UPDATE COMING We’re currently working to update this article. that a person living with HIV who is on regular antiretroviral therapy that reduces the virus to undetectable levels in the blood is NOT able to transmit HIV to a partner during sex. This page will be updated soon to reflect the medical consensus that “Undetectable = Untransmittable.”

HIV-AIDS Statistics introHIV-AIDS Statistics intro

The U.S. Centers for Disease Control (CDC) reported the first five known cases of HIV in Los Angeles in June of 1981. The previously healthy gay men had contracted pneumonia and two died. Today, more than a million Americans have the virus.

Being diagnosed with HIV was once a death sentence. Now, a who begins treatment early can expect to live to 77 — the average lifespan of an average American man. The disease, which attacks the immune system, can be controlled by modern-day antiretroviral medications.

Prevalence, Incidence, and Death Rates: Then and Now

An estimated 1,155,792 Americans have HIV. About don’t know they have it.

An estimated were newly diagnosed with HIV in 2011, but only 32,052 developed AIDS. This is in striking contrast to the early days of HIV/AIDS.

According to the , of the 250,000 cases of reported AIDS cases, 200,000 already had died by 1992. By 2004, a million cases had been reported and 500,000 had died.

In 2010, of total AIDS deaths in the U.S. So far, have died.

Demographics: Who Gets HIV and How?

According to the , gay or bisexual men made up almost two-thirds of the 50,000 new infections in the U.S. in 2010. In 2011, 30,896 infections in the U.S. came as the result of . While gay men continue to represent most HIV infections in the U.S., anyone who practices unsafe sex or shares IVs can contract HIV. Among the 13,801 diagnosed in the U.S. in 2011, 4,775 men and 9,026 women contracted the virus.

When it comes to , 23,042 of those diagnosed in the U.S. in 2011 were black, 13,817 were white, and 10,135 were Latino. Infection rates in the U.S. of black men and women have risen to based on population size.

Of in the U.S. in 2011:

  • 38,825 were adult and adolescent males
  • 10,257 were adolescent females
  • 192 were children under age 13

Americans in the had the most diagnoses: 8,054. Next highest were those ages 25 to 29 (7,484) and 30 to 34 (6,209).

Five states alone make up almost half of new diagnoses in the U.S. in 2011.  These five states account for 23,923 of 49,273 new infections, according to the :

  • California
  • Florida
  • Texas
  • New York
  • Georgia

According to , 33.4 million people worldwide are living with HIV/AIDS, and 25 million have died since 1981. Additionally, 97 percent of people with HIV live in developing and moderate-income nations, such as those in sub-Saharan Africa.

on other continents:

  • Asia: 4.7 million
  • Latin America: 2 million
  • Eastern Europe and Central Asia: 1.5 million

The reports that access to care has increased tenfold from 2002 to 2008 among poor countries hit hard by HIV. Still, people most at risk around the world do not have access to treatment or prevention. Just over one-third of the 28.6 million people in poor and moderate-income countries who should be on antiretroviral medication are getting it.

Prevention: Protect Yourself and Your Loved Ones

It’s important for people — especially high-risk groups — to be tested frequently. Starting HIV treatment early is important for best outcomes. Approximately of people ages 18 to 64 in the U.S. have reported receiving an HIV test. HIV education is mandatory in and in Washington, D.C.

Preventing transmission of HIV is as important as treating those who have it, from a public health perspective. There has been remarkable progress in that regard. For example, modern-day antiretroviral therapy can reduce the chances of an HIV-positive person transmitting the virus by .

There has been a sharp decline in transmission rates in the U.S. since the mid-1980s: . However, transmission rates from 2008 to 2010 among gay and bisexual men, who comprise the U.S. population most at risk. While gay and bisexual men represent only 4 percent of the male population in the U.S., they comprise .

Condom use remains an inexpensive, cost-effective first line of defense against HIV. A new pill known as Truvada, or pre-exposure prophylaxis (PrEP), also offers protection. An HIV-negative person can protect themselves from contracting HIV by taking a once-a-day pill. When taken properly, PrEP can by more than 90 percent.

Cost of HIV/AIDS

There is still no cure for HIV, and it can take a huge financial toll on those living with it. The U.S. is expected to spend almost on HIV/AIDS programs, including:

  • research
  • housing
  • treatment
  • prevention

Of that amount, $6.5 billion is for aid abroad. This expenditure represents less than 1 percent of the federal budget. HIV/AIDS funding has increased almost $5 billion since 2009.

Not only are life-saving medications expensive, but massive numbers of people in hard-hit countries with limited resources have died or are unable to work due to HIV/AIDS. This has affected these nations’ development.

Unlike diseases that affect children or the elderly, HIV hits people during their working years. Countries end up with lost productivity and, in many cases, a significant reduction in the workforce. This all adds up to severe impacts on these national economies.

According to the , Zambia has “lost” more than 1.6 million people to HIV/AIDS — almost 12 percent of its population. Tanzania is “missing” more than 3.2 million people to HIV/AIDS — 7 percent of its population. Kenya, Uganda, and Mozambique have been similarly hard hit.

Some African countries such as Ethiopia, Kenya, and Zimbabwe spend between an estimated of their total health ministry budget on HIV/AIDS.

The average cost of treating a person with HIV over the course of their lifetime is $379,668. The reports that prevention interventions are deemed cost effective if they prevent an infection in one person for less than that.
