Aids- a Global Phenomenon

Human Populations and a Global Phenomenon: AIDS

Acquired Immune Deficiency Syndrome (commonly known as AIDS) is a collection of symptoms and infections resulting from the damage to the immune system caused by the Human Immunodeficiency Virus (HIV) which attacks the body’s immune system leaving individuals vulnerable to opportunistic infections which usually results in death.
It was found that not everyone with HIV has AIDS, but everyone with AIDS has HIV. HIV is transmitted through direct contact of the bloodstream with bodily fluid such as: blood, semen, vaginal fluid, pre-seminal fluid and breast milk of a HIV positive person, during sexual intercourse, the sharing of contaminated needles, tattooing, child birth, breast feeding, intravenous drug use and blood transfusions.

Since it originated from Sub-Saharan Africa in 1981, AIDS has been reported in over 150 countries worldwide (including the most populous countries, such as China, India and Russia) and has claimed the lives of approximately 25 million people, making it one of the most widespread and destructive epidemics in recorded history.

19.5 million infected with AIDS were found to be men (over 15 years), 17.7 million were found to be women (over 15 years) and 2.3 million were found to be children (under 15 years).
