Prevalence is the number of people living with HIV infection at the end of a given year. According to the CDC, at the end of 2006, an estimated 1,106,400 persons in the United States were living with HIV infection, with 21% of people undiagnosed. Incidence is the number of new HIV infections that occur during a given year. In 2008, the CDC estimated that approximately 56,300 people were newly infected with HIV.

Definition/Description[edit | edit source]
AIDS is a chronic, life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight off viruses, bacteria and fungi that cause disease. HIV makes you more susceptible to certain types of cancers and to infections your body would normally resist, such as pneumonia and meningitis. The virus and the infection itself are known as HIV. "Acquired immunodeficiency syndrome (AIDS)" is the name given to the later stages of an HIV infection.
An estimated 39.5 million people have HIV worldwide. And though the spread of the virus has slowed in some countries, it has escalated or remained unchanged in others. The best hope for stemming the spread of HIV lies in prevention, treatment and education.
