Graf and Una O’Doherty Purpose of review Integrated HIV DNA can give rise to infectious virus, and therefore may be a surrogate of reservoir size.

This review highlights the technical hurdles involved in measuring integrated HIV DNA, progress toward overcoming these hurdles by repetitive sampling and recent important in-vivo findings monitoring this HIV DNA intermediate. Recent findings The dynamics of integration levels after antiretroviral therapy may provide clues to how reservoirs accumulate over time and why early intervention may be beneficial.
