In the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Aphyra Chheav, a member of the Key Correspondents program, advocates that prisoners in Cambodia should have access to treatment for illicit drug use. “…One motivation to provide better drug treatment for prisoners relates to the global ambition to prevent new HIV infections. Dependence on opioids, such as heroin, is linked to higher rates of HIV infection due to the risks of sharing injecting equipment which is contaminated. … Many organizations are working together in Cambodia, including UNAIDS, AusAIDS and KHANA, among others, who believe substitution services and rehabilitation must be made available to people in prison” (1/17).
