How long does a person with AIDS have to live?

The life expectancy of the patient 10 years ago was established at 12 to 15 years from diagnosis, nowadays it is at least 40 years more from diagnosis, which can practically equate to the life expectancy of a normal person.

Signs and symptoms of HIV

In fact, the average incubation time from contracting the virus until signs of AIDS occur in adolescents and adults is 10 to 11 years. This means that many young adults may not know they are infected and can spread HIV to others.

What are the stages of AIDS?

The three phases of HIV infection are 1) acute infection, 2) chronic infection and 3) acquired immunodeficiency syndrome (AIDS).

Virus life cycle

Antiretroviral therapy (ART) is the use of anti-HIV drugs to treat HIV infection. People on ART receive a combination of anti-HIV drugs (known as an anti-HIV treatment regimen) every day. Anti-HIV drugs protect the immune system by blocking the virus at different stages of its life cycle.

Because an HIV treatment regimen includes anti-HIV drugs from at least two different classes of drugs, ART is very effective in preventing HIV from multiplying. A lower concentration of HIV in the body protects the immune system and prevents the virus from developing into acquired immunodeficiency syndrome.

ART cannot cure HIV infection, but drugs to treat HIV help people with HIV live longer, healthier lives. Anti-HIV drugs also reduce the risk of HIV transmission (spread of the virus to others).

The human immunodeficiency virus (HIV) attacks the immune system and weakens defense systems against infections and certain cancers. As the virus destroys immune cells and prevents normal immune function, the infected person gradually falls into a state of immunodeficiency. Immune function is usually measured by the CD4 lymphocyte count.

As the infection weakens the immune system, the person may develop other signs and symptoms, such as swollen lymph nodes, weight loss, fever, diarrhea and cough. In the absence of treatment, serious diseases such as tuberculosis, cryptococcal meningitis, severe bacterial infections or cancers such as lymphomas or Kaposi’s sarcoma, among others, may develop.

AIDS stands for acquired immunodeficiency syndrome and defines the series of symptoms and infections 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.
