Because the HIV virus is the cause of AIDS, statistics for HIV infection include people at all stages of the disease, including those in early stages and those in whom HIV has progressed to AIDS. (CDC)
Here is a summary of some key AIDS and HIV statistics:
• More than one million people in the U.S. currently have HIV.
• 1 in 5 people with HIV don’t know they are infected.
• Someone is infected with HIV in the United States every 9 ½ minutes.
The CDC also tracks HIV and AIDS infection based on several different categories:
• Risk Factors
Men who have sex with men (MSM) are in the highest risk category for HIV infection. Although only 4 percent of U.S. men are in this category, MSM are more than 44 times as likely to develop HIV as other groups.
