Abstract: AIDS was first reported in the United States in 1981 and has since become a major worldwide epidemic. AIDS is caused by the human immunodeficiency virus (HIV). By killing or damaging cells of the body's immune system, HIV progressively destroys the body's ability to fight infections and certain cancers. AIDS is caused by HIV infection and is characterized by a severe reduction in CD4+ T cells, which means an infected person develops a very weak immune system and becomes vulnerable to contracting life-threatening infections (such as Pneumocystis carinii pneumonia). AIDS occurs late in HIV disease. The HIV-1 pandemic is a complex mix of diverse epidemics within and between countries and regions of the world, and is undoubtedly the defining public-health crisis of our time. Our aim of this study to give an overview about the impacts of AIDS on the world population extracted based on previous studies.
Keywords: HIV, AIDS, virus, body's ability, damaging cells, body's immune system.
