Why Is HIV and Aging Important? 1980s meets 2010s

1980s AIDS Crisis 1980s AIDS Crisis HIV/AIDS primarily a disease of young and middle-aged men HIV/AIDS primarily a disease of young and middle-aged men 2010s 2010s Convergence of HIV epidemic and aging of America Convergence of HIV epidemic and aging of America Consequence of medical success Consequence of medical success Success in treatment of HIV Success in treatment of HIV Success in non-HIV related treatments, Americans living longer Success in non-HIV related treatments, Americans living longer

Why the Intersection of Aging and HIV? HIV in older adults due to: HIV in older adults due to: Improved survival of persons with HIV Improved survival of persons with HIV Acquisition of HIV among older persons Acquisition of HIV among older persons Likely more common than recognized Likely more common than recognized Likely ↑ mucosal risk of HIV acquisition in elderly Likely ↑ mucosal risk of HIV acquisition in elderly
