How Many New Hiv Infections Per Year In Us

Hiv Incidence: Estimated Annual Infections In The Us 2010

How to end HIV transmission in the United States

The dramatic decline in annual HIV infections has stopped and new infections has stabilized in recent years, according to a CDC report published today. The report provides the most recent data on HIV trends in America from 2010 to 2016. It shows that after about five years of substantial declines, the number of HIV infections began to level off in 2013 at about 39,000 infections per year. In addition to the overall trend, the new report examines HIV infections among multiple subgroups. Data indicate that annual HIV infections declined in some populations, but increased in others. CDC estimates that the decline in HIV infections has plateaued because effective HIV prevention and treatment are not adequately reaching those who could most benefit from them.

Key Points: Hiv Diagnoses

Gay, bisexual and other men who have sex with men b are the population most affected by HIV in the U.S.:

  • MSM accounted for 69% of new HIV diagnoses in the United States.c
  • From 2015 through 2019 in the United States and 6 dependent areas, Black/African American MSM accounted for more than 36% and White MSM accounted for more than 30% of HIV diagnoses among MSM annually.
  • In 2019, Black/African American MSM accounted for 26% of new HIV diagnoses and 37.9% of diagnoses among all MSM.
  • In 2019, Hispanic/Latinod MSM made up 22% of new HIV diagnoses and 32.5% of diagnosis among all MSM.

The number of HIV diagnoses decreased among MSM overall, but trends varied by race/ethnicity. From 2015 through 2019:

  • Among MSM aged 1324 years, HIV diagnoses decreased or were stable among all racial/ethnic groups.
  • HIV diagnoses increased among American Indian/Alaska Native and Native Hawaiian/other Pacific Islander MSM, ages 24 and older.

Transgender people accounted for approximately 2% of new HIV diagnoses in 2019.

  • From 2015 through 2019 in the United States and 6 dependent areas, the number of diagnoses of HIV infection for transgender adults and adolescents increased.
  • In 2019, among transgender adults and adolescents, the largest percentage of diagnoses of HIV infections was for transgender male-to-female people.

Blacks/African Americans and Hispanics/Latinx continue to be severely and disproportionately affected by HIV:

Global Hiv And Tb Response

HIV and tuberculosis are the worlds two most deadly infectious diseases. Additionally, these two epidemics are tragically interconnected, as TB is the leading cause of death for those living with HIV.

CDCs Division of Global HIV & TB, through the U.S. Presidents Emergency Plan for AIDS Reliefexternal icon, is tackling these two epidemics to produce the greatest impact. Our experts are working on the front lines in more than 45 countries and regions around the globe, focused on a single mission: to fight these diseases and, ultimately, bring an end to the dual epidemics of HIV and TB worldwide.

Hiv Prevention Programmes In Thailand

HIV

In 2018, 6,400 people in Thailand became infected with HIV. Roughly two-thirds ;were men . Under 100 new infections were among children .57

New infections are declining significantly, though the rate has slowed in recent years. Between 2010 and 2018 new infections fell by 59%, the steepest decline for any country in the Asia and the Pacific region.5859

In 2018, it was estimated that around 40% of new infections occurred among men who have sex with men and transgender women, 10% among sex workers and their clients, and 11% among people who inject drugs. Around 29% of new infections are estimated to occur from spousal transmission, 21% of these from husbands to wives.60

Thailands 20172030 National AIDS Strategy aims to cut annual new infections to less than 1,000 by supporting combination prevention programmes for key populations and working in partnership with community-led organisations to reach people at higher risk in the locations where they live and work.61

Impact Across The Country

  • Although HIV has been reported in all 50 states, the District of Columbia, and U.S. dependencies, the impact of the epidemic is not uniformly distributed.
  • Ten states accounted for about two-thirds of HIV diagnoses among adults and adolescents in 2019 .31 Regionally, the South accounted for more than half of HIV diagnoses in 2019.32
  • Rates of HIV diagnoses per 100,000 provide a different measure of the epidemicâs impact, since they reflect the concentration of diagnoses after accounting for differences in population size across states. The District of Columbia has the highest rate in the nation, compared to states, nearly 3 times the national rate and Georgia was the state with highest rate , twice that of the national rate.33,34 Nine of the top 10 states by rate are in the South.35
  • New HIV diagnoses are concentrated primarily in large U.S. metropolitan areas , with Miami, Orlando, and Atlanta topping the list of the areas most heavily burdened.36

Hiv Care & Viral Suppression

Young People Make Up More Than Quarter of New U.S HIV Cases

92% of people newly diagnosed with HIV in 2019 entered care within one month of their diagnosis .

Between January and June 2020, 77% of persons diagnosed were virally suppressed within six months .

Among all people living with HIV in San Francisco, 67% have their virus under control in 2020. . People who are virally suppressed have better health outcomes and do not transmit HIV to other people.

The proportions of persons with HIV who received care and were virally suppressed in 2019 were higher in San Francisco than in California and the U.S. .

Black/African Americans had a lower proportion of linkage to care and viral suppression. Trans women, persons aged 30-39 years, MSM-PWID, and persons experiencing homelessness at diagnosis had a lower proportion of viral suppression. .

Among persons diagnosed with AIDS in the years 2012-2019, survival probability at 36 months was lower among Black/African Americans and Whites compared to Latinx and Asians/ Pacific Islanders. .

Populations Most Affected By Hiv In The Usa

The;HIV epidemic in the USA has impacted some groups more than others. These groups, sometimes referred to as key populations, can be grouped by transmission category (for example, but also by race and ethnicity, with people of colour having significantly higher rates of HIV infection over white Americans.11

A complex set of economic and socio-economic factors drive risk to these populations, including discrimination, stigma, poverty and a lack of access to care.12 Sexual networks also present a major risk factor as populations at a high risk of HIV tend to have sex with people in their own communities.

Antiretroviral Treatment In Thailand

Thailand provides antiretroviral treatment for free as part of the countrys universal health insurance scheme. In 2014 it adopted World Health Organization guidance to provide immediate ART to anyone testing positive for HIV, regardless of their CD4 count .83It is one of only four countries in Southeast Asia;that has enabled 70% or more people living with HIV to access ART, with 75% on treatment as of 2018 the others being Cambodia , Myanmar and Singapore .84

In 2016, 75% of HIV positive adults were receiving treatment, as were 83% of children.85Women are more likely than men to be on treatment, with 77% of women living with HIV on treatment compared to 73% of men.86 This is partly due to the fact that men who have sex with men are less likely than other groups to access treatment. In 2018, only 61% of men who have sex with men and transgender women who were newly diagnosed received ART in the same year. However, this rate is higher than among female sex workers , male sex workers and people who inject drugs .PEPFAR Asia Region Operational Plan, ROP 2019 Strategic Direction Summary, p51.

Adherence support is also another major focus area, and has resulted in 90% of people on ART still retained in care after 12 months in 2018.89 Treatment programmes tend to be particularly strong in large cities; to fully realise the potential of these strategies they need to be extended to other parts of the country.90

How many people living with HIV in Canada acquired HIV through heterosexual sex?

According to national HIV estimates, 20,750 people living with HIV in Canada acquired HIV through heterosexual sex in 2018. This represents 33.4% of all people with HIV in Canada.

In 2016, the Public Health Agency of Canada separated heterosexual transmission into two categories those born in an HIV-endemic country and those born in a non HIV-endemic country . According to the Public Health Agency of Canada This separation is no longer considered appropriate, for reasons of increasing data incompleteness. The Public Health Agency of Canada is working with communities and with provinces and territories to find ways to better reflect the HIV situation in these communities.

People Who Inject Drugs

It is now widely accepted that the USA is experiencing a nationwide public health emergency in the form of an opioid epidemic.3940

Heroin use is increasing in the USA among men and women in most age groups and across all income levels, rising by 63% between 2002 and 2013 alone. A study published in 2019 estimated that more than 750,000 people in the USA inject drugs and that this number is rising.41

A huge contributing factor to this is misuse of prescription opioids, which has seen an increasing number of people turn to injecting drug use, particularly in non-urban areas where previously, injecting drugs had not been a significant issue. This has created new HIV prevention challenges as it has placed more people at risk of HIV.

Between 2010 and 2016, new infections among people who inject drugs fell by 30% overall.42 However, there are concerns that the level of new infections may have stagnated or reversed in recent years due to increased levels of injecting.4344;

Evidence is emerging of increases in hepatitis C infections and new, localised outbreaks of HIV.45 For instance, Scott County in Indiana, with a population of only 23,744, experienced 181 new HIV infections in 2015.46

The impacts of the opioid epidemic are far reaching: the US has experienced the fastest proportional rise of drug-related overdose deaths ever recorded, which rose by 21.4% between 2015-2016 alone.47

Men Who Have Sex With Men

Men who have sex with men are the group most affected by HIV in the USA, accounting for an estimated 2% of the population, but 66% of new annual HIV infections.13 At the end of 2015, the most recent data available, around 632,300 USA-based men who have sex with men were living with HIV. One in six of these people were unaware they were HIV positive.14

Between 2010 and 2016, new HIV infections among men who have sex with men remained stable at about 26,000 a year.15 However, trends vary greatly by age and ethnicity. For example, new infections among African American/black men who have sex with men remained stable overall, at about 10,000 new infections but they increased by 65% among those aged 25 to 34 . Among Latino and Hispanic men who have sex with men, new infections rose by around 30%, from 6,400 to 8,300. Again, the greatest rise was among 25 to 34-year-olds, where new infections increased by 68%. Among white men who have sex with men, new infections decreased to less than a-fifth overall, from 8,000 to 6,700.16

In 2016, it was estimated that, if current diagnosis rates continued, one in six American men who have sex with men would be diagnosed with HIV in their lifetime. This equates to one in two African American/black men who have sex with men, one in four Hispanic/Latino men who have sex with men and one in 11 white men who have sex with men.17

The Global Hiv/aids Epidemic

HIV, the virus that causes AIDS, is one of the worlds most serious public health challenges. But there is a global commitment to stopping new HIV infections and ensuring that everyone with HIV has access to HIV treatment.

According to UNAIDS:

Number of People with HIVThere were approximately 37.6 million people across the globe with HIV in 2020. Of these, 35.9 million were adults and 1.7 million were children .

New HIV InfectionsAn estimated 1.5 million individuals worldwide acquired HIV in 2020, marking a 30% decline in new HIV infections since 2010. Of these new HIV infections:

  • 1.3 million were among adults
  • 160,000 were among children

HIV TestingApproximately 84% of people with HIV globally knew their HIV status in 2020. The remaining 16% still need access to HIV testing services. HIV testing is an essential gateway to HIV prevention, treatment, care and support services.

HIV Treatment AccessAs of the end of 2020, 27.4 million people with HIV were accessing antiretroviral therapy globally. That means 10.2 million people are still waiting. HIV treatment access is key to the global effort to end AIDS as a public health threat. People with HIV who are aware of their status, take ART daily as prescribed, and get and keep an undetectable viral load can live long, healthy lives and have effectively no risk of sexually transmitting HIV to their HIV-negative partners.

  • 84% knew their HIV status
  • 73% were accessing ART
  • 66% were virally suppressed
