HIV / AIDS

What is AIDS?

AIDS (acquired immune deficiency syndrome) is caused by the human immunodeficiency virus (HIV), which kills or impairs cells of the immune system and progressively destroys the body’s ability to fight infections and certain cancers. HIV is most commonly spread by sexual contact with an infected partner.

The term AIDS applies to the most advanced stages of an HIV infection. Official criteria for the definition of AIDS are developed by the Centers for Disease Control and Prevention (CDC), which is responsible for tracking the spread of AIDS in the United States. The 1993 CDC definition of AIDS includes all HIV-infected people who have fewer than 200 CD4+ T cells. (Healthy adults usually have CD4+ T-cell counts of 800 or more.) In addition, the definition includes 26 clinical conditions that affect people with advanced HIV disease.

According to the CDC, at the end of 2006, an estimated 1.1 million adults and adolescents were living with HIV/AIDS in the United States. An estimated 2.7 million new HIV infections occurred worldwide during 2007, which equates to about five new infections every minute. This indicates that the AIDS epidemic still rages out of control. At the end of 2007, there are 33 million people living with AIDS globally.

Treatment for HIV/AIDS:

As with many other conditions, early detection offers more options for treatment. Today, there are medical treatments that can slow down the rate at which HIV weakens the immune system, but currently there is no cure for the disease. However, there are other treatments that can prevent or cure the conditions associated with AIDS. Consult your physician for more information regarding various drug therapies for the treatment of HIV/AIDS.
