Abstract
It is widely acknowledged that the HIV and AIDS pandemic is a global emergency and that cheap, effective treatment should be provided for as many people as possible worldwide. But there are many challenges to rolling out antiretroviral treatment in resource-poor settings. These include the cost of drugs, sustaining their supply and distribution, the complexity of treatment regimens, selection of patients for treatment, shortage of medical and nursing personnel, inadequacy of healthcare facilities, the need for uninterrupted, lifelong treatment, and monitoring for drug resistance. Great efforts, nationally and internationally, are required to meet these challenges.
