susceptible to illnesses, especially infections (eg tuberculosis and pneumonia) and tumors.

AIDS : is an advanced stage of disease. It means that, as a result of immunodeficiency, the person has one or more of a list of rare diseases, which are called AIDS defining.

AIDS Information: There are 2 types of virus: HIV-1 is the most common in Spain and HIV-2 is located mainly in West Africa and generally produces a milder variant of the disease. Since 1981 the human immunodeficiency virus ravages the world.

The three main forms of transmission are:

• Sexual (unprotected sex). View (sexually transmitted disease). The disease is spread by contact with infected secretions, genital mucosa, rectal or oral sex the other person.
• Parenteral (by blood). It is a way of transmission through contaminated syringes given by intravenous drug use or through health services, as has happened sometimes in poor countries, do not use the best measures of hygiene also people, like hemophiliacs, who received a transfusion of contaminated blood products contaminated blood products, and to a lesser extent health care workers who are exposed to infection as an occupational accident may occur if a wound comes into contact with contaminated blood, and also during the realization of piercings, tattoos and scarification.
• Vertical (mother to child). Contamination can occur during the last weeks of pregnancy, childbirth, or breastfeeding. In these situations, childbirth is the most problematic. Currently developed vertical transmission of HIV is completely controlled (if the mother is a known carrier of the virus) because since the beginning of pregnancy (and in some cases even earlier) is given to pregnant women treated with an anti – highly active antiretroviral therapy (HAART) particularly suitable for these situations, the delivery was by Caesarean section are generally suppresses the production of milk, and thus breastfeeding, and even antiviral treatment is given to the newborn.

Since 1981, cases were detected striking infection Pneumocystis jiroveci (formerly named Pneumocystis carinii), a fungus related to the original forms of the Ascomycetes, known to infect severely immunocompromised patients. Initially there was a group of similar cases in which gay men were involved and where time appeared to cytomegalovirus infection, and Candidiasis. First thought that the cause should be linked to common practices among male homosexual population.

He soon began to appear cases involving heterosexual male or female intravenous drug users and their children, and also between patients and healthy habits homosexuals who had received transfusions of whole blood or blood products by hemophiliacs condition. Soon it was thought, by epidemiological criteria basically, that the cause must be an infectious agent transmitted in a similar way as does the hepatitis B virus
HIV-1 virions assembled at the surface of a lymphocyte.

Several teams started to get a virus associated with known cases of acquired immunodeficiency, perhaps as a retrovirus known to be produced immunodeficiency cat or HTLV, producer of a type of leukemia. In 1983, at the Pasteur Institute in Paris, a team dedicated to investigating the relationship between retroviruses and cancer led by JC Chermann, F. Barre-Sinoussi, and L. Montagnier found a candidate who called lymphadenopathy-associated virus (lymphadenopathy-associated virus, LAV).

In 1984 the team of R. Gallo, discoverer of HTLV, the only human retrovirus known then, confirmed the discovery, but calling the virus human T lymphotropic virus type III (human T-lymphotropic virus type III, with the acronym HTLV-III). There was a subsequent dispute over the priority in which it became clear that Gallo had described the virus only after receiving samples from the French. As part of resolving the conflict, the virus acquired its final name, human immunodeficiency virus (HIV) in Castilian is expressed as human immunodeficiency virus (HIV).

In the same year, 1983, which identified the virus, several teams began work on its genome sequence published in early 1985, and also began the characterization of proteins.
