How Does Cdc Know The Number Of People Living With Hiv If Some Of Those People Are Unaware Of Their Status
CDC estimates the number of people living with HIV by using a scientific model. This model helps CDC estimate the number of new HIV infections and how many people are infected but dont know it. HIV prevalence is the number of people living with HIV infection at a given time, such as at the end of a given year. More information on HIV prevalence.
How Hiv Affects Different Groups Of People**
African Americans are most affected by HIV. In 2015, African Americans made up only 12% of the US population, but had 42% of all new HIV infections. Additionally, Hispanic/Latinos are also strongly affected. They make up 17% of the US population, but had 26% of all new HIV infections.
Young people, aged 13-24 are especially affected by HIV. They comprised 16% of the US population, but accounted for 26% of all new HIV infections in 2010. All young people are not equally at risk, however. Young men who have sex with men , for example, accounted for 72% of all new infections in people aged 13-24, and young, African American MSM are even more severely affected. According to the Centers for Disease Control, “In 2010, African American gay, bisexual, and other men who have sex with men represented an estimated 72% of new infections among all African American men and 36% of an estimated 29,800 new HIV infections among all gay and bisexual men. More new HIV infections occurred among young African American gay and bisexual men than any other subgroup of gay and bisexual men.”
Gay, bisexual, and MSM of all races and ethnicities remain the population most profoundly affected by HIV. In 2015, MSM had 68% of all new HIV infections, even though they made up only around 2% of the population. Individuals infected through heterosexual sex made up 25.3% of all new HIV infections in 2015.
Although Strides Have Been Made In The Hiv Response Children Are Still Affected By The Epidemic
Of the estimated 38.4 million people living with HIV worldwide in 2021, 2.73 million were children aged 019. Each day in 2021, approximately 850 children became infected with HIV and approximately 301 children died from AIDS related causes, mostly because of inadequate access to HIV prevention, care and treatment services.
As of 2021, roughly 14.9 million children under the age of 18 had lost one or both parents to AIDS-related causes. Millions more have been affected by the epidemic, through a heightened risk of poverty, homelessness, school dropout, discrimination and loss of opportunities, as well as COVID-19. These hardships include prolonged illness and death. Of the estimated 650,000 people who died of AIDS-related illnesses in 2021, 110,000 of them were children under 20 years of age.
In 2021, around 160,000 children aged 09 were newly infected with HIV, bringing the total number of children aged 09 living with HIV to 1.02 million . Nearly 86 per cent of these children live in sub-Saharan Africa. One bright spot on the global horizon is the rapid decline of approximately 52 per cent in new HIV infections among children aged 09 since 2010 due to stepped-up efforts to prevent mother-to-child transmission of HIV. However, the number of new HIV infections among adolescents has declined at a slower rate of about 40 per cent.

The Status Of The Hiv/aids Epidemic In Sub
Senior Fellow, Futures Group International
Despite the fact that sub-Saharan Africa contains only about 11 percent of the Earths population, the region is the worlds epicenter of HIV/AIDS. The numbers are daunting. Adult HIV prevalence is 1.2 percent worldwide , but it is 9.0 percent in sub-Saharan Africa. UNAIDS estimates that at the end of 2001, there were 40 million people living with HIV/AIDS, 28.5 million of them from sub-Saharan African. Five million adults and children became newly infected with HIV in 2001, 3.5 million of them from sub-Saharan Africa. Three million people died from AIDS-related causes in 2001, and 2.2 million of these deaths were among sub-Saharan Africans.2
AIDS is now the leading cause of death in sub-Saharan Africa. Life expectancy at birth has plummeted in many African countries, wiping out the gains made since independence. The combination of high birth rates and high AIDS mortality among adults, including many parents, has meant that more than 90 percent of children who have been orphaned as a consequence of the HIV/AIDS epidemic are in this region.2
According to UNAIDS, all the worst affected countries are contiguous to one another in the lower part of the continent. These include South Africa, Lesotho, Swaziland, Botswana, Namibia, Zambia, and Zimbabwe. Botswana, Lesotho, Swaziland, and Zimbabwe have prevalence rates above 30 percent.4

Hiv/aids Is One Of The Worlds Most Fatal Infectious Disease
Almost 1 million people die from HIV/AIDS each year in some countries its the leading cause of death
HIV/AIDS is one of the worlds most fatal infectious diseases particularly across Sub-Saharan Africa, where the disease has had a massive impact on health outcomes and life expectancy in recent decades.
The Global Burden of Disease is a major global study on the causes of death and disease published in the medical journal The Lancet.1 These estimates of the annual number of deaths by cause are shown here. This chart is shown for the global total, but can be explored for any country or region using the change country toggle.
In the chart we see that, globally, it is the second most fatal infectious disease.
According to the Global Burden of Disease study, almost one million people died from HIV/AIDS in 2017. To put this into context: this was just over 50% higher than the number of deaths from malaria in 2017.
Its one of the largest killers globally but for some countries particularly across Sub-Saharan Africa, its the leading cause of death. If we look at the breakdown for South Africa, Botswana or Mozambique which you can do on the interactive chart we see that HIV/AIDS tops the list. For countries in Southern Sub-Saharan Africa, deaths from HIV/AIDS are more than 50% higher than deaths from heart disease, and more than twice that of cancer deaths.

Us Response To The Global Epidemic
The U.S. President’s Emergency Plan for AIDS Relief is the U.S. Governments response to the global HIV/AIDS epidemic and represents the largest commitment by any nation to address a single disease in history. Through PEPFAR, the U.S. has supported a world safer and more secure from infectious disease threats. It has demonstrably strengthened the global capacity to prevent, detect, and respond to new and existing riskswhich ultimately enhances global health security and protects Americas borders. Among other global results, PEPFAR provided HIV testing services for more than 50 million people in Fiscal Year 2021 and, as of September 30, 2021, supported lifesaving ART for nearly 18.96 million men, women, and children. PEPFAR also enabled 2.8 million babies to be born HIV-free to parents living with HIV.
In addition, the National Institutes of Health represents the largest public investment in HIV/AIDS research in the world. NIH is engaged in research around the globe to understand, diagnose, treat, and prevent HIV infection and its many associated conditions, and to find a cure.

Is The World Making Progress In Its Fight Against Hiv/aids
The 1990s saw a substantial increase in the number of people infected with HIV and dying of AIDS.
Between 1996 and 2001 more than 3 million people were infected with HIV every year. Since then the number of new infections began to decline and in 2019 it was reduced to below 2 million. The lowest number of new infections since 1990.
The number of AIDS-related deaths increased throughout the 1990s and reached a peak in 2004, 2005 when in both years close to 2 million people died. Since then the annual number of deaths from AIDS declined as well and was since halved. 2016 was the first year since the peak in which fewer than 1 million people died from AIDS.
The chart also shows the continuing increase in the number of people living with HIV. The rate of increase has slowed down compared to the 1990s, but the absolute number is at the highest ever with more than 36 million people globally living with HIV.

Hiv Infections By State
In the United States, where you live plays a large part in how likely you are to get HIV. While it is clear that dense urban populations with high prevalence rates contribute to the risk, there are other unique factors that account for a growing disparity between U.S. states.
A prime example is the rate of infection in states that have either adopted or refused Medicaid expansion, intended to expand healthcare to economically disadvantaged people.
According to the CDC, the 13 states that refused Medicaid expansion account for 42% of all new infections. Florida, Texas, Georgia, and North Carolina represent the lion’s share of these infections.
Poverty remains a driving force for HIV infections, particularly in the South where the rates of poverty are highest. Moreover, nearly half of all Americans without health insurance live in the South.
With that being said, the Northeast has a higher prevalence rate overall, centered mainly in dense urban populations like New York City, Baltimore, and Washington, D.C.
These dynamics are reflected in the 10 U.S. states with the highest HIV prevalence rates, according to the CDC.
|65 and over
Youth also accounts for the highest rate of undiagnosed infections. Today, nearly half of all HIV-positive youth between the ages of 13 and 24 are unaware of their status and, as a result, are more likely to infect others. The picture is little improved among adults 25 to 34, where one in three remains undiagnosed.
