Antiretroviral therapies against HIV have been in use for more than 30 years and have enabled people living with HIV to maintain undetectable viral levels. Many of them are aging in good health.

Yet, it is still unknown what this reservoir is like, which cells are affected, and which comorbidities are typical of aging or are associated with the virus.
