Vietnam is currently facing an HIV epidemic that had affected approximately 280,000 people by the end of 2009. Injecting Drug Use (IDU) is principal driver of the HIV epidemic, contributing to between 32 % and 58 % of all HIV cases in various provinces. However, it has proven difficult to address the needs of IDUs, a high-risk group, given the prevalence of stigmatization and drug use in Vietnamese society. In addition, Vietnamese people are highly family oriented and most young IDUs have daily family contact of live in their parents' homes. Thus the burden on the family is substantial, and even greater if the IDU is HIV+.
