AIDS (acquired immunodeficiency syndrome) was first reported in the US in 1981 and has since reached epidemic proportions, causing major concern worldwide. AIDS is caused by HIV (human immunodeficiency virus), a virus that attacks the immune system of the body, weakening its ability to fight infection; the most advanced stages of HIV infection lead to AIDS. According to the Centers for Disease Control, over 1 million Americans were living with HIV/AIDS at the end of 2003 and an estimated 35,000 new cases were reported in the United States in 2006.
Transmission of HIV/AIDS varies from unprotected sexual activity to sharing hypodermic needles with infected persons to transmission from mother to child during pregnancy. While many organizations and institutions provide resources about transmission, risks, preventative measures, and testing, HIV and AIDS are still of great concern today. With infection rates growing rapidly amongst minorities and in developing nations, HIV and AIDS raise important issues that move beyond the disease itself, including health care access and funding, public health programs, sexual education, and social conditions.
