residents living with the virus in 2008 to 1,122,900 in 2015. HIV prevalence increased 14.7 percent during the study period, rising from 956,200 U.S. Consequently, they had the highest rate of annual HIV infections per 100,000 people among all risk groups, at 514 transmissions, a rate 16 times greater than that of PWID (32 transmissions per 100,000) and 135 times that of heterosexuals (3.8 transmissions per 100,000). population and accounted for 67 percent of all those diagnosed with HIV in 2015. MSM make up an estimated 2 percent of the U.S. During this time HIV, incidence among those 13 to 24 years old declined 3 percent per year, from 9,800 to 7,700 transmissions rose 5.7 percent per year among those 25 to 34 years old, from 6,900 to 10,000 (a 44.9 percent increase overall) declined 4.7 percent per year among those 35 to 44 years old remained essentially unchanged among those 45 to 44 years old, at a respective 3,300 and 3,000 and rose 4.1 percent per year among those age 55 and older, from 1,000 to 1,300 (a 30 percent increase overall).Īmong MSM, HIV incidence broken down by ethnicity saw essentially no change between 20 in the rate among African Americans, from 9,900 to 9,800 transmissions a 3.1 percent rise per year among Latinos, from 6,300 to 7,900 (a 25.4 percent increase overall) and essentially no change among Asians, at a respective 530 and 490. HIV incidence among MSM remained essentially stable: 26,700 members of this population contracted the virus in 2008 compared with 26,200 in 2015. This could be a sign that the opioid crisis stands poised to reverse some of the hard-fought gains, such as access to syringe exchange services, that have driven down incidence among this population since the early 2000s. The decline in HIV incidence seen among PWID seems to be leveling off, given the fact that the rate remained stable in 20. Note: All figures quoted from the report regarding HIV prevalence (the number of people living with the virus), HIV incidence and the proportion of the HIV population that is undiagnosed are estimates.īetween 20, the number of people who contracted HIV annually in the United States declined 14.8 percent, from 45,200 to 38,500.ĭuring this period, HIV incidence attributable to heterosexual contact declined 6.3 percent annually, from 13,000 to 8,800 additionally, the rate declined 10.7 percent annually among people who inject drugs (PWID), from 3,800 to 2,200 and 4.3 percent among MSM who inject drugs, from 1,500 to 1,200. They fed that data into a mathematical model that estimated the time of each infection to develop estimates regarding how many people in various subgroups contracted the virus annually.
The CDC recently estimated that about half of those living with the virus had a fully suppressed viral load in 2014, and epidemic trends suggest that the figure has likely risen in the years since.įor their new report, CDC researchers relied on data from the National HIV Surveillance System (NHSS), looking at new diagnoses and the first CD4 test result following diagnosis among individuals age 13 and older.
The risk of transmission by people with HIV who maintain an undetectable viral load thanks to ARV treatment is effectively zero, according to the cumulative findings of multiple large studies.

The CDC has stated that the declining overall HIV rate seen in recent years is likely driven by a rising rate of full suppression of the virus among those living with HIV in the United States. Prior to 2008, HIV incidence was essentially stable in the United States for the decade following the beginning of the modern era of combination antiretroviral (ARV) treatment.
This new estimate, therefore, represents a disappointing reduction in that hopeful figure.
Published in the Annals of Internal Medicine, the report is a more precise and granular version of reports on epidemic trends that CDC officials presented at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle a year ago.Īt that time, the agency estimated that HIV incidence declined 18 percent between 20. These figures come from the Centers for Disease Control and Prevention’s (CDC) new, in-depth analysis of epidemic trends in the United States. During this period, HIV incidence among 25- to 34-year-old men who have sex with men (MSM) increased by an estimated 45 percent while the rate increased 25 percent among Latino MSM. While the national annual HIV infection rate dropped by an estimated 15 percent between 20, a few key subgroups saw a rise in yearly new HIV infections, also known as HIV incidence.
