Statistics on HIV/AIDS and percentage of population infected

by Matt Slick

1. Number of people infect with HIV
   1. 2008, over 1.1 million in U.S. is infected with HIV: "At the end of 2008, an estimated 1,178,350 persons aged 13 and older were living with HIV infection in the United States. Of those, 20% had undiagnosed HIV infections." (Center for Disease Control, cdc.gov/hiv/topics/surveillance/basic.htm#exposure)
2. "Percentage of Homosexual Infected is much higher than non homosexual Population."
   1. 2% of U.S. population is gay has largest % of HIV infection: "Gay, bisexual, and other men who have sex with men (MSM) represent approximately 2% of the US population, yet are the population most severely affected by HIV and are the only risk group in which new HIV infections have been increasing steadily since the early 1990s. In 2006, MSM accounted for more than half (53%) of all new HIV infections in the United States, and MSM with a history of injection drug use (MSM-IDU) accounted for an additional 4% of new infections. At the end of 2006, more than half (53%) of all people living with HIV in the United States were MSM or MSM-IDU. Since the beginning of the US epidemic, MSM have consistently represented the largest percentage of persons diagnosed with AIDS and persons with an AIDS diagnosis who have died." (Center for Disease Control, http://www.cdc.gov/hiv/topics/msm/index.htm)
   2. Homosexual men 44 -86 times more likely to be infect with HIV:  "In 2007, MSM [Men Sex with Men] were 44 to 86 times as likely to be diagnosed with HIV compared with other men, and 40 to 77 times as likely as women." (Center for Disease Control, http://www.cdc.gov/hiv/topics/msm/index.htm)
   3. 61% of new HIV infections occur with gay and bisexual men: "Incidence is the number of new HIV infections that occur during a given year. CDC estimates that approximately 50,000 people are newly infected with HIV each year in the United States. In 2009 (the most recent year that data are available), there were an estimated 48,100 new HIV infections.1  Most (61%) of these new infections occurred in gay and bisexual men. Black/African American men and women were also strongly affected and were estimated to have an HIV incidence rate than was 7 times as high as the incidence rate among whites. Visit the HIV incidence page for more details." (Center for Disease Control, cdc.gov/hiv/topics/surveillance/basic.htm#exposure)
3. Percentage of HIV infected
   1. 2% of U.S. population is gay yet it accounts for 61% of HIV infection:  "Men who have sex with men remain the group most heavily affected by new HIV infections. While CDC estimates that MSM represent only 2 percent of the U.S. population, they accounted for the majority (61 percent; 29,300) of all new HIV infections in 2009. Young MSM (ages 13 to 29) were most severely affected, representing more than one quarter of all new HIV infections nationally (27 percent; 12,900 in 2009)."  (Center for Disease Control, cdc.gov/nchhstp/newsroom/HIVIncidencePressRelease.html)
   2. 19% of MSM [men sex with men] are infected with HIV; 44% unaware they are infected: "A recent CDC study found that in 2008 one in five (19%) MSM in 21 major US cities were infected with HIV, and nearly half (44%) were unaware of their infection." (Center for Disease Control, cdc.gov/hiv/topics/msm/index.htm)
   3. Worldwide, 1% infected with HIV:  "Worldwide, approximately one in every 100 adults aged 15 to 49 is HIV-infected." (The Body, thebody.com/content/art6580.html)
   4. 53% of new HIV infections occur with MSM [men sex with men]: "MSM account for more than half of all new HIV infections in the U.S. each year (53%, or an estimated 28,700 infections)." (cdc.gov/nchhstp/newsroom/docs/fastfacts-msm-final508comp.pdf)
   5. MSM is 4% of population yet has HIV 44 time the rate of other men: While CDC estimates that MSM account for just 4 percent of the U.S. male population aged 13 and older, the rate of new HIV diagnoses among MSM in the U.S. is more than 44 times that of other men (range: 522–989 per 100,000 MSM vs. 12 per 100,000 other men). (cdc.gov/nchhstp/newsroom/docs/fastfacts-msm-final508comp.pdf)
   6. MSM group only group with increasing HIV infection rate:  "MSM are the only risk group in the U.S. in which new HIV infections are increasing. While new infections have declined among both heterosexuals and injection drug users, the annual number of new HIV infections among MSM has been steadily increasing since the early 1990s." (cdc.gov/nchhstp/newsroom/docs/fastfacts-msm-final508comp.pdf)
