More people with HIV are achieving viral suppression in US, but about 40% remain above transmission thresholds

A growing proportion of people with HIV are reaching an undetectable viral load on antiretroviral therapy (ART), according to a pair of studies from the US Centers for Disease Control and Prevention presented at the Conference on Retroviruses and Opportunistic Infections (CROI 2016) last month in Boston. Despite this improvement, however, a substantial number of people are still not achieving viral suppression, putting them at risk for disease progression and onward transmission of the virus.

Experts have developed the 'continuum of care' concept to characterise how people with HIV progress through the steps of diagnosis, linkage to care, starting ART and achieving viral suppression. In 2014 the CDC reported that while 86% of the estimated 1.2 million people living with HIV in the US in 2011 had been diagnosed, just 40% were engaged in HIV medical care and only 30% had achieved undetectable viral load.
