How much does AIDS research cost?

No preventive HIV vaccine has been approved by the U.S. Food and Drug Administration (FDA) at this time, but research is ongoing. You must be enrolled in a clinical trial to receive a preventive HIV vaccine.

A preventive HIV vaccine is given to people who do not have HIV infection, while a therapeutic HIV vaccine is given to people who already have HIV infection. The goal of a therapeutic HIV vaccine is to boost a person’s immune response to HIV already in his or her body. Researchers are studying the use of therapeutic HIV vaccines:

Proper use of condoms and pre-exposure prophylaxis (PrEP) can help prevent HIV transmission. However, researchers believe that a preventive HIV vaccine would be the most effective way to completely end new HIV infections.

How much does AIDS medication cost?

To give an example, Truvada, a drug used both for the treatment of HIV and to reduce the risk of infection in people exposed to a high risk of contracting it, costs approximately 9,000 pesos.

Why is it so difficult to cure AIDS?

The problem is that AIDS can hide in cells, which complicates its detection and drugs cannot fight it. The “Mississippi Girl” is again undergoing treatment because the viral load is too high and the original treatment failed to attack the hidden reservoirs of the virus.

How long does it take for AIDS to appear?

The time can vary widely depending on the individual. Between HIV infection and the development of the first symptoms of AIDS there can be 10 to 15 years, sometimes more, sometimes less.

Treatment of hiv

AIDS stands for acquired immunodeficiency syndrome and defines the series of symptoms and infections that are associated with acquired immune system deficiency. HIV infection is considered the underlying cause of AIDS. The level of immunodeficiency and the occurrence of certain infections are used as indicators of whether HIV infection has progressed and caused AIDS (see question 4).

HIV infection causes progressive depletion and weakening of the immune system. This leads to increased susceptibility of the body to infections and cancers and can lead to the development of AIDS (see questions 2 and 4).

AIDS is identified on the basis of certain infections. Stage I HIV disease is asymptomatic and is not considered AIDS. Stage II (includes mild candidiasis and frequent upper respiratory tract infections), stage III (includes chronic unexplained diarrhea persisting for more than one month, various bacterial infections and pulmonary tuberculosis) and stage IV HIV disease (includes cerebral toxoplasmosis, candidiasis of the esophagus, trachea or lungs and Kaposi’s sarcoma) are used as indicators of AIDS. Most of these conditions are easily treatable opportunistic infections in healthy individuals.

AIDS prevention

The Human Immunodeficiency Virus (HIV) is the causative agent of Acquired Immunodeficiency Syndrome (AIDS), a human disease characterized by the presence of low levels of CD4 lymphocytes associated with the development of opportunistic infections and some types of cancer.

There are different genetic variants of HIV. At the first level of classification, there are HIV-1 and HIV-2 infections, with HIV-1 being the most frequent worldwide. In turn, there are various subtypes and recombinant forms of HIV-1, with subtype B being predominant in economically developed countries and the various non-B subtypes and recombinant circulating forms (CRFs) causing most cases of infection in developing countries.

HIV infection is transmitted sexually (homosexual and heterosexual), parenterally (blood, blood products, injecting drug users) and through mother-to-child transmission (during pregnancy, childbirth or breastfeeding), with sexual transmission being the most common route worldwide.

AIDS: symptoms

We are an international leader in research for the eradication of HIV/AIDS and related diseases. We also work in the fields of specialized training, prevention and innovation.

We develop research excellence based on a combined strategy to move towards the eradication of HIV/AIDS and related diseases. Our work focuses on 5 main axes.

HIV-1 infection is beginning to spread in Central and West Africa through the transmission of simian immunodeficiency virus (SIVcpz) from a subspecies of chimpanzees to humans.

French virologists Luc Montagnier and Françoise Barré-Sinoussi of the Institut Pasteur in Paris identify HIV as the etiological agent of acquired immunodeficiency syndrome. Montagnier sends samples to the American scientist Robert C. Gallo, who helps to conclude that HIV is the cause of AIDS.

Highly active combination therapy (HAART) is introduced, dramatically reducing AIDS morbidity and mortality. In high-income countries, the disease goes from fatal to chronic.
