How many people have HIV and Aids
How many people have HIV and AIDS
Worldwide: UNAIDS estimates that 47.3 million people have been infected with HIV since the start of the global epidemic (42.9 million adults and 4.4 million children under 15). An estimated 13.9 million people have died with AIDS since the epidemic began (10.7 million adults and 3.2 million children under 15).
As of December 1998, there were an estimated 33.4 million people living with HIV infection or AIDS (32.2 million adults and 1.2 million children under 15). An estimated 5.8 million new HIV infections occurred in 1998. This represents almost 16,000 new cases per day. During 1998, HIV-associated illnesses caused the deaths of an estimated 2.5 million people, including 900,000 women and 510,000 children under 15.
In the United States: According to the Centers for Disease Control and Prevention (CDC), there are between 650,000 and 900,000 people living with HIV. Through December 1998, a total of 688,200 cases of AIDS had been reported to the CDC; of this number, 410,800 persons (representing 60% of cases) have died.

How safe is the U.S. blood supply? The U.S. blood supply is among the safest in the world. Nearly all people infected with HIV through blood transfusions received those transfusions before 1985, the year it became possible to test donated blood for HIV.
The Public Health Service has recommended a multifaceted approach to blood safety in the United States that includes stringent donor selection practices and the use of screening tests. Blood donations in the United States have been screened for antibody to HIV-1 since March 1985 and HIV-2 since June 1992. Blood and blood products that test positive for HIV are safely discarded and are not used for transfusion
An estimated one in 450,000 to one in 660,000 donations per year are infectious for HIV but are not detected by current antibody screening tests. In August of 1995 the FDA recommended that all donated blood and plasma also be screened for HIV-1 p24 antigen. Donor screening for p24 antigen is expected to reduce the number of otherwise undetected infectious donations by approximately 25 percent per year. The improvement of processing methods for blood products has also reduced the number of infections resulting in the use of these products. Currently the risk of infection with HIV in the United States through receiving a blood transfusion or through the use of blood products is extremely rare and has become progressively more infrequent, even in areas with high HIV prevalence rates.
How many people in the U.S. has H.I.V.?
It is estimated that more than one million people are living with HIV in the USA and that more than half a million have died after developing AIDS.
HIV statistics reported in the USA are currently only available for 37 states and 5 U.S. dependent areas with confidential name-based HIV infection reporting. AIDS statistics include all 50 states, the District of Columbia and five U.S. dependent areas. For more explanation, see the 'Interpreting HIV and AIDS statistics for the USA' section towards the end of this page.
The U.S. Centers for Disease Control and Prevention (CDC) estimates that at the end of 2007, there were 599,819 people living with a diagnosis of HIV infection in the 37 states and five U.S. dependent areas. However, the total number of people living with an HIV infection in the U.S. is thought to be around 1.1 million.1 The discrepancy between these figures is due to several factors, including:
During 2008, there were an estimated 42,439 new diagnoses of HIV infection in the 37 states and five dependent areas. Adult or adolescent males accounted for nearly three-quarters of new HIV diagnoses, more than two-thirds of whom were infected through male-to-male sexual contact. Heterosexual contact accounted for 15% of new infections among men and 84% among women. Injecting drug use was the transmission route in 9% of male and 15% of female diagnoses in 2008. In 2008 blacks/African Americans made up an estimated 50% of new diagnoses, whites 28%, and Hispanics/Latinos 19%. HIV was diagnosed in an estimated 182 children (<13 years at diagnosis) in 2008, all but 41 became infected through mother-to-child transmission.
AIDS diagnoses among children
An estimated 3,992 children (<13 years at diagnosis) were living with an AIDS diagnosis in 2007. The vast majority of these children acquired HIV through mother-to-child transmission. During 2008 there were an estimated 41 AIDS diagnoses among children, compared to 195 in 1999 and 896 in 1992. The decline in paediatric AIDS incidence is associated with a significant increase in HIV testing among pregnant women and the use of antiretroviral drugs to prevent mother-to-child transmission.
Deaths among people diagnosed with AIDS
In 1981, the first cases of what is now known as AIDS were reported in the U.S. During the 1980s there was a rapid increase in the number of reported AIDS cases and AIDS deaths. Cases peaked with the 1993 expansion of the case definition,3 and then declined. The most dramatic drops in both cases and deaths began in 1996, with the widespread use of combination antiretroviral therapy.
People with AIDS are now surviving longer and are contributing to a steady increase in the overall number of people living with AIDS. This trend will continue as long as the number of new diagnoses exceeds the number of people dying each year.
The number of deaths of persons with an AIDS diagnosis has stabilised in recent years at around 17,000-18,000 per year. (Deaths of persons with an AIDS diagnosis may be due to any cause).
Since the beginning of the epidemic, an estimated 597,499 people with AIDS have died in the U.S.
