Writing in the PLOS “Speaking of Medicine” blog, “Helen Bygrave of Médecins Sans Frontières (MSF) considers the challenges of making HIV viral load testing an effective reality in sub-Saharan Africa.” She concludes, “In summary, sorting out the technical issues seems, dare I say it, to be the easy part. It would be a huge mistake for the HIV world to financially invest at scale in a test that is not properly implemented. The aim should be to not just retain patients on [antiretroviral therapy (ART)] but to retain them with an undetectable viral load. If the introduction of viral load monitoring is to be a success, laboratory and ART program managers and patients need to work together to achieve this goal” (1/27).
