My project is close to my heart, because this virus has affected a lot of young people. This virus still exists and still affects too many people, despite our ressources today.

This virus is AIDS (The acquired immunodeficiency syndrome) :

+Introduction : Acquired Immunodeficiency Syndrome, better known by its acronym AIDS, is a set of symptoms resulting from the destruction of immune system cells by the Human Immunodeficiency Virus (HIV).//


*What is this virus ?

  • How is it transmitted ?
  • When did it first appear ?
  • Is it dangerous ?**


HIV, or human immunodeficiency virus, is a type of virus that can cause a disease called AIDS (acquired immunodeficiency syndrome). HIV infection affects the immune system, the body's natural defences against disease. If left untreated, serious illness can occur. Normally harmless infections, such as the flu or bronchitis, can get worse, become very difficult to treat or even lead to death. In addition, the risk of cancer is also increased.

What distinguishes HIV from other viruses is that it affects the immune system by taking control of CD4 T cells. The role of CD4 T cells is to coordinate the immune response when a virus presents itself. When HIV uses CD4 cells to spread, it damages and destroys them. In doing so, HIV undermines the immune system from within, which is responsible for fighting it.


HIV is transmitted through body fluids: blood, semen, vaginal secretions and breast milk. These body fluids only transmit HIV if they come into contact with an area that allows HIV to enter the body, a mucous membrane. Healthy skin is impermeable to HIV.

Most often, the virus is contracted through unprotected sexual activity or was contracted in the past through needle exchange among injection drug users. The risk of transmission through kissing with saliva exchange is zero.

In most industrialized countries, anal intercourse between men is the most important route of HIV transmission. However, heterosexual transmission has increased sharply since the beginning of the epidemie.


In North America, the first signs of the epidemic appeared in the late 1970s. Men who have sex with men (MSM) were the first to be affected;
The HIV virus was isolated in 1983.
The first antiretroviral treatment, AZT, was discovered in 1987. Triple therapy, a much more effective multi-drug combination, became available in the mid-1990s, and increasingly potent antiretroviral therapy (ART) suggests that an HIV-positive young adult starting treatment early may live to be 80 years of age or older. These treatments often result in an undetectable viral load, even though the virus has not yet been eradicated from the body.
35 millions peoples worldwide are now living with HIV. Two-thirds of them live in sub-Saharan Africa1.
In North America, 1.3 millions peoples are living with HIV, in Western and Central Europe, 840,000, and in sub-Saharan Africa 22.9 million.
In France, 150,000 people are living avec HIV, so 50,000 are not being monitored and therefore not treated.
The number of HIV-positive people is increasing worldwide, with 2.5 million new infections per year and 1.5 million deaths. This is due to the considerable improvement in the effectiveness of treatment.
Approximately 7,000 HIV-positive discoveries in France (2012 figures), nearly half of which are among MSM (men who have sex with men), and 3,000 AIDS deaths in the year.
In Canada, 71,300 people were living with HIV in 201136. An estimated 3175 new infections are expected to occur in 2011. However, this underestimates the true number of cases, as an estimated 25% of Canadians infected with HIV are unaware of their infection.




1 phase :
primary infection. In the weeks following the infection, about a third of those affected have symptoms similar to those of influenza or mononucleosis: fever, headache, sore throat, redness of the skin, fatigue, muscle aches, etc. These symptoms disappear on their own, even without treatment.

2nd phase :
asymptomatic infection. The virus can live in the body for many years without causing symptoms. The person may therefore feel as though they are not sick, but they are likely to transmit HIV. Seroconversion - the point at which an HIV-negative person (no antibodies in the blood) becomes HIV-positive (antibodies in the blood) - occurs during this phase, 1 to 3 months after infection.

3rd phase :
AIDS (Acquired Immune Deficiency Syndrome) or symptomatic infections. If still untreated, the person experiences symptom(s) related to HIV infection (fatigue, diarrhea, swollen lymph nodes, weight loss, night sweats, fever, etc.).

Phase 4 :
If the number of immune cells (CD4 T cells) becomes very low and the body is no longer able to fight off other infections or diseases, the diagnosis of AIDS is made. Symptoms of the infection become more apparent and constant. In addition, opportunistic infections can cause significant health problems. Opportunistic infections are infections that are usually not serious, but become serious in people with very weak immune defences. Examples of opportunistic diseases include candidiasis, pneumonia, tuberculosis, herpes infections, and also cancers (including lymphomas and Kaposi's sarcoma).

Note. Research has shown that cardiovascular disease is more common in people with HIV because their bodies are subject to a higher degree of inflammation. Inflammation is known to contribute to the formation of plaque in the walls of arteries, which can interfere with blood flow. In addition, cases of cognitive degeneration (e.g. Alzheimer's disease) related to HIV infection have also been reported

conclusion :
since the 1980s, researchers have been struggling to find cures. That's why there are a lot of associations and charity events (ex: races, donations…).
So let's protect ourselves against AIDS and above all protect ourselves, it's also important to get tested as soon as possible.This mobilization becomes more important from the first of December.
