Abstract
Here we review the available evidence on adherence to highly active antiretroviral therapy (HAART) and its relationship with the risk of the dissemination of HIV-resistant viral strains in both developed and developing countries. We argue that referring to these issues of resistance and adherence to withhold or delay access to HAART in developing countries implicitly imposes a double standard of thinking that is unacceptable. Scaling-up access to HAART to succeed in low-resource settings, however, requires the long-term monitoring of adherence as well as the clarification of the complex trade-offs between minimizing the costs of therapeutic regimens and minimizing the risks of non-adherence and resistance.
