HIV, or human immunodeficiency virus, is the virus that can lead to AIDS, or acquired immunodeficiency syndrome. The human body is unable to rid itself of HIV.
It is estimated that more than 1.1 million people in the United States are currently living with HIV infection. Of those with HIV, 1 in 5 are unaware that they are HIV positive. Over the past 10 years, the number of new HIV infections on an annual basis has remained stable, while the number of people living with HIV has increased.
