Aging of HIV epidemic in India: Insights from HIV estimation modeling under the national aids control programme.

People living with HIV are gradually getting older as a result of better survival with increased uptake of antiretroviral treatment in India. We aimed to quantify the aging HIV-infected population in India by undertaking a mathematical model analysis of 2017 rounds of HIV burden estimations under the National AIDS Control Programme. Our analysis projects that the mean age of HIV-infected people will increase from 38.4 years in 2005 to 45.5 years in 2025 with the proportion of HIV-infected people aged 50 years or older increasing from 19% in 2005 to 37% in 2025. This aging HIV epidemic is anticipated to lead to more non-AIDS morbidities, increased treatment complexity, and an inevitable need for multidisciplinary health-care services to ensure continued high-quality survival.
