Ann Intern Med; ePub 2018 Mar 20; Singh, et al

Modeled HIV incidence decreased nearly 15% overall from 2008 to 2015, and among all transmission risk group except men who have sex with men (MSM), a recent study found. The cross-sectional analysis included persons aged ≥13 years with diagnosed HIV infection and estimated HIV incidence and prevalence as well as the percentage of undiagnosed HIV infections overall and among MSM. Researchers found:

  • HIV incidence decreased 14.8% overall, from 45,200 infections in 2008 to 38,500 in 2015, and among all transmission risk groups except MSM.
  • The incidence of HIV increased 3.1% per year among Hispanic/Latino MSM, decreased 2.7% per year among white MSM, and remained stable among black MSM.
  • The incidence decreased by 3.0% per year among MSM aged 13-24 years and by 4.7% per year among those aged 35-44 years.
  • Among MSM aged 25-34 years, HIV incidence increased 5.7% per year.
  • The percentage of undiagnosed HIV infections was higher among black, Hispanic/Latino, and younger MSM than white and older MSM, respectively.
