HIV drug resistance surveillance in low- and middle-income countries: 2004 to 2010

摘要

BackgroundAt the end of 2011, over 8 million people were receiving antiretroviral therapy (ART) in low- and middle-income countries (LMIC), a 26-fold increase from 2003. Some degree of HIV drug resistance (HIVDR) will emerge among populations on combination ART even when high levels of adherence are achieved. In 2004, the World Health Organization (WHO) initiated global HIVDR surveillance to monitor emergence and transmission of HIVDR in countries scaling-up ART.
